Architected for the cloud-first and remote-first deployments, MVISION Cloud Firewall secures access to applications and resources on the internet, accessed from every remote site and location, through a cloud-native service model. The solution inspects end-to-end user traffic – across all ports and protocols, enabling unified visibility and policy enforcement across the organizational footprint. Powered by McAfee Enterprise’s industry leading next-generation intrusion detection and prevention system, contextual policy engine and advanced threat detection platform, and supported by Global Threat Intelligence feeds, MVISION Cloud Firewall proactively detects and blocks emerging threats and malware with a high degree of accuracy, uniquely addressing the security challenges of the modern remote workforce. MVISION Cloud Firewall is an integral component of McAfee Unified Cloud Edge, offering organizations an all-encompassing, cloud-delivered Secure Access Service Edge (SASE) security solution for accelerating their business transformation.
For a long time, firewalls and computer networks were like conjoined twins. Businesses simply could not afford to run an enterprise network without deploying a security system at the edge to create a secure perimeter around their crown jewels. The growing adoption of web-based protocols and their subsequent employment by cybersecurity adversaries for launching targeted malware attacks, often hidden within encrypted traffic, saw the emergence of next-generation firewall (NGFW) solutions. Apart from including stateful firewall and unified threat management services, NGFWs offered multi-layered protection and performed deep packet inspection, allowing organizations greater awareness and control over the applications to counter web-based threats.
But things took a dramatic turn with the introduction of cloud computing. Cloud service providers came up with an offer the organizations could not refuse – unlimited computing power and storage volumes at significantly lower operating costs, along with the option to seamlessly scale business operations without hosting a single piece of hardware on-premises. Hence began the mass exodus of corporate data and applications to the cloud. Left without a fixed network perimeter to protect, the relationship between firewalls and networks entered complicated terms. While the cloud service providers offered a basic level of security functionality, they lacked the muscle power of on-premises firewalls, particularly NGFWs. This was further exacerbated by the ongoing pandemic and the overnight switch of the workforce to remote locations, which introduced the following challenges:
The distributed workforce has expanded the threat landscape at an alarming rate. According to the latest McAfee Labs Threats Reports, the volume of malware threats observed by McAfee Labs averaged 688 threats per minute, an increase of 40 threats per minute (3%) in the first quarter of 2021. While SWGs and CASBs could address the security challenges for web and SaaS traffic, respectively, how could organizations secure the remaining non-web traffic? The answer lies in Firewall-as-a-Service, or FWaaS. FWaaS can be defined as a firewall hosted in the cloud, offering all the NGFW capabilities, including deep packet inspection, application-layer filtering, intrusion prevention and detection, advanced threat protection, among others. While, at the onset, FWaaS may give the impression of lifting and shifting NGFWs to the cloud, their business benefits are far more profound and relevant for the modern workforce, some of which include:
McAfee MVISION Cloud Firewall is a cutting-edge Firewall-as-a-Service solution that enforces centralized security policies for protecting the distributed workforce across all locations, for all ports and protocols. MVISION Cloud Firewall allows organizations to extend comprehensive firewall capabilities to remote sites and remote workers through a cloud-delivered service model, securing data and users across headquarters, branch offices, home networks and mobile networks, with real-time visibility and control over the entire network traffic.
The core value proposition of MVISION Cloud Firewall is characterized by a next-generation intrusion detection and prevention system that utilizes advanced detection and emulation techniques to defend against stealthy threats and malware attacks with industry best efficacy. A sophisticated next-generation firewall application control system enables organizations to make informed decisions about allowing or blocking applications by correlating threat activities with application awareness, including Layer 7 visibility of more than 2000 applications and protocols.

Superior IPS efficacy: MVISION Cloud Firewall delivers superior IPS performance through deep inspection of network traffic and seamless detection and blocking of both known and unknown threats across the network perimeter, data center, and cloud environments. The next-generation IPS engine offers 20% better efficacy than competitive solutions, while far exceeding the detection rates of open-source solutions. The solution combines with MVISION Extended Threat Detection and Response (XDR) to offer superior threat protection by correlating threat intelligence and telemetry across multiple vectors and proactively detecting and resolving adversarial threats before that can lead to any enterprise damage or loss. Additional advantages include inbound and outbound SSL decryption, signature-less malware analysis, high availability, and disaster recovery protection.
End-to-end visibility and optimization: The ability to visualize and control remote user sessions allows MVISION Cloud Firewalls to proactively monitor the end-to-end traffic flow and detect any critical issues observed across user devices, networks, and cloud. This offers network administrators a unified, organization-wide view of deployed assets to pinpoint and troubleshoot issues before the overall network performance and user productivity gets impacted. Optimizing network performance elevates the user experience through reduced session latency while keeping a check on the help desk ticket volumes.
Policy Sophistication: MVISION Cloud Firewall considers multiple contextual factors, such as the device type, security posture of devices, networks and users, and pairs that with application intelligence to define a robust and comprehensive policy lexicon that is more suitable for protecting the modern remote workforce. For example, most NGFWs can permit or block user traffic based on the configured rule set, such as permitting accounting users to access files uploaded on a Teams site. McAfee, on the other hand, utilizes its data protection and endpoint protection capabilities to create more powerful NGFW rules, such as permitting accounting users to access a third-party Teams site only if they have endpoint DLP enabled.
MVISION Cloud Firewall converges with MVISION Unified Cloud Edge to offer an integrated solution comprising of industry best Cloud Access Security Broker (CASB), Secure Web Gateway (SWG), Zero Trust Network Access (ZTNA), unified Data Loss Prevention (DLP) across endpoint, cloud and network, Remote Browser Isolation (RBI) and Firewall-as-a-Service, making McAfee one of the only vendors in the industry that solves the network security puzzle of the SASE framework. With the inclusion of MVISION Cloud Firewall, McAfee Enterprise customers can now utilize a unified security solution to inspect any type of traffic destined to the cloud, web, or corporate networks, while securing the sensitive assets and users across every location.

The current business transformation and remote workforce expansion require zero trust access to corporate resources, with end-to-end data security and continuous risk assessment to protect applications and data across all locations – public clouds, private data centers, and user devices. MVISION Private Access is the industry’s first truly integrated Zero Trust Network Access solution that enables blazing fast, granular “Zero Trust” access to private applications and provides best-in-class data security with leading data protection, threat protection, and endpoint protection capabilities, paving the way for accelerated Secure Access Service Edge (SASE) deployments.
We are currently operating in a world where enterprises are borderless, and the workforce is increasingly distributed. With an increasing number of applications, workloads and data moving to the cloud, security practitioners today face a wide array of challenges while ensuring business continuity, including:
Cloud-based Software-as-a-Service (SaaS) application adoption has exploded in the last decade, but most organizations still rely heavily on private applications hosted in data centers or Infrastructure-as-a-Service) IaaS environments. To date Virtual Private Networks (VPN) have been a quick and easy fix for providing remote users access to sensitive internal applications and data. However, with remote working becoming the new normal and organizations moving towards cloud-first deployments, VPNs are now challenged with providing secure connectivity for infrastructures they weren’t built for, leading to bandwidth, performance, and scalability issues. VPNs also introduce the risk of excessive data exposure, as any remote user with valid login keys can get complete access to the entire internal corporate network and all the resources within.
Enter Zero Trust Network Access, or ZTNA! Built on the fundamentals of “Zero Trust”, ZTNAs deny access to private applications unless the user identity is verified, irrespective of whether the user is located inside or outside the enterprise perimeter. Additionally, in contrast to the excessive implicit trust approach adopted by VPNs, ZTNAs enable precise, “least privileged” access to specific applications based upon the user authorization.
We are pleased to announce the launch of MVISION Private Access, an industry-leading Zero Trust Network Access solution with integrated Data Loss Prevention (DLP) and Remote Browser Isolation (RBI) capabilities. With MVISION Private Access, organizations can enable fast, ubiquitous, direct-to-cloud access to private resources from any remote location and device, allow deep visibility into user activity, enforce data protection over the secure sessions to prevent data misuse or theft, isolate private applications from potentially risky user devices, and perform security posture assessment of connecting devices, all from a single, unified platform.
Here are the key capabilities offered by ZTNA to provide secure access for your remote workforce:
Though ZTNAs are frequently promoted as VPN replacements, nearly all ZTNA solutions share an important drawback with VPNs – lack of data awareness and risk awareness. First-generation ZTNA solutions have categorically focused on solving the access puzzle and have left data security and threat prevention problems unattended. Considering that ubiquitous data awareness and risk assessment are the key tenets of the SASE framework, this is a major shortcoming when you consider how much traffic is going back and forth between users and private applications.
Moreover, the growing adoption of personal devices for work, oftentimes connecting over unsecure remote networks, significantly expands the threat surface and increases the risk of sensitive data exposure and theft due to lack of endpoint, cloud and web security controls.
Addressing these challenges requires ZTNA solutions to supplement their Zero Trust access capabilities with centralized monitoring and device posture assessment, along with integrated data and threat protection.
MVISION Private Access, from McAfee Enterprise, is designed for organizations in need for an all-encompassing security solution that focuses on protecting their ever-crucial data, while enabling remote access to corporate applications. The solution combines the secure access capabilities of ZTNA with the data and threat protection capabilities of Data Loss Prevention (DLP) and Remote Browser Isolation (RBI) to offer the industry’s leading integrated, data-centric solution for private application security, while utilizing McAfee’s industry-leading Endpoint Security solution to derive deep insights into the user devices and validating their security posture before enabling zero trust access.
MVISION Private Access allows customers to immediately apply inline DLP policies to the collaboration happening over the secure sessions for deep data inspection and classification, preventing inappropriate handling of sensitive data and blocking malicious file uploads. Additionally, customers can utilize a highly innovative Remote Browser Isolation solution to protect private applications from risky and untrusted unmanaged devices by isolating the web sessions and allowing read-only access to the applications.

We are in the midst of digital transformation to the cloud – these cloud services fuel transformative projects for businesses, empowering employees with powerful tools to do their jobs better and more efficiently. This cloud transformation has meant that a large portion of enterprise data now resides and is being accessed outside of the network perimeter and beyond the reach of traditional data security controls.
MVISION Unified Cloud Edge is the SASE security fabric between an organizations’s workforce and their resources that enables fast direct-to-internet access by eliminating the need to route traffic through their data center for security. Data and threat protection are performed at every control point in a single pass to reduce the cost of security and simplify your management.
Sensitive data uploaded to CRM has also put the service on the radar of IT security teams. Based on the Market share report Microsoft Dynamics 365 is amongst the top CRM vendors
Data in Dynamics 365 represents anything from proprietary business information to sensitive customer data. The high volume and value of this data have made Dynamics 365 security a top priority for companies embarking on cloud security projects.
Microsoft provides a host of security features for enterprise customers at the infrastructure and software level, but customers default lack many controls around data and user account security. For example, only 36 percent of cloud customers say they can enforce data loss prevention in the cloud. These are key security controls for organizations using Dynamics 365, especially those who upload regulated data to the service.
MVISION Cloud for Dynamics 365, part of McAfee’s Unified Cloud Edge offering is a comprehensive solution, which allows enterprises to enforce security controls for data in Dynamics 365. It addresses four areas of Dynamics security:
By applying cloud DLP policy you can find any sensitive info stored in Dynamics entity in near real-time. Configure via UI the entities where you know sensitive content is posted by the user and do near real time DLP. Also, you can integrate your Endpoint DLP engine policy and use the single console of MVISION to leverage the DLP policy defined on Dynamics entities. In addition, before the Auditor finds any sensitive information stored in data at rest, you can run on-demand scans on Dynamics 365 entities/attachments to ensure there is no sensitive data in Dynamics entities. MVISION Cloud Compliance scan applies to entities (structured data) and attachments (unstructured data) in Dynamics. Data privacy can save organizations from massive compliance fines, a negative public image, and loss of customer trust. Dynamics 365 data privacy is just as important as security, MVISION Cloud compliance scan ensures GDPR compliance for data at rest. In all cases whenever out of compliance is found, then raise incidents and takes remedial action for complete visibility. Malware scan to detect malware on any Dynamics 365 attachments if there is Malware. This scan could be Near Real-Time and also could be on data at rest.
MVISION Cloud for Dynamics 365 can act as an additional control point between enterprise users and the cloud to provide enhanced analytics into cloud usage, detect threats from insiders, compromised accounts, and privileged users, enforce compliance policies with DLP, and contextual access controls. Additionally, detecting intentional or inadvertent threats from employees or third parties, enforcing granular access controls based on parameters such as role, device, data, and location, and enforcing DLP policies.
Finally, the MVISION platform provides benefits that a single-point solution for one cloud service cannot satisfy. A single point for cloud control removes gaps in policy enforcement. Visibility into all cloud traffic allows MVISION to correlate activity occurring across multiple cloud services, identifying high-risk users and cloud-to-cloud threats. And MVISION offers integrations with on-premises security tools to extend existing security policies to the cloud and feed cloud threats into SIEM solutions. Consolidating all cloud security data in one tool is the best way to capture a holistic view of cloud risk, in a snapshot and as it changes over time.
Moving to the cloud does not have to be a trade-off between business results and security. Improved security in the cloud is a reality for companies that have embraced a cloud-native security approach. Using MVISION Cloud for Dynamics 365 can make data safer than ever before while empowering business teams to become more efficient and dynamic.

As you know, McAfee Enterprise’s MVISION Unified Cloud Edge (UCE) was the first of all the SASE vendors to implement the MITRE ATT&CK Framework for Cloud last year. An important aspect of Gartner’s SASE Framework is the ability for effective Threat Protection and Resolution in the Cloud. MVISION UCE takes this to the next level – the product takes a multi-layered approach to cloud threat investigation that can speed your time to detect adversary activity in your cloud services, identify gaps, and implement targeted changes to your policy and configuration.
As a quick refresher, the MITRE Att&CK Matrix represents the relationship between attacker Tactics and Techniques:
This Dashboard is available within the MVISION Cloud console by accessing the Dashboards > MITRE Dashboard link
Ever since the launch of this truly differentiated product offering, we have seen a tremendous amount of interest and adoption of this feature within our existing customers. Over the past few months, we have continued to make significant enhancements as part of our MITRE Dashboard.
In this post, I shall summarize some of the significant highlights that we have introduced in the past few releases:
The Executive Summary displays an at-a-glance view of the current count of Threats, Anomalies, Incidents, types of incidents, and Detected Techniques with severity.
To suit the needs of the different teams that would be using the MVISION Dashboard, we now have the ability to filter the MITRE Dashboard by using a variety of facets:
When an incident is detected for a technique in MVISION Cloud, a severity is computed. The detected techniques are categorized based on the severity of the incidents. Each detected technique is interactive and leads to more detailed explanations.
To view the details of the detected techniques:
With McAfee Enterprise, threat investigation isn’t just for one environment – it is for all of your environments, from cloud to endpoint to your analytics platforms. With MVISION Cloud, MVISION EDR, and MVISION Insights, your enterprise has an extended detection and response (XDR) platform for the heterogenous attacks you face today.

Security professionals and technologists old enough to remember renting movies at Blockbuster on Friday nights likely also remember a time when the internet was a new phenomenon full of wonder and promise. These same individuals probably view it through a more skeptical lens seeing it now as a cesspool of malware and great risk. It’s also widely understood that no web security solution can offer perfect protection against the metaphorical minefield that is the internet. This last statement, however, is being challenged by a new technology that is grasping at the title of perfect web security. This mythical technology is Remote Browser Isolation, or RBI, and it can be argued that it does, in fact, provide its users with invincibility against web-based threats.
Remote Browser Isolation changes the playbook on web security in one very fundamental way: it doesn’t rely on detecting threats. When a user tries to browse to a website, the RBI solution instantiates an ephemeral browser in a remote datacenter which loads all the requested content. The RBI solution then renders the website into a dynamic visual stream that enables the user to see and safely interact with it.
Figure 1: How Remote Browser Isolation works.
User behavior can be controlled at a granular level, preventing uploads, downloads, and even copy & paste using the local clipboard. When properly configured, absolutely none of the content from the requested site is loaded on the local client. For this reason, it can be argued that it’s literally impossible for malware to be delivered to the local client. Of course, the RBI solution’s ephemeral browser instance may be compromised, but it will be fully isolated from the organization’s valuable assets and data, rendering the attack harmless. As soon as the user closes their local browser tab, the ephemeral browser is destroyed.
The value of this cannot be overstated. The world is increasingly conducting its affairs through web browsers, and the challenge of detecting threats continues to increase at an exponential rate. While there is great efficacy and value in the threat intelligence and malware detection capabilities of web security solutions today, the “cat & mouse” game being played with cybercriminals means that they’re simply never going to offer perfect protection. Attackers often use zero-day threats coupled with domains registered perhaps within the past few minutes to compromise their victims, and these methods will too often succeed in circumventing any detection-based security measures. The game-changing efficacy of RBI and the fact its inception was actually more than 10 years ago should bring an obvious question to mind – If it’s so great, why doesn’t every organization in the world use RBI today? There are a few relevant answers to this, but one rises above all the rest: cost.
RBI’s method of instantiating remote web browsers for all users precludes the possibility of any implementation that is not expensive to deliver. Consider the size of a modern enterprise, the number of users, the number of web browser tabs an average user keeps open, and then consider the amount of memory and CPU consumed by each of those tabs. To mirror these resources in a remote datacenter will always be a costly proposition. For this reason, many RBI solutions on the market today may literally consume the entire security budget allocated for each licensed user. As prevalent as web-based threats are today and as effective as RBI’s protection may be, no security organization can dedicate most or all of their security budget to a single technology or even a single threat vector.
To better understand the cost problem and how it may be solved, let’s take a closer look at the two most common use cases for RBI. The first and most common use case is handling uncategorized sites or sites with unknown risk, known as selective isolation. As mentioned before, attackers will often use a site that was registered very recently to deliver their web-based threats to victims. Therefore, organizations often want to block any site that has not been categorized by their web security vendor. However, the problem is that many legitimate sites can be uncategorized resulting in unnecessary blocking that may impact business. Managing such a policy is very tedious, and the user experience tends to suffer greatly. RBI is an ideal solution to this problem where you can grant users access to these sites while maintaining a high level of security. This situation calls for a selective use of RBI where trusted sites are filtered through more traditional means while only the unknown or high-risk sites are isolated.
The other common need for RBI is various groups of high-risk users. Consider C-level executives who have access to highly sensitive information relating to business strategies, intellectual property, and other information that must remain private. Another common example is IT administrators who have elevated privileges that could be devastating if their accounts were compromised. In these scenarios, organizations may look to isolate all of the traffic for these users including even sites that are trusted. Typically, this full isolation approach is reserved for only a subset of users who pose a particularly high risk if compromised.
In light of these two use cases, selective isolation and full isolation, let’s take a closer look at the cost of this invincibility-granting technology. Let’s consider a hypothetical organization, Brycin International, who has a total of 10,000 users. Brycin has identified 400 users who either have access to critical data or have elevated permissions and therefore require full-time isolation. We will assume a street price of $100 per user for full time isolation totaling $40,000 for these users. This seems like a reasonable cost considering the elevated risk a compromise would represent for any one of these users. Brycin would also like to leverage selective isolation for the rest of the user population, or 9,600 users. Some solutions may require purchasing a full license, but most offer a discounted license for selective isolation. We will assume a generous discount of 60%, resulting in a total cost of $40 per user or $384,000 for the rest of the organization. This gives us a total price tag of $424,000 for Brycin, or an average cost of $42.40 per user.
Not only is this a steep cost for our 10,000-user enterprise, but the cost does not at all align with the value or the cost to deliver the solution. The 9,600 selective isolation users may represent 96% of the user population, but when you consider the fact that only a small percentage of their web traffic will actually be isolated – state-of-the-art web threat security stacks can detect as much as 99% of all threats, leaving 1% of all traffic to be isolated – they generate perhaps less than 20% of the isolated web traffic. The full isolation users, while a minority of the license count, will represent the bulk of the isolated web traffic – a little more than 80%. However, despite the fact that selective isolation users are responsible for such a small share of all isolated traffic and given the generous 60% discounted licensing, they are still by far the largest expense at over 90% of the total solution cost! This ratio of cost to value simply will not align with the budget and goals of most security organizations.
Figure 2: The disproportionate relationship between RBI users, traffic load, and solution cost.
McAfee Enterprise has now upended this unfortunate paradigm by incorporating remote browser isolation technology natively into our MVISION Unified Cloud Edge platform. McAfee Enterprise offers two licensing options for RBI: RBI for Risky Web and Full Isolation. RBI for Risky Web uses an algorithm built by McAfee Enterprise to automatically trigger browser isolation for any site McAfee Enterprise determines to be potentially malicious. This is designed to address the most common use case, selective isolation, and it is included at no additional cost for any Unified Cloud Edge customer. Additionally, Full Isolation licenses can be purchased as an add-on for any users that require isolation at all times. These Full Isolation licenses allow you to create your own policy dictating which sites are isolated or not for these users.
Now, let’s revisit Brycin International’s cost to deliver enterprise-wide RBI if they chose McAfee Enterprise. As we saw earlier, despite the fact the selective isolation users generated less than 20% of the traffic, they represented over 90% of the total cost of the solution. With McAfee Enterprise’s licensing model, these users would not require any additional licenses at all, reducing this cost to zero! Now, Brycin only has to consider the Full Isolation add-on licenses for their 400 high-risk users, or $40,000 – this is now the entire cost for the enterprise-wide RBI deployment. While $100 per user still may exceed the per-user security budget for Brycin, it is now diluted by the total user population, reducing the per-user cost of the RBI deployment from $42.40 to only $4. This is a tremendous reduction in cost for equal or greater value, making RBI much more likely to fit into Brycin’s budget and overall security plans.
This may beg the question, “How can McAfee Enterprise do this?” In short, as one of the most mature security vendors in the world, McAfee Enterprise has the most powerful threat intelligence and anti-malware capabilities in the market today. McAfee Enterprise’s Global Threat Intelligence service leverages over 1 billion threat sensors around the world reducing the unknowns to an extremely small fraction of all web traffic. In addition, its heuristics-based anti-malware technology is able to detect many zero-day malware variants. More uniquely, the Gateway Anti-Malware engine offers inline, real-time, emulation-based sandboxing using behavioral analysis to identify never-before seen threats based on their behavior. After analyzing the combined effectiveness of these technologies, we found that only a small percentage of web traffic could not be confidently identified as either safe or malicious – roughly 0.5%. This made the cost of delivering selective RBI for Risky Web something that could be easily absorbed without any additional cost to our customers.
Remote Browser Isolation is an absolute paradigm shift in how we can protect our most critical assets against web-based threats today. While the benefits are tremendous, cost has been a significant barrier preventing this powerful defense from becoming a ubiquitous technology. McAfee Enterprise has broken down this barrier by leveraging our superior threat intelligence to reduce the cost of delivering RBI and then passing this savings on to our customers.
Remove the risk and enjoy worry-free web browsing with McAfee’s RBI.

Attackers have made it known that Microsoft is clearly in their cross hairs when it comes to potential targets. Just last month the US Justice Department disclosed that Solorigate continues to comprise security when they confirmed over 80% of Microsoft email accounts were breached across four different federal prosecutors offices. In August Microsoft released another security patch (the second of two) for PrintNightmare, which allows remote attackers system level escalation of all Windows clients and servers. Since Microsoft still has the dominate market share for desktop OS, email/office services, along with the second largest market share in cloud computing, any security vulnerability found within the Microsoft ecosystem has cascading effects across the board.
Based on this, we wanted to let our customers know our response to the latest Microsoft security vulnerability. On August 12, Microsoft confirmed a security vulnerability dubbed ChaosDB whereby attackers can download, delete, or modify all data stored within the Azure Cosmos DB service. In response to the vulnerability Microsoft has since disabled the feature that can be exploited and notified potentially affected customers. However, according to the research team that identified the vulnerability they believe the actual number of customers affected is much higher and has the potential to expose thousands of companies dating back to 2019.
Cosmos DB is Microsoft’s fully managed NoSQL database service hosted on Azure which boasts customers such as Mars, Mercedes Benz, and Chipotle. The ChaosDB vulnerability affects customers that use the Jupyter Notebook feature. This built-in feature allows customers to share data visualizations and narrative text based on the data stored in Cosmos DB. Unfortunately, the Jupyter Notebook feature has been enabled by default for customers since February 2021, and fixing the vulnerability is no easy task. Because the vulnerability exposes public keys that can be used to access other Cosmos databases, the resolution requires that customers manually rotate their Cosmos DB primary keys – which are typically long-lived keys and used across multiple services or applications.
For customers using Cosmos DB, we highly recommend following Microsoft’s guidance and rotate their keys, but we also recognize that business can’t stop and unless you’ve automated key rotation, that task may take time and coordination across multiple teams. This blog will help provide some assistance on how one of our newest services can help identify and mitigate ChaosDB.
MVISION Cloud Native Application Protection Platform (CNAPP) is a new service we launched this year that provides complete visibility and security into services and applications built on top of cloud native solutions. MVISION CNAPP helps customers secure the underlying platform like Amazon Web Services (AWS), Microsoft Azure, and Google Cloud used to build applications but also provides complete build and runtime protection for applications using virtual machines, Docker, and Kubernetes.
As part of this service, MVISION CNAPP has a feature called the custom policy builder. The custom policy builder is a great way for customers to audit services across their entire cloud environment in real time to identify risky configurations but can also be used to curate a specific policy to the customer’s unique environment based on several API properties.
How does the custom policy builder work? Once MVISION CNAPP is connected to a customer’s AWS, Azure, or GCP account, the custom policy builder will list all the supported services within each cloud platform. Along with all the supported services, the custom policy builder will also list all the available API attributes for each of those services – attributes that customers can use as triggers for creating security incidents and automatic responses. A good example of the capability would be “if MVISION CNAPP identifies a public Amazon S3 bucket, performs a scan to on the bucket objects to identify any sensitive data and alerts teams via a SNS notification.” When new vulnerabilities like ChaosDB hit the wire, the custom policy builder is purpose built to help customers identify and understand their risk to anything new.
So how can CNAPP help identify if you’re at risk for ChaosDB? Essentially, you’ll want to answer three questions to understand your risk:
To find answers to these questions, I’ll show how you can create several custom policies using the MVISION CNAPP custom policy builder, but you can combine and mix these rules based on your needs.
In the first example, I’m going to answer the first two questions to see if we’re running Cosmos DB and if the service has unrestricted network access. Under the MVISION CNAPP menu I’ll click on Policy | Configuration Audit | Actions | Create Policy. From there I’ll give my policy a name and select Microsoft Azure | Next. The custom policy builder will automatically prepopulate all the available services in Azure when I click on Select Resource Type. Select Azure Cosmos DB and the custom policy builder will now show me all the available API attributes for that service. Start typing for the string of properties.publicNetworkAccess with a statement of equals to Enabled with a severity level you assign. Click Test Rule and the custom policy builder will check if you’re running any Cosmos DBs that allow access from any source.
Figure 1: Custom Policy Builder Screenshot
If the results of the custom policy show any incidents where Cosmos DB has unrestricted access, you’ll want to immediately change that setting by Configuring an IP firewall in Azure Cosmos DB.
Now let’s see if we have any Cosmos databases where we haven’t set firewall rules. These rules can be based on a set of IP addresses or private end points and should have been set when you created the DBs, but let’s confirm. You’ll follow the same steps as before but select the following criteria for the policy using AND statements:
Figure 2: Custom Policy Builder Screenshot 2
If you see any results from the custom policy, you’ll want to review the IP address and endpoints to make sure you’re familiar with access from those sources. If you’re not familiar with those sources or the sources are too broad, follow Configuring an IP firewall in Azure Cosmos DB to make the necessary changes.
Finally, let’s show how MVISION CNAPP can audit to see what is possible if your keys were exposed. In general, database keys are issued out to applications so they can access data. Rarely would you issue keys to make configuration changes or write changes to your database services. If you granted keys that can make changes, you may have issued an overly permissive key. Eventually you’ll want to regenerate those keys, but in the meantime let’s identify if the keys can make write changes.
We’ll follow the same procedure as before but use the properties.disableKeyBasedMetadataWriteAccess equals to false
Figure 3: Custom Policy Builder Screenshot 3
Like in the previous examples, if you find any results here that show you’ve issued keys that can make write changes, you’ll want to disable the feature by following Disable key based metadata write access.
Our custom policy builder is just one of the many features we’ve introduced with MVISION CNAPP. I invite you to check out the solution by visiting http://mcafee.com/CNAPP for more information or request a demo at https://mcafee.com/demo.

After more than a century of technological innovation since the first units rolled off Henry Ford’s assembly lines, automobiles, and transportation bear little in common with the Model T era. This evolution will continue as society finds better ways to achieve the outcome of moving people from point A to point B.
While Secure Web Gateways (SWGs) have operated on a far more compressed timetable, a similarly drastic evolution has taken place. SWGs are still largely focused on ensuring users are protected from unsafe or non-compliant corners of the internet, but the transition to a cloud and remote-working world has created new security challenges that the traditional SWG is no longer equipped to handle. It’s time for the next generation of SWGs that can empower users to thrive safely in an increasingly decentralized and dangerous world.
The SWG actually started out as a URL filtering solution that enabled organizations to ensure that employees’ web browsing complied with corporate internet access policy.
URL filtering then transitioned to proxy servers sitting behind corporate firewalls. Since proxies terminate traffic coming from users and complete the connection to the desired websites, security experts quickly saw the potential to perform more thorough inspection than just comparing URLs to existing blacklists. By incorporating anti-virus and other security capabilities, the “Secure Web Gateway” became a critical part of modern security architectures. However, the traditional SWG could only play this role if it was the chokepoint for all internet traffic, sitting at the edge of every corporate network perimeter and having remote users “hairpin” back through that network via VPN or MPLS links.
The transition to a cloud and remote-working world has put new burdens on the traditional perimeter-based SWG. Users can now directly access IT infrastructure and connected resources from virtually any location from a variety of different devices, and many of those resources no longer reside within the network perimeter on corporate servers.
This remarkable transformation also expands the requirements for data and threat protection, leaving security teams to grapple with a number of new sophisticated threats and compliance challenges. Unfortunately, traditional SWGs haven’t been able to keep pace with this evolving threat landscape, resulting in an inefficient architecture that fails to deliver the potential of the distributed workforce.
Just about every major breach now involves sophisticated multi-level web components that can’t be stopped by a static engine. The traditional SWG approach has been to coordinate with other parts of the security infrastructure, including malware sandboxes. But as threats have become more advanced and complex, doing this has resulted in slowing down performance or letting threats get through. This is where Remote Browser Isolation (RBI) brings in a paradigm shift to advanced threat protection. When RBI is implemented as an integral component of SWG traffic inspection, it can deliver real-time, zero-day protection against ransomware, phishing attacks, and other advanced malware so that even the most sophisticated threats can’t get through, without hindering the browsing experience.
Another issue with most traditional SWGs is that they aren’t able to sufficiently protect data as it flows from distributed users to cloud apps, due to lacking advanced data protection and cloud app intelligence. Without Data Loss Prevention (DLP) technology that is advanced enough to understand the nature of cloud apps and to keep up with evolved safety demands, organizations can find data protection gaps in their SWG solutions that keep them vulnerable to risks.
Finally, there is the question of cloud applications. While cloud applications operate on the same internet as traditional websites, they function in a fundamentally different way that traditional SWGs simply can’t understand. Cloud Access Security Brokers (CASBs) are designed to provide visibility and control over cloud applications, and if the SWG doesn’t have access to a comprehensive CASB application database and sophisticated CASB controls, it is effectively blind to the cloud. It’s only a cloud-aware SWG with integrated CASB functionality that can extend data protection to all websites and cloud applications, empowering organizations and their users to be better protected against advanced threats.
A next-gen SWG should help simplify the implementation of Secure Access Service Edge (SASE) architecture and help accelerate secure cloud adoption. At the same time, it needs to provide advanced threat protection, unified data control, and efficiently enable a remote and distributed workforce.
Here are some of the use cases:
SWGs have clearly come a long way from just being URL filtering devices to the point where they are essential to furthering the safe and accelerated adoption of the cloud. But we need to push the proverbial envelope a lot further. Digital transformation demands nothing less.
The post What to Expect from the Next Generation of Secure Web Gateways appeared first on McAfee Blog.
Many people are excited about Gartner’s Secure Access Service Edge (SASE) framework and the cloud-native convergence of networks and security. While originally proposed as fully unified architecture delivering network and security capabilities, the reality soon dawned that enterprise transition to a complete SASE model would be a decade long journey due to factors such as existing investments, operational silos (customer), and vendor consolidation. Consequently, Gartner introduced a new two-vendor approach to SASE that brought together a highly converged WAN Edge Infrastructure platform alongside a highly converged security platform – known as Security Service Edge (SSE).
Figure 1: SASE convergence.
SSE brings together Secure Web Gateway (SWG), Cloud Access Security Broker (CASB), and Zero Trust Network Access (ZTNA) to secure access to the web, cloud services, and private applications, resulting in reduced risk, cost and complexity. McAfee Enterprise has long been a proponent of this approach: we embarked on a project to build the industry’s best SASE security solution over three years ago, introduced our MVISION Unified Cloud Edge solution in early 2020, and have since continued to innovate and set the standard for the Security Service Edge space.
The fundamental problem that SSE sets out to solve is that enterprises must adequately secure their personnel and their data. This became increasingly difficult as digital transformation spurred widespread cloud adoption and empowered remote and mobile workers. Just a few short years ago we would talk about remote access for short periods of time due to travel, and typically for a small proportion of the workforce. Today we speak in the context of COVID-19 and a vast, permanent “Work From Anywhere” (WFA) cultural shift. Supporting this shift is an accelerated migration into the cloud, where the vast majority of workloads and applications will soon reside.
All of this has taken down the walls that formed the perimeter we relied on heavily in the past. Today our people and our data are outside of that perimeter but inside of cloud applications. Cloud applications run from many locations, sometimes around the globe. Yet our objectives must remain the same. We still must secure our people, we must secure our devices, and we must secure our data on any device, at any time, using any service.
Secure web gateways were one of the gatekeepers to the old perimeter, fundamentally appliances that existed at the border of a network. Cloud access security brokers (CASB) were fundamentally built to secure the inside of cloud services. Virtual Private Networks (VPNs) enabled you to securely interconnect offices and remote users onto a single network. Managing these technologies separately became increasingly problematic as the boundaries between networks, the web, and the cloud began to blur. Organizational policies and compliance requirements must be translated to the administrative setup of a specific vendor’s management consoles. At first pass, this results in more errors in the implementation of these policies. Maintenance is difficult as policy changes must be rolled out and implemented within multiple vendor management interfaces. And when you position these traditional technologies against the problem statement of a “perimeterless” world, they fail. The logical answer to these problems is to converge these technologies together and bring them to the cloud.
For more than 3 years, McAfee Enterprise has invested deeply into a unified policy framework. We’ve unified threat engines, data engines. We’ve built a unified user experience and unified administrative experience to deliver against that promise of cloud native security.
A closely integrated SSE infrastructure can address the management challenges of setting up policies in multiple vendor management interfaces by deeply integrating security controls to reduce overhead, complexity, and cost, while increasing performance. But looking at the competitive landscape, this has proven to be easier said than done. Many fall short with it comes to securing data within the cloud, but McAfee Enterprise’s industry-leading Multi-Vector Data Protection capabilities make it incredibly easy to keep data safe no matter where it resides, with unified data classification, policy enforcement, and incident management.
Figure 2: McAfee Enterprise Multi-Vector Data Protection.
Other vendors grew up in the cloud but fall short when it comes to connecting to the private resources all large enterprises still use today. Some vendors are attempting to build-out the entire SSE product set from scratch, perhaps as part of a larger SASE offering. Most of the functions present baseline functional capability and the considerable instability of a complex and very new product.
McAfee Enterprise has planned and executed a strategy for several years that takes MVISION Unified Cloud Edge’s complete set of SSE converged security services and then tie them closely to other highly integrated network services such as those offered by SD-WAN vendors to implement SASE. This approach enables most large enterprises the ability to leverage the majority of the technology partners they have to pull a SASE architecture together using much of the technology infrastructure they already have in place.
Figure 3: Enable secure access to web, cloud, and private apps with MVISION Unified Cloud Edge.
The increased efficiency of an integrated environment reduces the investment in administration, enhances the precision of policy enforcement, and improves the speed with which security control processes can be applied to data and activity in one single pass, improving security efficiency and efficacy. This earlier published blog demonstrates how our integration of Remote Browser Isolation (RBI) greatly improves security protection in a seamless, cost-effective manner.
Figure 4: MVISION Unified Cloud Edge threat protection stack with integrated Remote Browser Isolation.
The convergence and integration of cloud security technologies such as SWG, CASB, ZTNA, DLP, RBI and FWaaS substantially enhance operations, reduce cost, minimize errors, and enable more precise enforcement of organizational policy and management. Expenses are lower as experts in the administration and management of separate security controls are no longer required.
In conclusion, McAfee Enterprise has delivered the best and most rapid path to a comprehensive integrated SSE offering available in the market. Our Unified Cloud Edge (UCE) architecture completes that vision of unified and completely integrated policy management today. MVISION UCE is the security fabric that delivers data and threat protection to any location so you can enable fast and secure direct-to-internet access for your distributed workforce. This results in a transformation to a cloud-delivered SSE that converges with connectivity to reduce cost and complexity while increasing the speed and flexibility of your workforce.

Becoming a cloud first company is an exciting and rewarding journey, but it’s also fraught with difficulties when it comes to securing an entire cloud estate. Many forwarding-thinking companies that have made massive investments in migrating their infrastructure to the cloud are facing challenges with respect to their cloud-native applications. These range from inconsistent security across cloud properties to lack of visibility into the public cloud infrastructure where cloud-native applications are hosted—and more. All of these issues can create vulnerabilities in a sprawling attack surface that can be potentially exploited by cybercriminals.
Legendary Entertainment is a global media company with multiple divisions including film, television, digital studios, and comics. Under the guidance of Dan Meacham, VP of Global Security and Corporate Operations and CSO/CISO, the multi-billion dollar organization transitioned from on-premises data centers to the cloud in 2012.
Meacham points out that it’s been a source of great pride for his security and IT teams to always be “on top of the latest and greatest” technology trends—and migration to the cloud is no exception. That’s why his interest was sparked when he learned about the rollout of the MVISION security product line early in the migration process. Its cloud-native, open architecture was exactly the right fit for Legendary Entertainment’s environment.
As a cloud-first organization, Legendary Entertainment encountered challenges that are common to many companies that have migrated their workloads, applications, and data assets to the cloud. At first, the organization attempted to rely on security services natively provided by the individual cloud service providers: Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform (GCP), and Wasabi for cloud storage. As Meacham notes, “The security from one vendor doesn’t trickle over to the others. They all have different security controls, so our cloud security was not uniform, and security management was complicated.”
In their disparate multicloud environment spanning several cloud service providers, it became time-consuming and difficult to monitor and assess the security posture of applications and workloads, such as which systems needed patching or contained critical vulnerabilities.
With multiple management consoles required for its many cloud environments, applying and enforcing uniform security policy across their cloud estate was nearly impossible without investing a lot of time, effort, and resources.
Another problem in Legendary Entertainment’s early adoption of cloud-first was shadow IT, where employees or contractors enrolled in cloud collaboration platforms that were not authorized by IT. Although the shadow IT platforms were not connected to core systems, they made it more difficult to tightly monitor data which sometimes caused cloud-enabled applications to violate security policies. It is understandable that teams with a cloud-first mindset would embrace innovation and new collaborative experiences to accomplish goals faster. However, some of the shadow IT application has weak or no security controls – resulting the opportunities for external collaborator accounts to be compromised or have mis-managed privileges.
With high-profile data breaches in the entertainment industry in recent headlines, Legendary Entertainment was concerned about its level of risk and exposure, especially since it has valuable intellectual property such as scripts and marketing strategy plans for film releases among its holdings. The requirement for stronger security has been a boardroom-level conversation at digital media companies since the Sony Pictures hack and other vendor supply chain and workflow hacks. Attacks now extend beyond data leaks and can have far reaching business disruptions across an entire supply chain.
By deploying MVISION Cloud Native Application Protection Platform (MVISION CNAPP), Legendary Entertainment addressed all of these challenges at once. This unique solution prioritizes alerts and defends against the latest cloud threats and vulnerabilities. MVISION CNAPP combines granular application and data context with cloud security posture management and cloud workload protection in a single-console solution.
MVISION CNAPP provides Legendary Entertainment with broad and deep visibility across its entire infrastructure. It discovers all their cloud assets, including compute resources, containers, and storage and provides continuous visibility into vulnerabilities and security posture for applications and workloads running across multiple clouds.
Thanks to MVISION CNAPP, Meacham’s team can write, apply, and enforce security policies in a consistent fashion for the entire cloud estate. As Meacham points out, policy is continually checked so his team can correct any misconfigurations, disable services, or remove escalated privileges until corrections are made in alignment with internal compliance rules. And in many cases, the remediation can be automated internally in MVISION CNAPP or through workflow initiations.
“MVISION CNAPP gives me manageability and security uniformity for all our cloud platforms so that I can elevate the level of security and make it consistent across the board. Now that I have visibility into all our cloud assets from a high level, I can look at how current controls and configurations compare to our best practices, industry best practices, and to the best practices of peers who are using the same product. Without MVISION CNAPP, management is one to one, whereas with MVISION CNAPP, it’s one to many,” explains Meacham.
The Cloud Security Posture Management (CSPM) component of MVISION CNAPP provides Legendary Entertainment with on-demand scanning, which looks at all services used in the public cloud and checks their security settings against internal benchmarks. “This gives us a security posture score and provides feedback on what we can do to bring ourselves back into compliance,” observes Meacham. “If someone changes a configuration, we get an alert right away. And if it’s not in alignment with policy, we can roll it back to the previous settings. MVISION CNAPP also helps us remediate policy exceptions by clearly stating the risks, instances impacted, and the necessary step by step actions needed for resolution.”
MVISION CNAPP also ensures that Legendary Entertainment’s developers operate in a secure environment by alerting the security team when their actions violate security policies or increase the risk of a data breach. This effectively puts a halt to Shadow IT.
“MVISION CNAPP helps me keep my system administrators and developers accountable for what they are doing. We can make sure that they are consistent in how they execute, deploy, and build things. Configuration policies, on-demand scans, and different types of checks in MVISION CNAPP can help force that compliance. I am able to keep tabs on my developers to make sure they are operating according to these guidelines in any platform,” remarks Meacham.
MVISION CNAPP reduces risk associated with operating in the cloud, enabling Legendary Entertainment to run mission-critical applications and develop blockbuster movies such as “The Dark Knight Rises” and “Dune” securely across a heterogenous multicloud environment. The solution also enables contextual entitlements so that users can be identified and assigned selective access to and permissions for applications and resources based on the security profile of the devices they are using at any given time.
Legendary Entertainment leverages MVISION CNAPP’s data loss prevention (DLP) capabilities to monitor activity in cloud data stores in order to help prevent data breaches. Unusual or suspicious activity or unauthorized movement of data transit is tracked and flagged immediately by leveraging built-in UEBA capabilities.
“If I see 2,000 files change in 30 seconds, that’s a huge red flag indicating ransomware or some other type of attack. The solution’s monitoring tool detects suspicious behavior and immediately brings that to our awareness. If we see something like that happening on multiple platforms, we know that immediate action is required. The UEBA capability is invaluable for identifying external collaborators who may have compromised accounts, which we find on a regular basis.”

With the widespread adoption of hybrid work models across enterprises for promoting flexible work culture in a post pandemic world, ensuring critical services are highly available in the cloud is no longer an option, but a necessity. McAfee Enterprise’s MVISION Unified Cloud Edge (UCE) is designed to maximize performance, minimize latency, and deliver 99.999% SLA guaranteed resiliency, offering blazing fast connectivity to cloud applications from any location and causing no service degradation, even when the usage of cloud services spiked 600% during the COVID-19 pandemic, as reported in our Cloud Adoption and Risk Report (Work From Home Edition). This blog shares details on how MVISION UCE is architected to enable uninterrupted access to corporate resources to meet the demands of the hybrid workforce.
MVISION UCE, our data-centric, cloud-native Security Service Edge (SSE) security platform, derives its capabilities from McAfee Enterprise’s industry leading Secure Web Gateway and Enterprise Data Protection solutions. However, this is not a lift and shift of capabilities to the cloud, which would have made it prone to service outages and impossible to have the flexibility that is needed to meet the demands of SSE. Instead, the best of breed functionality was purposefully reconstructed for SSE, using a microservices architecture that can scale elastically, and built on a platform-neutral stack that can run on bare metal and public cloud, equally effectively. A hallmark of the architecture is that the cloud is a single global fabric where service instances are spread throughout the globe. Users automatically access the best instance of any service through policy configuration.
What other alternatives are out there? We have seen some cloud services replicated in each region of their presence. While this makes controlling resources and data simple, and keeps everything within a boundary, such an approach loses out on the flexibility needed to scale on demand and reduced latency on access. With UCE, each point of presence (POP) is part of the global fabric, yet at the same time, fully featured with all services housed within the POP. This avoids the need to send traffic back and forth between various services located at different locations, a phenomenon known as traffic hairpin.
By default, user traffic gets processed at the POP closest to their physical location, regardless of where the user may be. A user may work at their office in New York 90% of the time and travel to UK occasionally. When the user connects to MVISON UCE, they are connected to New York POP when they are at office, and the POP in London if they are in a UK hotel while traveling. This is a big advantage if you think about it. User’s traffic does not need to trombone from the hotel in UK, to the POP in New York and back to a server in London. MVISION UCE’s out-of-the-box traffic routing scheme favors low latency. This does not mean that the customer cannot override this policy and force the traffic to be processed at the New York POP. They might do so if there is a compliance need to process all traffic at a certain location. Many customers have a need to store logs in a certain geography even though traffic processing may occur anywhere on the globe. MVISION UCE architecture decouples log storage from traffic processing and lets the customer choose their log storage geography based on criteria that customers define.
One of the key considerations while choosing a SSE vendor would be how much latency the service adds to user’s requests. Significant latency can negatively affect user experience and could be a deterrent to product adoption. With 85 POPs strategically placed around the globe providing low latency access to customers, UCE POPs have direct peering with the biggest SaaS vendors like Microsoft, Google, Akamai, and Salesforce to further reduce latency. In addition, MVISION UCE POPs peer with many ISPs around the globe, enabling high bandwidth and low latency connectivity end to end, from the customer’s network to UCE and from UCE to the destination server.
With thousands of peering partners growing every day, over 70% of traffic served by MVISION UCE uses peering links in some geographies. The whitepaper, How Peering POPs Make Negative Latency Possible, shares details about a study conducted by McAfee Enterprise to measure the efficacy of these peering relationships. This paper is proof that UCE customers experience faster response times going through our POPs than they would usually get by going directly through their Internet Service Providers. UCE follows a living partnership model when it comes to peering, with thousands of peering relationships in production. We are committed to keeping the latency to a minimum.
You may be wondering what the secret sauce is for achieving a reliability of five 9s or higher in MVISION UCE. Several items play a crucial role in preventing unplanned service degradation.
At McAfee Enterprise, security is not an afterthought. From the start, the architecture was designed with zero trust in mind. Services are segmented from one another and follow the least privileged principle when resources need to be shared between services. Industry standard protocols and methodologies are used to enforce user and identity access management (UAM/IAM). Strong role-based access controls (RBAC) across the platform keep customer’s data separate and provide self-defense when a service is compromised. None of these features matter if the software is vulnerable. McAfee Enterprise follows one of the strictest Software Development Life Cycle (SDLC) processes in the industry to eliminate known vulnerabilities and threats in our software as it is written.
Another aspect of security that is gaining momentum these days is data privacy. This is at the forefront of all feature designs in MVISION UCE. Usually, data privacy means tokenization or anonymization of customer private data stored in MVISION UCE, be it logs or other metadata. At McAfee Enterprise, we strive to take this a step further. We do not want to retrieve private data from the customer environment if it can be avoided. For example, to evaluate a policy that involves customer premise data, UCE can offload the evaluation to a component on the customer premise. Case in point, McAfee Client Proxy (MCP) that is installed on user’s machine can perform a policy evaluation and avoid sending private data to the cloud. The McAfee Enterprise cloud leverages the results of the evaluation to complete the policy execution. Where this is not possible, private data is anonymized at the earliest entry point in the cloud to minimize data leaks.
Last but not the least, a chain is only as strong as its weakest link, and physical data center security must also be considered. Global partners are selected only after careful evaluation of their facilities and infrastructure that will host our data centers, while other vendors in this space are working with a larger set of less rigorously qualified regional partners to increase their presence. The McAfee Enterprise approach provides the necessary guard rails against supply chain attacks that our customers demand.
There are other architectural gems hidden within UCE and thus failing to mention them would make this article incomplete. First, the policy engine is exposed in the form of code with which the customer can construct complex policies without being constrained by what UI provides. If you are a user of MVISON UCE, you can see this in action by enabling “Code View” in the Web Policy tree. If you do not like the way policy nodes are ordered in the tree or the evaluations made by default, you can take complete control and process the traffic in any manner you wish. By the way, the policy is so flexible that one can write a policy to process traffic in one region and store logs in another region.
Second, policy evaluation can be distributed across various components which allows its evaluation at the earliest point in the network. This avoids hauling all traffic to the cloud to apply policy. For example, if a sensitive document needs to be blocked due to data protection rules, the DLP agent running on the user’s machine can block it instead of hauling the traffic to cloud for classification and blocking. This strategy reduces load on the cloud and consequently increases the scale at which we can process requests.
Lastly, all services are automated and require no manual intervention to provision a customer unlike other vendors that require a support ticket to provision some features. Independent of where your account has been provisioned and where your preferred UI console resides, polices that you author are stored in a global policy system that is synchronized to all POPs around the world, giving you the flexibility to process traffic anywhere in the world.
To conclude, all clouds are not built equally. Architecture of a cloud is a matter of choice and tradeoffs. MVISON UCE implements a global cloud and puts customers in the driver’s seat through programmatic policies, that are secure, scalable, and highly available.

Cloud Security Gateways (CSGs) are one of the hottest and most sought-after technologies in the market today, driven by the adoption of cloud services for business transformation and the acceptance of hybrid workforce policies. CSGs, also commonly known as Cloud Access Security Brokers (CASBs), are responsible for enforcing security policies to protect cloud-hosted corporate assets from advanced threats, while enabling seamless and secure access to these assets from any location and device.
We have witnessed an exponential growth in cloud usage in the past two years, primarily driven by remote workforce adoption. Based on the data collected by our research team from millions of connected McAfee Enterprise users across the globe, the overall usage of enterprise cloud services spiked by 50% across all industries, while the collaboration services witnessed an increase of up to 600% in usage. This led to an astonishing 630% increase in external attacks on the cloud accounts. Taking all these factors and trends into consideration, CSGs have become a highly essential element of any organization’s cloud security strategy, playing the most critical role for enabling data protection, threat prevention and compliance in the cloud.
McAfee Enterprise continues to innovate in the cloud security space with a laser-focused strategy towards empowering our customers with the best-in-class cloud security solution. MVISION Cloud, recognized as the industry’s leading CSG solution, has become a vital part of enterprise security, allowing organizations to safely migrate to the cloud while protecting their “crown jewels” – the data. A huge testament to our cybersecurity vision is the IDC MarketScape Worldwide Cloud Security Gateways 2021 Vendor Assessment (Doc # US48334521, November 2021), and we are proud to announce that McAfee Enterprise has been recognized as a leader in the report.
According to the report, “McAfee has a strong ecosystem of security solutions, including Secure Web Gateway, CSG, and endpoint security that it can integrate to enable customers in their data loss prevention, User Behavior Analytics, XDR, and threat prevention goals. McAfee has focused on providing robust protection and DLP, with the scale and speed necessary to support large user bases.”
McAfee Enterprise’s multi-vector data protection capabilities go beyond the cloud to uniquely discover and protect sensitive assets on managed endpoints, in-network shares, and on-premises databases, enabling full scope of data protection from device-to-cloud. The industry-leading data protection and threat protection capabilities are tightly integrated with a unified policy framework that allows policy enforcement, data classification and incident management from a centralized console, reducing the cost and complexity of managing hybrid IT deployments, while improving the user experience.

With the acceleration of cloud migration initiatives—partly arising the need to support a remote workforce during the pandemic and beyond—enterprises are finding that this transformation has introduced new operational complexities and security vulnerabilities. Among these are potential misconfigurations, poorly secured interfaces, Shadow IT (access to unauthorized applications), and an increasing number of connected devices and users. To navigate these challenges, enterprises are relying on managed service providers to monitor and protect their cloud environment.
To better serve its customers and secure its own environments, one global technology provider decided to expand its existing on-premises data loss protection (DLP) and web protection with a comprehensive and robust cloud security strategy based on solutions from the MVISION portfolio of solutions. Already a long-time user of McAfee Enterprise on-premises solutions, the global technology provider not only secured its internal cloud infrastructure consisting of more than 5,000 endpoints across over 30 locations worldwide, they also applied the same approach to the millions of endpoints they manage for more than 10,000 customers.
A primary objective for the global technology provider is securing data in the cloud in Software-as-a-Service (SaaS) applications (Microsoft Office 365, OneDrive, Salesforce, and others) and Infrastructure-as-a-Service (IaaS) platforms (Microsoft Azure, Amazon Web Services, Google Cloud Platform).
As a first step in its cloud journey, the global technology provider evaluated a number of cloud access security brokers (CASB) solutions. Ultimately, they decided to implement MVISION Cloud for AWS, Office 365, and Shadow IT. In addition to providing comprehensive visibility into cloud app usage, these solutions help with compliance; data loss prevention (DLP) by monitoring the movement of sensitive and confidential data content traveling to or from the cloud, within the cloud, and cloud to cloud; and detection and remediation of threats primarily through user and entity behavior analytics (UEBA).
But the global technology provider didn’t stop there. When we rolled out MVISION Unified Cloud Edge, the global technology provider tested it and enthusiastically adopted it. As defined by Gartner, MVISION Unified Cloud Edge is an industry-leading example of Secure Access Service Edge (SASE), a security framework that brings together network connectivity and security into a single, cloud-delivered solution that supports business transformation, edge computing, and workforce mobility.
The global technology provider has reaped multiple advantages from this implementation across its own internal environment and for its customers.
MVISION Unified Cloud Edge combines multiple capabilities under one umbrella: CASB functionality with web proxy and DLP with a single administrative hub, ePolicy Orchestrator® (ePO) for streamlined management.
MVISION Unified Cloud Edge capabilities and the ease of integration with the McAfee Enterprise ecosystem has made life easier for the global technology provider’s team, saving time and resources. Now they can set consistent policies from device to cloud and provide users with accelerated and secure access to the tools they use every day, such as Box, Dropbox, and others. As the information security operations manager points out: “A single management console reduces overhead as does being able to set policies that we can sync and apply to multiple data sources on multiple cloud solutions, without having to recreate rules.”
MVISION Unified Cloud Edge has also enabled the global technology provider to further boost its cloud data protection. For example, it can detect data that is improperly managed and stored. Now the organization can apply their existing on-premises data policies to the cloud. For example, they can prevent certain user behaviors that may put both corporate and customer cloud data at risk. These include copying data to cloud apps or USBs, printing it, taking screen captures, accessing risky websites, and uploading data to unauthorized websites.
To create a more secure internal environment, MVISION Unified Cloud Edge has been invaluable for the global security provider. They have a better handle on the applications that are being used across their company. The solution also provides risk scores for the cloud apps that are being used to help steer users away from Shadow IT and toward using only authorized apps. When employees propose new apps to help them do their jobs better, the IT security team can check the security of these apps against requirements and make any necessary modifications to ensure compliance.
“The Shadow IT CASB automatically blocks all cloud services that are deemed high risk, both at our on-premises Web Gateway and the built-in cloud web gateway manager. So, when users attempt to use an unsanctioned SaaS application, they see a message explaining that the app is not safe,” notes the information security operations manager.
The global technology provider also sells SaaS solutions to its clients. With MVISION Unified Cloud Edge, the global technology provider can protect data on any newly sanctioned SaaS applications at no extra cost.”
After a successful experience with McAfee Enterprise overall and specifically with the implementation of MVISION Unified Cloud Edge, the information security operation manager recommends the solution to any organization beginning or in the midst of migrating to the cloud.
“I would advise other companies thinking about their cloud transformation journey to seriously consider MVISION Unified Cloud Edge . . . It has a very user-friendly interface and does so much out of the box,” he asserts. “The level of granularity in policy setting lets you do things you don’t think possible or are much easier to accomplish than you realize. . . I don’t think any other vendor offers such a complete package.”

Companies continue to accelerate their digital transformation and hybrid work strategies with security remaining top of mind. For a growing number of enterprises, the solution has been the deployment of a Security Service Edge (SSE). Introduced as a market category by Gartner, per our view we believe SSE is the consolidation of Secure Web Gateway (SWG), Cloud Access Security Broker (CASB), and Zero Trust Network Access (ZTNA) within a single, cloud-delivered solution for securing access to web, cloud, and private applications from any corner of the world, mitigating user and cloud threats, and protecting sensitive cloud data at rest, in transit, or in use.

As of 28, January 2022, McAfee Enterprise is now the McAfee Enterprise SSE Portfolio.
The post McAfee Enterprise SSE: Named a Leader In 2022 Gartner Magic Quadrant for SSE appeared first on McAfee Blog.
Eighty-one percent of organizations told Gartner they have a multi-cloud strategy. As more organizations subscribe to cloud offerings for everything from hosted data centers to enterprise applications, the topology of the typical IT environment grows increasingly complex.
Now add the proliferation of hybrid work environments, the rapid ascendance of Internet of Things (IoT) devices, and an increasingly sophisticated and malicious cyber threat landscape, and it becomes immediately clear that protecting the integrity of your IT ecosystem is now a next-level problem.
In an unpredictable world, organizations everywhere are investing in initiatives that will infuse resilience into every aspect of their business, from finance to supply chains. To protect those investments, we believe they also need to invest in security resilience — the ability to protect your business against threats and disruption, and to respond to changes confidently so you can emerge even stronger.
This requires a next-level solution.
That’s why we’re building the Cisco Security Cloud — a global, cloud-delivered, integrated platform that secures and connects organizations of any shape and size. This cloud-native service is aimed at helping you protect users, devices and applications across your entire ecosystem. It will be a comprehensive, integrated set of services designed to scale with your business.
The Cisco Security Cloud will directly address these challenges by bringing together the depth and breadth of the Cisco security portfolio, and is:
We have been on this journey for years. We at Cisco Secure have been delivering key components of this security cloud, and those solutions already protect 840,000 networks, 67 million mailboxes and 87 million endpoints for customers the world over.
And today at the RSA Conference, we’re taking the next step by announcing our latest innovations addressing four key areas:
Today we are announcing Cisco’s turnkey Secure Access Service Edge (SASE) offering, Cisco+ Secure Connect Now, to simplify how organizations connect and protect users, devices, data, and applications, anywhere. Built on the Meraki platform, and available as a subscription, it unifies security and networking operations, as well as client connectivity and visibility into a single cloud-native solution, that can be set up in minutes.
Cisco is continuing to build out continuous trusted access solutions that that constantly verify user and device identity, device posture, vulnerabilities, and indicators of compromise. To evaluate risk after authentication, location information is critical, but we think GPS data is too intrusive. So today we are introducing a new patent-pending Wi-Fi Fingerprint capability (available in Public Preview this summer) to understand user location without compromising location privacy. We are also announcing new Session Trust Analysis capabilities to evaluate risk after login by using open standards for shared signals and events. We will unveil the first integration of this technology with a demo of Duo MFA and Box this week.
As organizations become more interconnected as ecosystems, and attacks become more sophisticated and personalized, it is no longer adequate to evaluate risk and threats generically across the industry. Organizations need deeper levels of advice and expertise. We are excited to launch the new Talos Intelligence On-Demand service, available now, offering custom research on the threat landscape unique to each organization. Talos Intelligence on Demand can assist with custom research, and brief our customers on the unique risks, threats, and mitigation strategies for their organizations.
Simplification is critical to driving better security efficacy. To that end, we are excited to announce the new Cisco Secure Client (available this summer), combining AnyConnect, Secure Endpoint, and Umbrella, to simplify how administrators and users manage endpoints. This follows the launch of the new cloud-delivered Secure Firewall Management Center, which unifies management for both cloud and on-premise firewalls.
There is more work to be done, of course, and today’s announcements at the RSA Conference are the latest advances in support of this vision. We will continue working on all aspects of the Security Cloud to improve our customers’ security resilience in the face of unprecedented change and increasing threats. Because next-level problems deserve next-level solutions.

What is it that customers truly want from their security? Is it simplicity? Robust protection? Agility and flexibility? Yes! In today’s uncertain world where new challenges are being thrown at IT teams each day, security must meet many diverse needs. At the end of the day, it’s about keeping the entire business resilient despite the chaos of the cyber world.
As hybrid work, the move to the cloud, and increasingly insidious threats all converge to create layers of complexity, security teams must be extra vigilant and ready for what’s next. They need a comprehensive, integrated security system whose various components share information and work together to pinpoint attacks and minimize organizational impact — without introducing undue friction.
With businesses, networks, clouds and devices becoming so interconnected, delivering next-level security to match the future of work is a formidable undertaking — one that few vendors are positioned to tackle. But thanks to our nearly 40-year heritage of providing and protecting a vast amount of the world’s networking infrastructure, Cisco is up for the challenge.
“At a moment’s notice, we were able to transition 80 percent of our workforce to be remote — and our company was never remote before. Because of our Cisco solutions, we were able to deploy everything and have people work well remotely with very minimal issues.”
— Joseph Rodriguez, Assistant Director of IT, Allied Beverage Group
Delivering security that is simple, powerful and resilient is something we’ve been executing on for years, yet it’s never been more critical than it is at this very moment. The month of June has afforded us the perfect opportunity to showcase exactly how we plan to keep our customers cyber resilient both now and in the future.
Read about the five dimensions of security resilience.
During the RSA Conference and Cisco Live, we announced our strategic plan for the Cisco Security Cloud, a global, cloud-delivered, integrated platform that secures and connects organizations of any shape and size. As we continue to move towards the Cisco Security Cloud vision, we recently unveiled several advancements in our portfolio across SASE, XDR and zero trust.
You can read our news announcement to learn more about security resilience and how we’re delivering it. But more important than the ‘how’ is the ‘why.’ Why Cisco? What makes us uniquely positioned to secure your resilience?
As I mentioned, our customers have trusted us with their networks for nearly four decades. Currently, 80 percent of the world’s internet traffic travels through Cisco infrastructure — so we have a pretty good handle on what’s going on out there. From a security standpoint alone, we have over 300,000 customers around the globe, including 100% of the Fortune 100.
As a leader in both networking and security, the breadth and depth of our solutions is unmatched. While other vendors are just beginning to join networking with security, we’ve been doing it for years. And yet, we’re continually finding ways to simplify our robust solutions for a streamlined user experience — no matter the size of your organization, where your employees work, or whether your applications are on-premises, in the cloud, or both.
Learn more about security resilience for the hybrid work era.
In addition to unparalleled infrastructure and expertise, our open, cloud-native architecture allows you to integrate with a wide range of third-party security and technology solutions for more seamless threat defense. This includes the major cloud vendors, enabling you to secure a multi-cloud environment without getting locked in with just one public cloud provider.
Additionally, all of our solutions are backed by Cisco Talos, one of the largest commercial threat intelligence teams in the world. Combined with in-depth visibility from our Cisco Secure technologies, Talos’ extensive insight into the threat landscape leads to rapid, highly effective detection and response.
Even more crucial than what we have to say is what we have heard from our customers surrounding the “new normal” for security. “I think what the security industry could use right now is a real business outcome-oriented viewpoint,” said Tom Doughty, vice president and CISO at Prudential Financial. “Meaning, what are the strategic business outcomes you’re trying to enable? Cisco can help security teams be more aligned to our business and more resilient by allowing us to see at a granular level what’s happening in our environment, especially in an extended network.”
For the law firm of George Sink, P.A., the demands of supporting hybrid work accelerated the company’s move to the cloud. The firm is now using Cisco’s new, turnkey SASE solution to securely serve its clients under any circumstance — be it a pandemic or a hurricane. According to the firm’s CIO, Timothy Mullen, “The ability to…re-establish connectivity in another region almost immediately, with my small IT team, is unheard of and a game-changing experience.”
From financial to legal transactions, and much more, we can secure it all with our open, integrated protection platform and unwavering focus on resilience. We even had the honor of securing the Super Bowl earlier this year, helping to safeguard mission-critical gameday operations.
“The Super Bowl and events of that magnitude require a humongous orchestration of interconnectedness, not only from a technology perspective but also a people standpoint,” said NFL Chief Information Security Officer, Tomás Maldonado. “What we’re trying to do is slow down the bad actors and make it more difficult for them to attack us and impact what’s happening on the field. But at the same time, we also have to look beyond the field and think about all the various parts of our business that could be affected by an attack — recognizing that our risk factors are always changing.”

We’ve all seen the headlines like “race to the cloud” and “cloud-first.” These articles and publications are true, more and more customers have adopted cloud strategies, but there is more to the story. In these customer conversations, cloud security and network security are often discussed in unison. Why is that?
Customers desire freedom and choice when establishing resilience across every aspect of their business, and this requires both the ability to remain agile, and maintain control of their organization’s most sensitive data. Neither of these can be achieved with just the cloud, or private data center. Organizations are investing in hybrid-multicloud environments to ensure continuity amidst unpredictable threats and change. But these investments will fall short if they do not include security.
The modern enterprise relies on the network more than ever before, and it looks a lot different than it did 10 years ago. According to our 2022 Global Hybrid Cloud Trends Report, where 2,500 global IT leaders were interviewed across 13 countries, 82% said they have adopted hybrid cloud architectures, and 47% of organizations use between two and three public IaaS clouds1. As organizations have grown more dependent on the network, the more complex it has become, making firewall capabilities the most critical element of the hybrid-multicloud security strategy. And Cisco has a firewall capability for every strategy, protecting your most important assets no matter where you choose to deploy it.
In May, Cisco brought offerings from Umbrella and Duo to the AWS Marketplace. Today at AWS Re:Inforce, Cisco Secure announced furthering its partnership with AWS to drive innovation with the goal to protect the integrity of your business. Validating our commitment to hybrid-multicloud security, Cisco has received the AWS Security Competency Partner designation for Network and Infrastructure Security. This designation was awarded through our demonstrated success with customer engagements and rigorous technical validations of Secure Firewall.
This week at AWS Re:Inforce, customers can stop by our booth to see our latest firewall innovation. Cisco Secure Firewall as-a-service on AWS builds on our existing portfolio, giving organizations greater flexibility and choice with a radically simplified SaaS offering. If organizations are truly to embrace security across the multi-environment IT, customers demand simplification without compromising security. With a SaaS-based form factor, management and deployment complexity is reduced. NetOps and SecOps teams will enjoy a simplified security architecture where provisioning of firewalls and control plane infrastructure are managed by Cisco. This will save your teams time by removing the need to rearchitect the network, freeing them to focus on protecting the integrity of your business.
As organizations continue to move more of their day-to-day operations to the cloud, Cisco and AWS are committed to ensure that security is an integral part of their hybrid multi-cloud strategy. We all have seen the impact of security that is bolted on, or too complex. If we are truly to find that balance between agility and protection to ensure business continuity, we need to ensure the same protections we have in the private infrastructure are easily consumed no matter where your data may roam.

Cisco and AWS demonstrate shared responsibility that identifies Security “of” the Cloud versus Security “in” the Cloud.
Shared responsibility remains central to every cloud initiative and defines how cloud providers and customers work together to achieve maximum security across all aspects of the cloud. While shared responsibility is a common term, surprisingly few people understand the model and fewer still have implemented it correctly. The lack of consistent security controls across cloud services does not go unnoticed by attackers, as they probe for vulnerabilities and slip undetected through unsecured cracks.
Security teams should start by understanding the security controls provided by their cloud service providers to help them highlight areas that are susceptible to threats and attacks. Matrices, such as the following from Amazon Web Services (AWS), give a clear view of the shared responsibility model to guide an organization’s approach:
Once Security teams understand the areas they’re responsible for securing, they can begin to construct a security model that includes the right set solutions to serve their needs.
The most effective security model is built around centralized policy and distributed enforcement, allowing security policy to be applied consistently across operating systems, applications and data using multiple security solutions. Security teams should look for ideal solutions that seamlessly integrate into their unified policy. A good first step is to ask the cloud provider for their recommendations and visit cloud marketplaces, such as the AWS Marketplace, to find and try solutions. Customers can also utilize relationships with their security vendors to obtain best practices.
As Mark Twain once said, “History doesn’t repeat itself, but it often rhymes.” There are fundamental differences between on-premise and cloud security practices and controls. However, the way in which security teams discover best practices has not changed. New playbooks from trusted vendors and cloud providers are available to help security teams implement layered approaches to securing their organizations. Security teams should examine these concepts and build on them to protect their specific cloud services without needing to reinvent new models on their own. A good place to start is Cisco’s Cloud Security page.
Watch the recent AWS and Cisco webinar to hear industry analysts, head CISO advisors, and AWS experts discuss shared responsibility, industry challenges and the ways in which other security teams are addressing the problem, and then visit the AWS Marketplace to see the latest Cisco Secure offerings. Purchasing Cisco Secure on AWS Marketplace has the additional benefit of meeting the AWS Enterprise Discount Program commitments.
What is your experience with shared responsibility? We invite you to share your thoughts.

How best to punish spammers? I give this topic a lot of thought because I spend a lot of time sifting through the endless rubbish they send me. And that's when it dawned on me: the punishment should fit the crime - robbing me of my time - which means that I, in turn, need to rob them of their time. With the smallest possible overhead on my time, of course. So, earlier this year I created Password Purgatory with the singular goal of putting spammers through the hellscape that is attempting to satisfy really nasty password complexity criteria. And I mean really nasty criteria, like much worse than you've ever seen before. I opened-sourced it, took a bunch of PRs, built out the API to present increasingly inane password complexity criteria then left it at that. Until now because finally, it's live, working and devilishly beautiful 😈
This is the easy bit - I didn't have to do anything for this step! But let me put it into context and give you a real world sample:
Ugh. Nasty stuff, off to hell for them it is, and it all begins with filing the spam into a special folder called "Send Spammer to Password Purgatory":
That's the extent of work involved on a spam-by-spam basis, but let's peel back the covers and look at what happens next.
Microsoft Power Automate (previously "Microsoft Flow") is a really neat way of triggering a series of actions based on an event, and there's a whole lot of connectors built in to make life super easy. Easy on us as the devs, that is, less easy on the spammers because here's what happens as soon as I file an email in the aforementioned folder:
Using the built in connector to my Microsoft 365 email account, the presence of a new email in that folder triggers a brand new instance of a flow. Following, I've added the "HTTP" connector which enables me to make an outbound request:
All this request does is makes a POST to an API on Password Purgatory called "create-hell". It passes an API key because I don't want just anyone making these requests as it will create data that will persist at Cloudflare. Speaking of which, let's look at what happens over there.
Let's start with some history: Back in the not too distant past, Cloudflare wasn't a host and instead would just reverse proxy requests through to origin services and do cool stuff with them along the way. This made adding HTTPS to any website easy (and free), added heaps of really neat WAF functionality and empowered us to do cool things with caching. But this was all in-transit coolness whilst the app logic, data and vast bulk of the codebase sat at that origin site. Cloudflare Workers started to change that and suddenly we had code on the edge running in hundreds of nodes around the world, nice and close to our visitors. Did that start to make Cloudflare a "host"? Hmm... but the data itself was still on the origin service (transient caching aside). Fast forward to now and there are multiple options to store data on Cloudflare's edges including their (presently beta) R2 service, Durable Objects, the (forthcoming) D1 SQL database and of most importance to this blogpost, Workers KV. Does this make them a host if you can now build entire apps within their environment? Maybe so, but let's skip the titles for now and focus on the code.
All the code I'm going to refer to here is open source and available in the public Password Purgatory Logger Github repo. Very early on in the index.js file that does all the work, you'll see a function called "createHell" which is called when the flow step above runs. That code creates a GUID then stores it in KV after which I can easily view it in the Cloudflare dashboard:
There's no value yet, just a key and it's returned via a JSON response in a property called "kvKey". To read that back in the flow, I need a "Parse JSON" step with a schema I generated from a sample:
At this point I now have a unique ID in persistent storage and it's available in the flow, which means it's time to send the spammer an email.
Because it would be rude not to respond, I'd like to send the spammer back an email and invite them to my very special registration form. To do this, I've grabbed the "Reply to email" connector and fed the kvKey through to a hyperlink:
It's an HTML email with the key hidden within the hyperlink tag so it doesn't look overtly weird. Using this connector means that when the email sends, it looks precisely like I've lovingly crafted it myself:
With the entire flow now executed, we can view the history of each step and see how the data moves between them:
Now, we play the waiting game 😊
Wasting spammer time in and of itself is good. Causing them pain by having them attempt to pass increasingly obtuse password complexity criteria is better. But the best thing - the pièce de résistance - is to log that pain and share it publicly for our collective entertainment 🤣
So, by following the link the spammer ends up here (you're welcome to follow that link and have a play with it):
The kvKey is passed via the query string and the page invites the spammer to begin the process of becoming a partner. All they need to leave is an email address... and a password. That page then embeds 2 scripts from the Password Purgatory website, both of which you can find in the open source and public Github repository I created in the original blog post. Each attempt at creating an account sends off the password only to the original Password Purgatory API I created months ago, after which it responds with the next set of criteria. But each attempt also sends off both the criteria that was presented (none on the first go, then something increasingly bizarre on each subsequent go), the password they tried to use to satisfy the criteria and the kvKey so it can all be tied together. What that means is that the Cloudflare Workers KV entry created earlier gradually builds up as follows:
There are a couple of little conditions built into the code:
That's everything needed to lure the spammer in and record their pain, now for the really fun bit 😊
The very first time the spammer's password attempt is logged, the Cloudflare Worker sends me an email to let me know I have a new spammer hooked (this capability using MailChannels only launched this year):
It was so exciting getting this email yesterday, I swear it's the same sensation as literally getting a fish on your line! That link is one I can share to put the spammer's pain on display for the world to see. This is achieved with another Cloudflare Workers route that simply pulls out the logs for the given kvKey and formats it neatly in an HTML response:
Ah, satisfaction 😊 I listed the amount of time the spammer burned with a goal to further refining the complexity criteria in the future to attempt to keep them "hooked" for longer. Is the requirement for a US post code in the password a bit too geographically specific, for example? Time will tell and I wholeheartedly welcome PRs to that effect in the original Password Purgatory API repo.
Oh - and just to ensure traction and exposure are maximised, there's a neatly formatted Twitter card that includes the last criteria and password used, you know, the ones that finally broke the spammer's spirit and caused them to give up:
Spammer burned a total of 80 seconds in Password Purgatory 😈 #PasswordPurgatory https://t.co/VwSCHNZ2AW
— Troy Hunt (@troyhunt) August 3, 2022
Clearly, I've taken a great deal of pleasure in messing with spammers and I hope you do too. I've gotta be honest - I've never been so excited to go through my junk mail! But I also thoroughly enjoyed putting this together with Power Automate and Workers KV, I think it's super cool that you can pull an app together like this with a combination of browser-based config plus code and storage that runs directly in hundreds of globally distributed edge nodes around the world. I hope the spammers appreciate just how elegant this all is 🤣
Earlier this month, the administrator of the cybercrime forum Breached received a cease-and-desist letter from a cybersecurity firm. The missive alleged that an auction on the site for data stolen from 10 million customers of Mexico’s second-largest bank was fake news and harming the bank’s reputation. The administrator responded to this empty threat by purchasing the stolen banking data and leaking it on the forum for everyone to download.
On August 3, 2022, someone using the alias “Holistic-K1ller” posted on Breached a thread selling data allegedly stolen from Grupo Financiero Banorte, Mexico’s second-biggest financial institution by total loans. Holistic-K1ller said the database included the full names, addresses, phone numbers, Mexican tax IDs (RFC), email addresses and balances on more than 10 million citizens.
There was no reason to believe Holistic-K1ller had fabricated their breach claim. This identity has been highly active on Breached and its predecessor RaidForums for more than two years, mostly selling databases from hacked Mexican entities. Last month, they sold customer information on 36 million customers of the Mexican phone company Telcel; in March, they sold 33,000 images of Mexican IDs — with the front picture and a selfie of each citizen. That same month, they also sold data on 1.4 million customers of Mexican lending platform Yotepresto.
But this history was either overlooked or ignored by Group-IB, the Singapore-based cybersecurity firm apparently hired by Banorte to help respond to the data breach.
“The Group-IB team has discovered a resource containing a fraudulent post offering to buy Grupo Financiero Banorte’s leaked databases,” reads a letter the Breach administrator said they received from Group-IB. “We ask you to remove this post containing Banorte data. Thank you for your cooperation and prompt attention to this urgent matter.”
The administrator of Breached is “Pompompurin,” the same individual who alerted this author in November 2021 to a glaring security hole in a U.S. Justice Department website that was used to spoof security alerts from the FBI. In a post to Breached on Aug. 8, Pompompurin said they bought the Banorte database from Holistic-K1ller’s sales thread because Group-IB was sending emails complaining about it.
“They also attempted to submit DMCA’s against the website,” Pompompurin wrote, referring to legal takedown requests under the Digital Millennium Copyright Act. “Make sure to tell Banorte that now they need to worry about the data being leaked instead of just being sold.”
Group-IB CEO Dmitriy Volkov said the company has seen some success in the past asking hackers to remove or take down certain information, but that making such requests is not a typical response for the security firm.
“It is not a common practice to send takedown notifications to such forums demanding that such content be removed,” Volkov said. “But these abuse letters are legally binding, which helps build a foundation for further steps taken by law enforcement agencies. Actions contrary to international rules in the regulated space of the Internet only lead to more severe crimes, which — as we know from the case of Raidforums — are successfully investigated and stopped by law enforcement.”
Banorte did not respond to requests for comment. But in a brief written statement picked up on Twitter, Banorte said there was no breach involving their infrastructure, and the data being sold is old.
“There has been no violation of our platforms and technological infrastructure,” Banorte said. “The set of information referred to is inaccurate and outdated, and does not put our users and customers at risk.”
That statement may be 100 percent true. Still, it is difficult to think of a better example of how not to do breach response. Banorte shrugging off this incident as a nothingburger is baffling: While it is almost certainly true that the bank balance information in the Banorte leak is now out of date, the rest of the information (tax IDs, phone numbers, email addresses) is harder to change.
“Is there one person from our community that think sending cease and desist letter to a hackers forum operator is a good idea?,” asked Ohad Zaidenberg, founder of CTI League, a volunteer emergency response community that emerged in 2020 to help fight COVID-19 related scams. “Who does it? Instead of helping, they pushed the organization from the hill.”
Kurt Seifried, director of IT for the CloudSecurityAlliance, was similarly perplexed by the response to the Banorte breach.
“If the data wasn’t real….did the bank think a cease and desist would result in the listing being removed?” Seifried wondered on Twitter. “I mean, isn’t selling breach data a worse crime usually than slander or libel? What was their thought process?”
A more typical response when a large bank suspects a breach is to approach the seller privately through an intermediary to ascertain if the information is valid and what it might cost to take it off the market. While it may seem odd to expect cybercriminals to make good on their claims to sell stolen data to only one party, removing sold stolen items from inventory is a fairly basic function of virtually all cybercriminal markets today (apart from perhaps sites that traffic in stolen identity data).
At a minimum, negotiating or simply engaging with a data seller can buy the victim organization additional time and clues with which to investigate the claim and ideally notify affected parties of a breach before the stolen data winds up online.
It is true that a large number of hacked databases put up for sale on the cybercrime underground are sold only after a small subset of in-the-know thieves have harvested all of the low-hanging fruit in the data — e.g., access to cryptocurrency accounts or user credentials that are recycled across multiple websites. And it’s certainly not unheard of for cybercriminals to go back on their word and re-sell or leak information that they have sold previously.
But companies in the throes of responding to a data security incident do themselves and customers no favors when they underestimate their adversaries, or try to intimidate cybercrooks with legal threats. Such responses generally accomplish nothing, except unnecessarily upping the stakes for everyone involved while displaying a dangerous naiveté about how the cybercrime underground works.
Update, Aug. 17, 10:32 a.m.: Thanks to a typo by this author, a request for comment sent to Group-IB was not delivered in advance of this story. The copy above has been updated to include a comment from Group-IB’s CEO.
Phishers are enjoying remarkable success using text messages to steal remote access credentials and one-time passcodes from employees at some of the world’s largest technology companies and customer support firms. A recent spate of SMS phishing attacks from one cybercriminal group has spawned a flurry of breach disclosures from affected companies, which are all struggling to combat the same lingering security threat: The ability of scammers to interact directly with employees through their mobile devices.
In mid-June 2022, a flood of SMS phishing messages began targeting employees at commercial staffing firms that provide customer support and outsourcing to thousands of companies. The missives asked users to click a link and log in at a phishing page that mimicked their employer’s Okta authentication page. Those who submitted credentials were then prompted to provide the one-time password needed for multi-factor authentication.
The phishers behind this scheme used newly-registered domains that often included the name of the target company, and sent text messages urging employees to click on links to these domains to view information about a pending change in their work schedule.
The phishing sites leveraged a Telegram instant message bot to forward any submitted credentials in real-time, allowing the attackers to use the phished username, password and one-time code to log in as that employee at the real employer website. But because of the way the bot was configured, it was possible for security researchers to capture the information being sent by victims to the public Telegram server.
This data trove was first reported by security researchers at Singapore-based Group-IB, which dubbed the campaign “0ktapus” for the attackers targeting organizations using identity management tools from Okta.com.
“This case is of interest because despite using low-skill methods it was able to compromise a large number of well-known organizations,” Group-IB wrote. “Furthermore, once the attackers compromised an organization they were quickly able to pivot and launch subsequent supply chain attacks, indicating that the attack was planned carefully in advance.”
It’s not clear how many of these phishing text messages were sent out, but the Telegram bot data reviewed by KrebsOnSecurity shows they generated nearly 10,000 replies over approximately two months of sporadic SMS phishing attacks targeting more than a hundred companies.
A great many responses came from those who were apparently wise to the scheme, as evidenced by the hundreds of hostile replies that included profanity or insults aimed at the phishers: The very first reply recorded in the Telegram bot data came from one such employee, who responded with the username “havefuninjail.”
Still, thousands replied with what appear to be legitimate credentials — many of them including one-time codes needed for multi-factor authentication. On July 20, the attackers turned their sights on internet infrastructure giant Cloudflare.com, and the intercepted credentials show at least three employees fell for the scam.
Image: Cloudflare.com
In a blog post earlier this month, Cloudflare said it detected the account takeovers and that no Cloudflare systems were compromised. Cloudflare said it does not rely on one-time passcodes as a second factor, so there was nothing to provide to the attackers. But Cloudflare said it wanted to call attention to the phishing attacks because they would probably work against most other companies.
“This was a sophisticated attack targeting employees and systems in such a way that we believe most organizations would be likely to be breached,” Cloudflare CEO Matthew Prince wrote. “On July 20, 2022, the Cloudflare Security team received reports of employees receiving legitimate-looking text messages pointing to what appeared to be a Cloudflare Okta login page. The messages began at 2022-07-20 22:50 UTC. Over the course of less than 1 minute, at least 76 employees received text messages on their personal and work phones. Some messages were also sent to the employees family members.”
On three separate occasions, the phishers targeted employees at Twilio.com, a San Francisco based company that provides services for making and receiving text messages and phone calls. It’s unclear how many Twilio employees received the SMS phishes, but the data suggest at least four Twilio employees responded to a spate of SMS phishing attempts on July 27, Aug. 2, and Aug. 7.
On that last date, Twilio disclosed that on Aug. 4 it became aware of unauthorized access to information related to a limited number of Twilio customer accounts through a sophisticated social engineering attack designed to steal employee credentials.
“This broad based attack against our employee base succeeded in fooling some employees into providing their credentials,” Twilio said. “The attackers then used the stolen credentials to gain access to some of our internal systems, where they were able to access certain customer data.”
That “certain customer data” included information on roughly 1,900 users of the secure messaging app Signal, which relied on Twilio to provide phone number verification services. In its disclosure on the incident, Signal said that with their access to Twilio’s internal tools the attackers were able to re-register those users’ phone numbers to another device.
On Aug. 25, food delivery service DoorDash disclosed that a “sophisticated phishing attack” on a third-party vendor allowed attackers to gain access to some of DoorDash’s internal company tools. DoorDash said intruders stole information on a “small percentage” of users that have since been notified. TechCrunch reported last week that the incident was linked to the same phishing campaign that targeted Twilio.
This phishing gang apparently had great success targeting employees of all the major mobile wireless providers, but most especially T-Mobile. Between July 10 and July 16, dozens of T-Mobile employees fell for the phishing messages and provided their remote access credentials.
“Credential theft continues to be an ongoing issue in our industry as wireless providers are constantly battling bad actors that are focused on finding new ways to pursue illegal activities like this,” T-Mobile said in a statement. “Our tools and teams worked as designed to quickly identify and respond to this large-scale smishing attack earlier this year that targeted many companies. We continue to work to prevent these types of attacks and will continue to evolve and improve our approach.”
This same group saw hundreds of responses from employees at some of the largest customer support and staffing firms, including Teleperformanceusa.com, Sitel.com and Sykes.com. Teleperformance did not respond to requests for comment. KrebsOnSecurity did hear from Christopher Knauer, global chief security officer at Sitel Group, the customer support giant that recently acquired Sykes. Knauer said the attacks leveraged newly-registered domains and asked employees to approve upcoming changes to their work schedules.
Image: Group-IB.
Knauer said the attackers set up the phishing domains just minutes in advance of spamming links to those domains in phony SMS alerts to targeted employees. He said such tactics largely sidestep automated alerts generated by companies that monitor brand names for signs of new phishing domains being registered.
“They were using the domains as soon as they became available,” Knauer said. “The alerting services don’t often let you know until 24 hours after a domain has been registered.”
On July 28 and again on Aug. 7, several employees at email delivery firm Mailchimp provided their remote access credentials to this phishing group. According to an Aug. 12 blog post, the attackers used their access to Mailchimp employee accounts to steal data from 214 customers involved in cryptocurrency and finance.
On Aug. 15, the hosting company DigitalOcean published a blog post saying it had severed ties with MailChimp after its Mailchimp account was compromised. DigitalOcean said the MailChimp incident resulted in a “very small number” of DigitalOcean customers experiencing attempted compromises of their accounts through password resets.
According to interviews with multiple companies hit by the group, the attackers are mostly interested in stealing access to cryptocurrency, and to companies that manage communications with people interested in cryptocurrency investing. In an Aug. 3 blog post from email and SMS marketing firm Klaviyo.com, the company’s CEO recounted how the phishers gained access to the company’s internal tools, and used that to download information on 38 crypto-related accounts.

The ubiquity of mobile phones became a lifeline for many companies trying to manage their remote employees throughout the Coronavirus pandemic. But these same mobile devices are fast becoming a liability for organizations that use them for phishable forms of multi-factor authentication, such as one-time codes generated by a mobile app or delivered via SMS.
Because as we can see from the success of this phishing group, this type of data extraction is now being massively automated, and employee authentication compromises can quickly lead to security and privacy risks for the employer’s partners or for anyone in their supply chain.
Unfortunately, a great many companies still rely on SMS for employee multi-factor authentication. According to a report this year from Okta, 47 percent of workforce customers deploy SMS and voice factors for multi-factor authentication. That’s down from 53 percent that did so in 2018, Okta found.
Some companies (like Knauer’s Sitel) have taken to requiring that all remote access to internal networks be managed through work-issued laptops and/or mobile devices, which are loaded with custom profiles that can’t be accessed through other devices.
Others are moving away from SMS and one-time code apps and toward requiring employees to use physical FIDO multi-factor authentication devices such as security keys, which can neutralize phishing attacks because any stolen credentials can’t be used unless the phishers also have physical access to the user’s security key or mobile device.
This came in handy for Twitter, which announced last year that it was moving all of its employees to using security keys, and/or biometric authentication via their mobile device. The phishers’ Telegram bot reported that on June 16, 2022, five employees at Twitter gave away their work credentials. In response to questions from KrebsOnSecurity, Twitter confirmed several employees were relieved of their employee usernames and passwords, but that its security key requirement prevented the phishers from abusing that information.
Twitter accelerated its plans to improve employee authentication following the July 2020 security incident, wherein several employees were phished and relieved of credentials for Twitter’s internal tools. In that intrusion, the attackers used Twitter’s tools to hijack accounts for some of the world’s most recognizable public figures, executives and celebrities — forcing those accounts to tweet out links to bitcoin scams.
“Security keys can differentiate legitimate sites from malicious ones and block phishing attempts that SMS 2FA or one-time password (OTP) verification codes would not,” Twitter said in an Oct. 2021 post about the change. “To deploy security keys internally at Twitter, we migrated from a variety of phishable 2FA methods to using security keys as our only supported 2FA method on internal systems.”
Update, 6:02 p.m. ET: Clarified that Cloudflare does not rely on TOTP (one-time multi-factor authentication codes) as a second factor for employee authentication.

It’s Partner Summit week and, for me, it’s an important reminder that no one company, not even Cisco, can do it alone. Our partners provide diverse perspectives, expertise, and solutions offerings. Each partner plays a key part in delivering the outcomes and experiences our customers need, want, and expect. So, when we say, “Let’s Own It”, it’s a rally cry for Cisco and our partners alike to do our parts to seize the massive opportunity that we have in front of us and turn it into mutual success.
Together, I know we can achieve amazing things. Foremost on my mind right now is both the opportunity and necessity to empower customers with security resilience. Resilience means customers can protect the integrity of every aspect of their business so that they can withstand unpredictable threats or changes and emerge stronger. It’s about providing controlled, trusted access to applications and services, at any time, from any place.
Resilience can also help customers deal with issues the moment they arise. If changes are needed, they will have the visibility to determine priorities, thanks to actionable intelligence and insight in the face of some major security realities that they are dealing with every day.
One, businesses are more interconnected, meaning that a breach on anyone in the value chain has dramatic ripple effects on the others.
Two, security attacks are becoming more personalized. Individuals remain one of the easiest targets for cybercriminals and their attacks are becoming more sophisticated and customized for the individual.
Three, hybrid work is here to stay. People around the world will continue to work from anywhere, on managed and unmanaged devices, over secured and unsecured networks, to applications spread across multiple clouds and data centers.
Our vision for enabling a more resilient organization is the Cisco Security Cloud. It’s an open, integrated security platform that will protect the integrity of entire IT ecosystems by safeguarding users, devices and applications across public clouds and private data centers, without public cloud lock-in. Delivering on the Security Cloud is part of our long-term product strategy; but the innovations we are announcing at Partner Summit this week are foundational elements that execute on this vision.
Specifically, we are announcing new solutions and technologies across our portfolio in Secure Connectivity, Network Security, and Zero Trust. I encourage all partners to drill down on each announcement in the accompanying blogs and news announcements. But here are the highlights of the announcements.
Helping increase resistance to phishing attacks and improve user experience through frictionless access using Duo Passwordless, which is now generally available with support for Duo Mobile as a passwordless authenticator.

Organizations embrace the public cloud for the agility, scalability, and reliability it offers when running applications. But just as organizations need these capabilities to ensure their applications operate where needed and as needed, they also require their security does the same. Organizations may introduce multiple individual firewalls into their AWS infrastructure to produce this outcome. In theory, this may be a good decision, but in practice—this could lead to asymmetric routing issues. Complex SNAT configuration can mitigate asymmetric routing issues, but this isn’t practical for sustaining public cloud operations. Organizations are looking out for their long-term cloud strategies by ruling out SNAT and are calling for a more reliable and scalable solution for connecting their applications and security for always-on protection.
To solve these challenges, Cisco created stateful firewall clustering with Secure Firewall in AWS.
Firewall clustering for Secure Firewall Threat Defense Virtual provides a highly resilient and reliable architecture for securing your AWS cloud environment. This capability lets you group multiple Secure Firewall Threat Defense Virtual appliances together as a single logical device, known as a “cluster.”
A cluster provides all the conveniences of a single device (management and integration into a network) while taking advantage of the increased throughput and redundancy you would expect from deploying multiple devices individually. Cisco uses Cluster Control Link (CCL) for forwarding asymmetric traffic across devices in the cluster. Clusters can go up to 16 members, and we use VxLAN for CCL.
In this case, clustering has the following roles:
The above diagram explains traffic flow between the client and the server with the insertion of the firewall cluster in the network. Below defines the roles of clustering and how packet flow interacts at each step.
Owner: The Owner is the node in the cluster that initially receives the connection.
Backup Owner: The node that stores TCP/UDP state information received from the Owner so that the connection can be seamlessly transferred to a new owner in case of failure.
Director: The Director is the node in the cluster that handles owner lookup requests from the Forwarder(s).
Forwarder: The Forwarder is a node in the cluster that redirects packets to the Owner.
Fragment Owner: For fragmented packets, cluster nodes that receive a fragment determine a Fragment Owner using a hash of the fragment source IP address, destination IP address, and the packet ID. All fragments are then redirected to the Fragment Owner over Cluster Control Link.
Cisco brought support for AWS Gateway Load Balancer (Figure 2). This feature enables organizations to scale their firewall presence as needed to meet demand (see details here).
Building off the previous figure, organizations can take advantage of the AWS Gateway Load Balancer with Secure Firewall’s clustering capability to evenly distribute traffic at the Secure Firewall cluster. This enables organizations to maximize the benefits of clustering capabilities including increased throughput and redundancy. Figure 3 shows how positioning a Secure Firewall cluster behind the AWS Gateway Load Balancer creates a resilient architecture. Let’s take a closer look at what is going on in the diagram.
Figure 3 shows an Internet user looking to access a workload. Before the user can access the workload, the user’s traffic is routed to Firewall Node 2 for inspection. The traffic flow for this example includes:
User -> IGW -> GWLBe -> GWLB -> Secure Firewall (2) -> GLWB -> GWLBe -> Workload
In the event of failure, the AWS Gateway Load Balancer cuts off existing connections to the failed node, making the above solution non-stateful.
Recently, AWS announced a new feature for their load balancers known as Target Failover for Existing Flows. This feature enables forwarding of existing connections to another target in the event of failure.
Cisco is an early adaptor of this feature and has combined Target Failover for Existing Flows with Secure Firewall clustering capabilities to create the industry’s first stateful cluster in AWS.
Figure 4 shows a firewall failure event and how the AWS Gateway Load Balancer uses the Target Failover for Existing Flows feature to switch the traffic flow from Firewall Node 2 to Firewall Node 3. The traffic flow for this example includes:
User -> IGW -> GWLBe -> GWLB -> Secure Firewall (3) -> GLWB -> GWLBe -> Workload
Organizations need reliable and scalable security to protect always-on applications in their AWS cloud environment. With stateful firewall clustering capabilities from Cisco, organizations can protect their applications while maintaining cloud benefits such as agility, scalability, and reliability.
Cisco Secure Firewall Threat Defense Virtual is available in the AWS marketplace, providing features like firewalling, application visibility & control, IPS, URL filtering, and malware defense. Cisco offers flexible options for firewall licensing, such as pay-as-you-go (PAYG) and bring-your-own-license (BYOL). To learn more about how Cisco Secure Firewall clustering capabilities can help protect your AWS applications, see our additional resources, check out our 30-day free trial, or speak to your Cisco sales representative.

Nowadays, “cybersecurity” is the buzzword du jour, infiltrating every organization, invited or not. Furthermore, this is the case around the world, where an increasing proportion of all services now have an online presence, prompting businesses to reconsider the security of their systems. This, however, is not news to Cisco, as we anticipated it and were prepared to serve and assist clients worldwide.
Secure Cloud Analytics, part of the Cisco Threat, Detection, and Response (TD&R) portfolio, is an industry-leading tool for tackling core Network Detection and Response (NDR) use cases. These workflows focus primarily on threat detection and how security teams may recognize the most critical issues around hunting and forensic investigations to improve their mean-time-to-respond.
Over the last year, the product team worked tirelessly to strengthen the NDR offering. New telemetry sources, more advanced detections, and observations supplement the context of essential infrastructure aspects as well as usability and interoperability improvements. Additionally, the long-awaited solution Cisco Telemetry Broker is now available, providing a richer SecOps experience across the product.
As part of our innovation story on alerting capabilities, Secure Cloud Analytics now features new detections tied to the MITRE ATT&CK framework such as Worm Propagation, Suspicious User Agent, and Azure OAuth Bypass.
Additionally, various new roles and observations were added to the Secure Cloud Analytics to improve and change user alerts, that are foundational pieces of our detections. Alerts now include a direct link to AWS’ assets and their VPC, as well as direct access to Azure Security Groups, enabling further investigation capabilities through simplified workflows. In addition, the Public Cloud Providers are now included in coverage reports that provide a gap analysis to determine which accounts are covered. Alert Details offers new device information, such as host names, subnets, and role metrics that emphasize detection techniques. To better configure alerts, we are adding telemetry to gain contextual reference on their priority. Furthermore, the ingest process has grown more robust due to data from the Talos intelligence feed and ISE.
The highly anticipated SecureX integration is now available in a single click, with no API credentials required and smooth interaction between the two platforms. Most importantly, Secure Cloud Analytics alerts may now be configured to automatically publish as incidents to the SecureX Incident Manager. The Talos Intelligence Watchlist Hits Alert is on by default due to its prominence among the many alert types.
Among other enhancements to graphs and visualizations, the Encrypted Traffic widget allows for an hourly breakdown of data. Simultaneously, the Device Report contains traffic data for a specific timestamp, which may be downloaded as a CSV. Furthermore, the Event Viewer now displays bi-directional session traffic to provide even more context to Secure Cloud Analytics flows, as well as additional columns to help with telemetry log comprehension: Cloud Account, Cloud Region, Cloud VPC, Sensor and Exporter.
On-premises sensors now provide additional telemetry on the overview page and a dedicated page where users can look further into the telemetry flowing through them in Sensor Health. To optimize the Secure Cloud Analytics deployment and improve the user experience, sensors may now be deleted from the interface.
Regarding telemetry, Cisco Telemetry Broker can now serve as a sensor in Secure Cloud Analytics, so users can identify and respond to threats faster with additional context sent to Secure Cloud Analytics. In addition, there will soon be support for other telemetry types besides IPFIX and NetFlow.
As we can see from the vast number of new additions to Secure Cloud Analytics, the product team has been working hard to understand the latest market trends, listen to the customers’ requests, and build one of the finest SaaS products in the NDR industry segment. The efforts strongly underline how Secure Cloud Analytics can solve some of the most important challenges in the NDR space around visibility, fidelity of alerts and deployment complexity by providing a cloud hosted platform that can offer insights on-premise and on cloud environments simultaneously from the same dashboard.

The use of unmanaged and IoT devices in enterprises is growing exponentially, and will account for 55.7 billion connected devices by the end of 2025. A critical concern is deploying IoT devices without requisite security controls.
While these numbers are numbing, their reality is undeniable. 90% of customers believe digitization has accelerated the importance placed upon security. The World Economic Forum now lists cybersecurity failure as a critical threat, and estimates a gap of more than 3 million security experts worldwide, hindering secure deployments at scale. Furthermore, 83% of IoT-based transactions happen over plaintext channels and not SSL, making them especially risky.
Securing an IoT device can be achieved either through securing the IoT device itself, or hardening the network it accesses. Securing devices can be cumbersome, requiring complex manufacturing partnerships and increasing unit prices, thereby reducing adoption. On the other hand, securing the network is always desirable as it helps secure access, encrypt traffic, and ease management.
Being a leader in both security and networking, Cisco continues to bring security closer to networking, providing the network with built-in security, and enabling the network to act both as sensor and as an enforcer. The convergence of security and networking leverages the network’s intelligence and visibility to enable more-informed decisions on policy and threats.
Cisco uniquely integrates security and networking, for instance we recently integrated Cisco Secure Firewall to operate on Cisco Catalyst 9000 Series switches. Additionally, Secure Firewall can be deployed in a containerized form, on-premises and in clouds. Cisco Secure Firewall classifies traffic and protects applications while stopping exploitation of vulnerable systems. Additionally, we offer Identity Services Engine with AI Endpoint Analytics to passively identify IoT devices and apply segmentation policies. Furthermore, Cisco offers management flexibility by integrating with Cisco Defense Orchestrator and DNA Center and with existing customer tools like SIEMs and XDRs.
Let’s look at three use cases where the addition of Secure Firewall capability on Catalyst 9000 Series switches solves real world problems:
Use case 1: Securing the Smart Building: This solution is ideal to secure smart buildings, converging various IoT systems into a single IT-managed network infrastructure. Smart buildings lower the operational and energy costs. Smarter building systems, however, pose serious security risks as these include so many unmanaged devices such as window shades, lighting, tailored HVAC, and more. One of the methods to secure smart buildings is to control access to avoid manipulation of sensors. Such control is attained with a networking switch with enhanced firewall capability. The firewall ensures granular segmentation, directing policies for traffic generated out of IoT devices, providing access to the right users. This integration also brings security closer to endpoints, making policy orchestration simpler.
Use Case 2: Centrally manage isolated IoT network clusters: IoT devices which communicate with each other in the same subnet typically cannot be routed, which is a challenge. By default, most IoT networks are configured in the same subnet, making it difficult to manage them centrally. Administrators are forced to physically connect to the IoT network to manage and collect telemetry. Furthermore, IoT vendors often charge hefty amounts to update IP addresses of devices. Cisco Secure Firewall, hosted on the Catalyst switch, solves this problem and not only inspects traffic from the IoT network but also translates duplicate IoT IP addresses to unique global IP addresses using NAT for centralized management of isolated IoT networks.
Use Case 3: Securely encrypt IoT traffic passing through a shared IT network: At airports, for example, multiple vendors manage unique systems such as baggage, air quality, biometric access control, etc, which share a common network. IoT traffic is usually in plain text, making it susceptible to packet sniffing, eavesdropping, man-in-the-middle attacks, and other such exploits. The IPSec capability on Cisco Secure Firewall encrypts IoT traffic, securing data transfer and reducing risk.
Cisco’s IoT initiatives join the once disconnected worlds of IT and IoT, unifying networking and security. For further details refer to the At-A Glance and see how and an Australian oil company, Ampol, fortified its retail IoT with Cisco Secure!

Cisco Live is the premier destination for Cisco customers and partners to gain knowledge and build community. Our teams work hard to deliver education and inspiration, ignite creativity, deliver practical know-how, and accelerate the connections that fuel your digital future.
The Cisco Secure team is excited to share our expertise to help power the strategies – and safety – of your organization.
In 2023, the threat landscape will evolve to one that sees attacks on every surface, from criminals who are opportunistic, yet laser-focused on their goal. The attacks themselves could be email-borne, directly targeted, socially based, or a mix of all three.
Criminals will target vulnerabilities, operational deficiencies, suppliers, and business partners, as a means of accomplishing their goals. They will use the target’s own environment and take advantage of existing people and technology problems, including alert fatigue and staffing shortages.
To face this reality and address the needs of organizations both large and small, Cisco will continue to focus on education and innovation in the areas of preventing insider threats, providing consistent and informed alerts, enabling actionable intelligence, and delivering solutions to implement a zero-trust security framework.
As the organization that pioneered networking, we are driven to secure every connection, providing end-to-end protection for users and devices across multiple clouds and networks with a seamless experience.
As our vision for the integrated Cisco Security Cloud evolves, we’re continuing to challenge existing models and unify security and networking, with foundational elements that execute on this vision. From verified push – which protects organizations from MFA-focused phishing attacks – to Wi-Fi Fingerprint, and Remembered Devices, the performance enhancements with Enterprise Single Sign-on and Cisco+ Secure Connect, we continue to meet our customers where they are, offering true zero trust, with frictionless experiences for the hybrid workforce.
We’re excited to celebrate the following innovations and updates announced at Cisco Live EMEA:
Finding the balance between usability and security is now easier than ever. With Risk-Based Authentication, users have the access they need, secured by real-time contextual signals. Organizations can increase security efficacy by dynamically adjusting authentication requirements based on risk levels and by enabling safer end-user behavior. Risk-based authentication now includes wi-fi fingerprint, remembered device, and verified push features, which work together to reduce risk while preserving user experience by only requesting additional interaction for suspicious logins or a change in risk.
Our Enterprise Ready Single Sign-on expands Duo SSO with three new capabilities to easily connect single sign-on to modern apps and empower end users. By adding major protocol support, improved admin tooling, and SSO on demand password resets, organizations enable easier and more secure access from anywhere.
Cisco SD-WAN customers can now enjoy all the benefits of a turnkey, single-vendor SASE solution that brings together industry-leading networking with security: Cisco+ Secure Connect.

I found myself going down a previously unexplored rabbit hole recently, or more specifically, what I thought was "a" rabbit hole but in actual fact was an ever-expanding series of them that led me to what I refer to in the title of this post as "6 rabbits deep". It's a tale of firewalls, APIs and sifting through layers and layers of different services to sniff out the root cause of something that seemed very benign, but actually turned out to be highly impactful. Let's go find the rabbits!
When you buy an API key on Have I Been Pwned (HIBP), Stripe handles all the payment magic. I love Stripe, it's such an awesome service that abstracts away so much pain and it's dead simple to integrate via their various APIs. It's also dead simple to configure Stripe to send notices back to your own service via webhooks. For example, when an invoice is paid or a customer is updated, Stripe sends information about that event to HIBP and then lists each call on the webhooks dashboard in their portal:
There are a whole range of different events that can be listened to and webhooks fired, here we're seeing just a couple of them that are self explanatory in name. When an invoice is paid, the callback looks something like this:
HIBP has received this call and updated it's own DB such that for a new customer, they can now retrieve an API key or for an existing customer whose subscription has renewed, the API key validity period has been extended. The same callback is also issued when someone upgrades an API key, for example when going from 10RPM (requests per minute) to 50RPM. It's super important that HIBP gets that callback so it can appropriately upgrade the customer's key and they can immediately begin making more requests. When that call doesn't happen, well, let's go down the first rabbit hole.
This should never happen:
This came in via HIBP's API key support portal and is pretty self-explanatory. I checked the customer's account on Stripe and it did indeed show an active 50RPM subscription, but when drilling down into the associated payment, I found the following:
Ok, so at least I know where things have started to go wrong, but why? Over to the webhooks dashboard and into the failed payments and things look... suboptimal:
Dammit! Fortunately this is only a small single-digit percentage of all callbacks, but every time this fails it's either stopping someone like the guy above from making the requests they've paid for or potentially, causing someone's API key to expire even though they've paid for it. The latter in particular I was really worried about as it would nuke their key and whatever they'd built on top of it would cease to function. Fortunately, because that's such an impactful action I'd built in heaps of buffer for just such an occurrence and I'd gotten onto this issue quickly, but it was disconcerting all the same.
So, what's happening? Well, the response is HTTP 403 "Forbidden" and the body is clearly a Cloudflare challenge page so something at their end is being triggered. Looks like it's time to go down the next rabbit hole.
Desperate just to quickly restore functionality, I dropped into Cloudflare's WAF and allowed all Stripe's outbound IPs used for webhooks to bypass their security controls:
This wasn't ideal, but it only created risk for requests originating from Stripe and it got things up and running again quickly. With time up my sleeve I could now delve deeper and work out precisely what was going on, starting with the logs. Cloudflare has a really extensive set of APIs that can control a heap of features of the service, including pulling back logs (note: this is a feature of their Enterprise plan). I queried out a slice of the logs corresponding to when some of the 403s from Stripe's dashboard occurred and found 2 entries similar to this one:
FreshRSS 
{"BotScore":1,"BotScoreSrc":"Verified Bot","CacheCacheStatus":"unknown","ClientASN":16509,"ClientCountry":"us","ClientIP":"54.187.205.235","ClientRequestHost":"haveibeenpwned.com","ClientRequestMethod":"POST","ClientRequestReferer":"","ClientRequestURI":"[redacted]","ClientRequestUserAgent":"Stripe/1.0 (+https://stripe.com/docs/webhooks)","EdgeRateLimitAction":"","EdgeResponseStatus":403,"EdgeStartTimestamp":1674073983931000000,"FirewallMatchesActions":["managedChallenge"],"FirewallMatchesRuleIDs":["6179ae15870a4bb7b2d480d4843b323c"],"FirewallMatchesSources":["firewallManaged"],"OriginResponseStatus":0,"WAFAction":"unknown","WorkerSubrequest":false}That's one of Stripe's outbound IP's on 54.187.205.235 and the "FirewallMatchesRuleIDs" collection has a value in it. Ergo, something about this request triggered the firewall and caused it to be challenged. I'm sure many of us have gone through the following thought process before:
What did I change?
Did I change anything?
Did they change something?
Except "they" could have been either Cloudflare or Stripe; if it wasn't me (and I was fairly certain it wasn't), was it a Cloudflare change to the rules or a Stripe change to a webhook payload that was now triggering an existing rule? Time to dig deeper again so it's over to the Cloudflare dashboard and down into the WAF events for requests to the webhook callback path:
Yep, something proper broke! Let's drill deeper and look at recent events for that IP:
As you dig deeper through troubleshooting exercises like this, you gradually turn up more and more information that helps piece the entire puzzle together. In this case, it looks like the "Inbound Anomaly Score Exceeded" rule was being triggered. What's that? And why? Time to go down another rabbit hole.
So, deeper and deeper down the rabbit holes we go, this time into the depths of the requests that triggered the managed rule:
Well that's comprehensive 🙂
There's a lot to unpack here so let's begin with the ruleset that the previously identified "Inbound Anomaly Score Exceeded" rule belongs to, the Cloudflare OWASP Core Ruleset:
The Cloudflare OWASP Core Ruleset is Cloudflare’s implementation of the OWASP ModSecurity Core Rule SetOpen external link (CRS). Cloudflare routinely monitors for updates from OWASP based on the latest version available from the official code repository.
That link is yet another rabbit hole altogether so let me summarise succinctly here: Cloudflare uses OWASP's rules to identify anomalous traffic based on a customer-defined paranoia level (how strict you want to be) and then applies a score threshold (also customer-defined) at which an action will be taken, for example challenging the request. What I learned as this saga progressed is that the "Inbound Anomoly Score Exceeded" rule is actually a rollup of the rules beneath it. The OWASP score of "26" is the sum of the 6 rules listed beneath it and once it exceeds 25, the superset rule is triggered.
Further - and this is the really important bit - Cloudflare routinely updates the rules from OWASP which makes sense because these are ever-evolving in response to new threats. And when did they last upgrade the rules? It looks like they announced it right before I started having issues:
Whilst it's not entirely clear from above when this release was scheduled to occur, I did reach out to Cloudflare support and was advised it had already taken place:
Please note that we did bump the OWASP version, which we are integrating with to 3.3.4 as noted on our scheduled changes.
So maybe it's not Cloudflare's fault or Stripe's fault, but OWASP's fault? In fairness to all, I don't think it's anyone's fault per se and is instead just an unfortunate result of everyone doing their best to keep the bad guys out. Unless... it really is Stripe's fault because there's something in the request payload that was always fishy and is now being caught? But why for only some requests and not others? Next rabbit!
Sometimes, people on the internet lose their minds a bit over things they really shouldn't. One of those things, in my experience, is Cloudflare's interception of traffic and it's something I wrote about in detail nearly 7 years ago now in my piece on security absolutism. Cloudflare plays an enormously valuable role in the internet's ecosystem and a substantial part of the value comes from being able to inspect, cache, optimise, and yes, even reject traffic. When you use Cloudflare to protect your website, they're applying rulesets like the aforementioned OWASP ones and in order to do that, they must be able to inspect your traffic! But they don't log it, not all of it, rather just "metadata generated by our products" as they refer to it on their logs page. We saw an example of that earlier on with Stripe's request from their IP showing it triggered a firewall rule, but what we didn't see is the contents of that POST request, the actual payload that triggered the rule. Let's go grab that.
Because the contents of a POST request can contain sensitive information, Cloudflare doesn't log it. Obviously they see it in transit (that's how OWASP's rules can be applied to it), but it's not stored anywhere and even if you want to capture it, they don't want to be able to see it. That's where payload logging (another Enterprise plan feature) comes in and what's really neat about that is every payload must be encrypted with a public key retained by Cloudflare whilst only you retain the private key. The setup looks like this:
Pretty self-explanatory and once done, right under where we previously saw the additional logs we now have the ability to decrypt the payload:
As promised, this requires the private key from earlier:
And now, finally, we have the actual payload that triggered the rule, seen here with my own test data:

No obvious XSS patterns, nor SQL injection or any other suspicious looking strings. The request looked totally benign, so why did it trigger the rule?
I wanted to compare the payload of a blocked request with a similar request that wasn't blocked, but they're only logged at Cloudflare when they trigger a rule. No problem, it's easy to grab the full request from Stripe's webhook history so I found one that passed and one that failed and diff'd them both:
This clearly isn't the full 200 lines, but it's a very similar story over the remainder of the files; tiny differences largely down to dates, IDs, and of course, the customers themselves. No suspicious patterns, no funky characters, nothing visibly abnormal. It's a bit pointless to even mention it because they're near identical, but the payload on the left is the one that passed the firewall whilst the payload on the right was blocked.
Next rabbit hole!
Completely running out of ideas and options, focus moved to the folks inside Cloudflare who were already aware there was an issue:
We are actively looking into this and will likely release an update to the Cloudflare OWASP ruleset soon
— Michael Tremante (@MichaelTremante) January 20, 2023
What followed was a period of back and forth initially with Cloudflare, then Stripe as well with everyone trying to nut out exactly where things were going wrong. Essentially, the process went like this:
Is Cloudflare inadvertently blocking the requests?
Is the OWASP ruleset raising false positives?
Is Stripe issuing requests that are deemed to be malicious?
And round and round we went. At one time, Cloudflare identified a change in the OWASP ruleset which appeared to have resulted in their implementation inadvertently triggering the WAF. They rolled it back and... the same thing happened. We deferred back to Stripe on the assumption that something must have changed on their end, but they couldn't identify any change that would have any sort of material impact. We were stumped, but we also had an easy fix just one last rabbit hole away...
The joy of a managed firewall is that someone else takes all the rigmarole of looking after it away. I'm going to talk more about that in the summary shortly but clearly, that also creates risk as you're delegating control of traffic flow to someone else. Fortunately, Cloudflare gives you a load of configurability with their managed rules which makes it easy to add custom exceptions:
This meant I could create a simple exception that was much more intelligent than the previous "just let all outbound Stripe IPs in" by filtering down to the specific path those webhooks were flowing in to:
And finally, because sequence matters, I dragged that rule right up to the top of the pile so it would cause matching inbound requests to skip all the other rules:
And finally, there were no more rabbits 😊
I know what you're thinking - "what was the actual root cause?" - and to be honest, I still don't know. I don't know if it was Cloudflare or OWASP or Stripe or if it even impacted other customers of these services and to be honest, yes, that's a little frustrating. But I learned a bunch of stuff and for that alone, this was a worthwhile exercise I took three big lessons away from:
Firstly, understanding the plumbing of how all these bits work together is super important. I was lucky this wasn't a time critical issue and I had the luxury of learning without being under duress; how rules, payload inspection and exception management all work together is really valuable stuff to understand. And just like that, as if to underscore my first point, I found this right before hitting the publish button on the blog post:
I added a couple more OWASP rules to the exception in Cloudflare (things like a MySQL rule that was adding 5 points), and we were back in business.
Secondly, I look at the managed WAF Cloudflare provides more favourably than I did before simply because I have a better understanding of how comprehensive it is. I want to write code and run apps on the web, that's my focus, and I want someone else to provide that additional layer on top that continuously adapts to block new and emerging threats. I want to understand it (and I now do, at least certainly better than before), but I don't want managing it day in and day out to be my job.
And finally, IMHO, Stripe needs a better mechanism to report on webhook failures:
In live mode you are notified after 3 days of trying. You can also query the events (https://t.co/0mujOPssV0) to create a running list of statuses on web hooks that have been sent and alert on that via your own app.
— Blake Krone (@blakekrone) January 19, 2023
Waiting until stuff breaks really isn't ideal and whilst I'm sure you could plug into the (very extensive) API ecosystem Stripe has, this feels like an easy feature for them to build in. So, Stripe friends, when you read this that's a big "yes" vote from me for some form of anomalous webhook response alerting.
This experience was equal parts frustration and fun and whilst the former is probably obvious, the latter is simply due to having an opportunity to learn something new that's a pretty important part of the service I run. May my frustrated fun story here make your life easier in the future if you face the same problems 😊
