A new breach involving data from nine million AT&T customers is a fresh reminder that your mobile provider likely collects and shares a great deal of information about where you go and what you do with your mobile device — unless and until you affirmatively opt out of this data collection. Here’s a primer on why you might want to do that, and how.

Telecommunications giant AT&T disclosed this month that a breach at a marketing vendor exposed certain account information for nine million customers. AT&T said the data exposed did not include sensitive information, such as credit card or Social Security numbers, or account passwords, but was limited to “Customer Proprietary Network Information” (CPNI), such as the number of lines on an account.
Certain questions may be coming to mind right now, like “What the heck is CPNI?” And, ‘If it’s so ‘customer proprietary,’ why is AT&T sharing it with marketers?” Also maybe, “What can I do about it?” Read on for answers to all three questions.
AT&T’s disclosure said the information exposed included customer first name, wireless account number, wireless phone number and email address. In addition, a small percentage of customer records also exposed the rate plan name, past due amounts, monthly payment amounts and minutes used.
CPNI refers to customer-specific “metadata” about the account and account usage, and may include:
-Called phone numbers
-Time of calls
-Length of calls
-Cost and billing of calls
-Service features
-Premium services, such as directory call assistance
According to a succinct CPNI explainer at TechTarget, CPNI is private and protected information that cannot be used for advertising or marketing directly.
“An individual’s CPNI can be shared with other telecommunications providers for network operating reasons,” wrote TechTarget’s Gavin Wright. “So, when the individual first signs up for phone service, this information is automatically shared by the phone provider to partner companies.”
Is your mobile Internet usage covered by CPNI laws? That’s less clear, as the CPNI rules were established before mobile phones and wireless Internet access were common. TechTarget’s CPNI primer explains:
“Under current U.S. law, cellphone use is only protected as CPNI when it is being used as a telephone. During this time, the company is acting as a telecommunications provider requiring CPNI rules. Internet use, websites visited, search history or apps used are not protected CPNI because the company is acting as an information services provider not subject to these laws.”
Hence, the carriers can share and sell this data because they’re not explicitly prohibited from doing so. All three major carriers say they take steps to anonymize the customer data they share, but researchers have shown it is not terribly difficult to de-anonymize supposedly anonymous web-browsing data.
“Your phone, and consequently your mobile provider, know a lot about you,” wrote Jack Morse for Mashable. “The places you go, apps you use, and the websites you visit potentially reveal all kinds of private information — e.g. religious beliefs, health conditions, travel plans, income level, and specific tastes in pornography. This should bother you.”
Happily, all of the U.S. carriers are required to offer customers ways to opt out of having data about how they use their devices shared with marketers. Here’s a look at some of the carrier-specific practices and opt-out options.
AT&T’s policy says it shares device or “ad ID”, combined with demographics including age range, gender, and ZIP code information with third parties which explicitly include advertisers, programmers, and networks, social media networks, analytics firms, ad networks and other similar companies that are involved in creating and delivering advertisements.
AT&T said the data exposed on 9 million customers was several years old, and mostly related to device upgrade eligibility. This may sound like the data went to just one of its partners who experienced a breach, but in all likelihood it also went to hundreds of AT&T’s partners.
AT&T’s CPNI opt-out page says it shares CPNI data with several of its affiliates, including WarnerMedia, DirecTV and Cricket Wireless. Until recently, AT&T also shared CPNI data with Xandr, whose privacy policy in turn explains that it shares data with hundreds of other advertising firms. Microsoft bought Xandr from AT&T last year.
According to the Electronic Privacy Information Center (EPIC), T-Mobile seems to be the only company out of the big three to extend to all customers the rights conferred by the California Consumer Privacy Act (CCPA).
EPIC says T-Mobile customer data sold to third parties uses another unique identifier called mobile advertising IDs or “MAIDs.” T-Mobile claims that MAIDs don’t directly identify consumers, but under the CCPA MAIDs are considered “personal information” that can be connected to IP addresses, mobile apps installed or used with the device, any video or content viewing information, and device activity and attributes.
T-Mobile customers can opt out by logging into their account and navigating to the profile page, then to “Privacy and Notifications.” From there, toggle off the options for “Use my data for analytics and reporting” and “Use my data to make ads more relevant to me.”
Verizon’s privacy policy says it does not sell information that personally identities customers (e.g., name, telephone number or email address), but it does allow third-party advertising companies to collect information about activity on Verizon websites and in Verizon apps, through MAIDs, pixels, web beacons and social network plugins.
According to Wired.com’s tutorial, Verizon users can opt out by logging into their Verizon account through a web browser or the My Verizon mobile app. From there, select the Account tab, then click Account Settings and Privacy Settings on the web. For the mobile app, click the gear icon in the upper right corner and then Manage Privacy Settings.
On the privacy preferences page, web users can choose “Don’t use” under the Custom Experience section. On the My Verizon app, toggle any green sliders to the left.
EPIC notes that all three major carriers say resetting the consumer’s device ID and/or clearing cookies in the browser will similarly reset any opt-out preferences (i.e., the customer will need to opt out again), and that blocking cookies by default may also block the opt-out cookie from being set.
T-Mobile says its opt out is device-specific and/or browser-specific. “In most cases, your opt-out choice will apply only to the specific device or browser on which it was made. You may need to separately opt out from your other devices and browsers.”
Both AT&T and Verizon offer opt-in programs that gather and share far more information, including device location, the phone numbers you call, and which sites you visit using your mobile and/or home Internet connection. AT&T calls this their Enhanced Relevant Advertising Program; Verizon’s is called Custom Experience Plus.
In 2021, multiple media outlets reported that some Verizon customers were being automatically enrolled in Custom Experience Plus — even after those customers had already opted out of the same program under its previous name — “Verizon Selects.”
If none of the above opt out options work for you, at a minimum you should be able to opt out of CPNI sharing by calling your carrier, or by visiting one of their stores.
Why should you opt out of sharing CPNI data? For starters, some of the nation’s largest wireless carriers don’t have a great track record in terms of protecting the sensitive information that you give them solely for the purposes of becoming a customer — let alone the information they collect about your use of their services after that point.
In January 2023, T-Mobile disclosed that someone stole data on 37 million customer accounts, including customer name, billing address, email, phone number, date of birth, T-Mobile account number and plan details. In August 2021, T-Mobile acknowledged that hackers made off with the names, dates of birth, Social Security numbers and driver’s license/ID information on more than 40 million current, former or prospective customers who applied for credit with the company.
Last summer, a cybercriminal began selling the names, email addresses, phone numbers, SSNs and dates of birth on 23 million Americans. An exhaustive analysis of the data strongly suggested it all belonged to customers of one AT&T company or another. AT&T stopped short of saying the data wasn’t theirs, but said the records did not appear to have come from its systems and may be tied to a previous data incident at another company.
However frequently the carriers may alert consumers about CPNI breaches, it’s probably nowhere near often enough. Currently, the carriers are required to report a consumer CPNI breach only in cases “when a person, without authorization or exceeding authorization, has intentionally gained access to, used or disclosed CPNI.”
But that definition of breach was crafted eons ago, back when the primary way CPNI was exposed was through “pretexting,” such when the phone company’s employees are tricked into giving away protected customer data.
In January, regulators at the U.S. Federal Communications Commission (FCC) proposed amending the definition of “breach” to include things like inadvertent disclosure — such as when companies expose CPNI data on a poorly-secured server in the cloud. The FCC is accepting public comments on the matter until March 24, 2023.
While it’s true that the leak of CPNI data does not involve sensitive information like Social Security or credit card numbers, one thing AT&T’s breach notice doesn’t mention is that CPNI data — such as balances and payments made — can be abused by fraudsters to make scam emails and text messages more believable when they’re trying to impersonate AT&T and phish AT&T customers.
The other problem with letting companies share or sell your CPNI data is that the wireless carriers can change their privacy policies at any time, and you are assumed to be okay with those changes as long as you keep using their services.
For example, location data from your wireless device is most definitely CPNI, and yet until very recently all of the major carriers sold their customers’ real-time location data to third party data brokers without customer consent.
What was their punishment? In 2020, the FCC proposed fines totaling $208 million against all of the major carriers for selling their customers’ real-time location data. If that sounds like a lot of money, consider that all of the major wireless providers reported tens of billions of dollars in revenue last year (e.g., Verizon’s consumer revenue alone was more than $100 billion last year).
If the United States had federal privacy laws that were at all consumer-friendly and relevant to today’s digital economy, this kind of data collection and sharing would always be opt-in by default. In such a world, the enormously profitable wireless industry would likely be forced to offer clear financial incentives to customers who choose to share this information.
But until that day arrives, understand that the carriers can change their data collection and sharing policies when it suits them. And regardless of whether you actually read any notices about changes to their privacy policies, you will have agreed to those changes as long as you continue using their service.

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!

For Cisco engineers working on Duo, having a remote-first workplace has helped them reach life goals, connect with colleagues around the world, and be intentional communicators. We understand that working remotely can be an adjustment — that’s why we’ve compiled the 10 parts of remote work that surprised our team members most and their advice for navigating the nuances. If you’re interested in being part of a remote-first workplace, check out our open positions.
Senior Engineering Leader David Rines has worked remotely for the past seven years. He’s found that Cisco’s approach to distributed teams has “enabled us to pick up the right talent, and not necessarily local talent. We are moving towards a global, follow the sun environment,” he said.
One of the aspects Rines appreciates most of this structure is getting “a widely varied set of perspectives and experiences that help build a more reliable, more robust product, which is why we’re here.”
Another benefit to having colleagues across the globe is the sharing of recipes, a perk Senior Site Reliability Engineer Bernard Ting particularly enjoys. Proactively communicating with colleagues virtually “helps you to form bonds with people from other teams. You can always learn something new about cultures elsewhere. I talk to people about food and so I’m always gathering recipes from people from all over the world,” Ting shared.
While some may fear that working remotely could lead to feelings of isolation and loneliness, a different camaraderie can flourish in the structure of our distributed teams. With colleagues across time zones, “there’s always someone there who you can reach out to help solve your problem,” Rines said.
Collaboration hours are another way Site Reliability Engineering Manager Jaya Sistla has cultivated virtual community and problem-solving. These hours are blocked off for team members to talk about what they’re working on. “The main thing is being able to ask for help so you don’t go into the rabbit hole debugging things,” Sistla said.
Ting points out that working in a distributed model allows you to really engage in virtual events and conversations. Given that the team mainly communicates through online chat, Ting has found that “forces you to see everyone as equally approachable, which has made me more comfortable reaching out to people from anywhere in the world.”
For folks sharing an office, collaboration can happen through casual chats over coffee. When facing a challenge, you can ask your neighbor for support. While ideally virtual communication could have a similar cadence and spontaneity, the logistics of remote and distributed work require intentionality and being proactive in connecting with colleagues as people and as co-workers.
When Ting first started working remotely, he felt that every meeting needed to be formal and have a business objective. By sharing his feelings with his manager, he was reassured that “socializing is a very important part of teamwork, because if you don’t have a good relationship with your colleagues you’re not going to be able to have healthy discussions, healthy conflict or be able to critique each other when the situation arises.”
Since that conversation, Ting has been more proactive about catching up with colleagues, which can include sharing a coffee over video chat. Duo’s “coffee roulette” formalizes the process as every month, employees who opt in can be randomly paired up for a quick half-hour chat focused exclusively on socializing. Ting has found being proactive about socializing virtually helpful. “It’s made me more intentional with my time and really treasure the social experience you can get,” he said.
Some folks may be concerned that without a manager observing their efforts and work ethic day in and day out, it may be harder to recognize accomplishments and challenges. Ting found that within his team “when you work on projects and in your one-on-ones with your managers, they’re always very intentional about learning what you’ve been doing and seeing what your progress is like on certain projects. I’ve been asked, ‘How do you think you can improve? What are some of the things you’ve been doing outside of the team work?’”
To cultivate cross-team collaboration and education, there are thoughtfully planned virtual lunch and learns. “We schedule training sessions and common meetings at times that are flexible for everyone. If it has to be repeated, we do it so people can comfortably attend rather than stretching themselves and attending at odd hours,” Sistla said.
For Software Engineer Nick Aspinall, an important and fun part of working remotely is keeping in touch with virtual messaging. One unique perk has been getting to create and customize emojis with team members including a few of himself in “various ridiculous states,” he said.
Connecting with colleagues on themed channels focused on personal and professional interests from coffee to pets “makes it really cool because you can meet people across different teams and still get some of the feeling of rubbing elbows that you get when you’re in the office,” Aspinall said. Participating in these virtual conversations boosts morale while also providing an endless supply of cute animal pics.
Given the multi-faceted nature of our work and the importance of consistent information sharing, having different communication channels and formats to communicate data with varying degrees of complexity is vital. Having information readily accessible, accurate and updated is particularly necessary in a field like cybersecurity.
Senior Software Engineer Mario Lopez finds that the variety of information sources contributes to an easeful remote working experience. For instance, for complex architecture decisions or detailing, Duo’s Wiki is the best source.
Software Engineer Hanna Fernandez has benefited from chat channels dedicated to design and engineering topics to “see what everyone’s up to and what thoughts people have,” she said. Sista pointed out these are great places to ask questions and open up dialogue to solve problems.
Our culture is “video-on,” meaning that it is preferred that during video meetings, as much as possible, attendees have their cameras on. Lopez loves this because “you get a bit of that personal human element.”
“We’re all people behind these screens. You definitely get some of people’s personality through text, but you get it more when you actually see them. It’s infectious when you see someone smiling. You’ve got to smile back,” he shared (while we both smiled).
When Fernandez started at Cisco, she was advised to schedule individual meetings with everyone she would be working with on every team that she joined. That suggestion is one she’s applied even virtually.
“It’s a great strategy because I already know that my team is super talented and very smart, but this way I also get to know them as humans beyond their roles,” Fernandez said. Fernandez also finds it important to check in with co-workers and ask how they’re feeling and how their time off was. “I know a lot of people hate small talk, but it’s not just small talk. I’m genuinely interested in how my co-workers are doing.”
One of Ting’s biggest goals was buying his first house in the countryside outside of London. By working remotely, Ting has flexibility in his location which allowed him to achieve his goal of buying a house and settling down with his partner, while giving their dogs the space they need to be dogs.
When transitioning from fully remote to hybrid, it’s important to recognize that there will be some shifts to get accustomed to. As the structures of remote, distributed and hybrid work evolve, it’s important to stay flexible and notice what’s possible through multiple modalities of team building. Many teams have enjoyed in-person gatherings and connecting through virtual lunches and team games when remote.
Fernandez has had multiple roles with multiple structures at Cisco. As an intern, she was fully in person and shared desk space with other interns who collaborated on full stack engineering. While working in finance IT, Fernandez was hybrid and many of her colleagues were distributed among multiple offices. The pandemic began while she was in a DevOps role, forcing her to maintain boundaries around her work time while working fully remotely. In her current role working on Duo, Fernandez is completely remote but advocates for in-person events if possible, because “humans are social creatures who want to see each other’s faces in real life once in a while.”
For Aspinall, “when we did come back to the office, there was a bit of an adjustment period where you were overstimulated from the office.” He also wanted to ensure team members who were 100% remote were fully included. Now he sees that while half his team is fully remote and the other half is hybrid, “that doesn’t stop anyone from doing anything. All of our meetings feel the same. They’re all seamless.”

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. Learn more about new features that allow Secure Cloud Analytics to detect, analyze, and respond to the most critical dangers to their company much more quickly.

Cybersecurity has changed dramatically since the dawn of firewalls in the 1980s. But despite all the upheaval and innovation, they have stood the test of time. The basic concept of allowing “good” traffic to flow and blocking the bad stuff remains essential. Of course, it looks much different now than in the era of Care Bears and Cabbage Patch Kids.
Today’s workers, data, and applications are everywhere, and firewalls must be as well. There’s no longer just one finite space to defend. With the recent explosion of hybrid work and the rapid transition to multi-cloud environments, it’s imperative that firewalls evolve alongside a business — and be ready for whatever’s next.
So, can your firewall grow with you? Or is it stuck in the age of Hair Bands and He-Man?
The past few years have brought about a keen focus on resilience — remaining strong, yet adaptable in the face of unexpected and even unfathomable challenges. But an organization cannot persevere without security being at the forefront of any resilience strategy.
96% of executives consider security resilience highly important to their business.

Firewalls are a critical foundation for building powerful, resilient security infrastructure. Yet contemporary firewalls have to be and do more than one thing. Cisco Secure Firewall delivers world-class security controls wherever you need them, with unified visibility and consistent policy management and enforcement.
As a worldwide leader in networking and security, Cisco is better positioned than any other vendor to incorporate effective firewall controls into your infrastructure — anywhere your data and applications reside. According to a study conducted on behalf of Cisco by Forrester Research, Cisco Secure Firewall customers can:
Cisco Secure Firewall delivers on several key aspects necessary for security resilience: visibility, flexibility, intelligence, integration, and unified controls. Together, they enable organizations to close gaps, see and detect threats faster, and adapt quickly to change.
Watch video: Cisco Secure Firewall Overview
With most of today’s internet traffic being encrypted, security measures can become obsolete without the ability to see into all traffic, encrypted or not. While decryption is commonplace, it is simply not feasible in many cases, and can have serious impacts on network performance. With its Encrypted Visibility Engine, Cisco Secure Firewall leverages deep packet inspection (DPI) to identify potentially malicious applications in encrypted traffic without offloading to another appliance and degrading performance.
Due to a highly distributed network and workforce, as well as constantly maturing attacks, the ability to see into every corner of your ecosystem is crucial. Cisco Secure Firewall blends multiple technologies to detect and block more threats in more places. By combining traditional firewall capabilities with URL filtering, application visibility and control, malware defense, and Snort 3 intrusion prevention, organizations gain robust protection against even the most sophisticated threats.
Cisco offers a wide variety of firewalls for defending the different areas of your network — including physical, virtual, and cloud-native — as well as cloud-delivered. We can secure businesses and offices of all types and sizes, from the data center to the cloud.
Cisco Secure also provides flexible firewall management options, enabling you to deploy and operate your security architecture in a way that is tailored to the unique requirements of your NetOps, SecOps, and DevOps teams. No matter which firewall models you choose or environments you operate in (physical or virtual), you can use a single, simplified application to manage all your firewalls from one place.
The threat landscape changes every day, and our defenses must change with it. Cisco Talos is one of the largest and most trusted threat intelligence groups in the world. Its in-depth insight into global threats, and advanced research and analysis, enable us to quickly incorporate protections for new threats into our products via hourly updates. That way, Cisco customers are continuously safeguarded from both known and unknown threats.
“When the Log4j vulnerability was discovered, we were protected before we even completed our patching,” said Paul Smith, network administrator at Marian University. “As a result of automated hourly updates from Talos, Cisco Secure Firewall had an early detection signature, so it was already blocking the concerning traffic from infiltrating our network.”
Another differentiator for Cisco Secure Firewall is that it’s part of an integrated security ecosystem. With Cisco SecureX, organizations can correlate data from multiple technologies and unleash XDR capabilities for a centralized, automated response to threats.
“At the end of the day, it’s about protecting the data, and we do that with the integration of [Cisco] Secure Endpoint, Umbrella, and Secure Firewall, which combine to protect the networks, endpoints, workstations, and servers — and all of this can be correlated easily within SecureX.”
– Elliott Bujan, IT Security Manager, Marine Credit Union
The new Cloud-delivered Firewall Management Center leverages the cloud to facilitate agile, simplified operations for a distributed, hybrid network. It provides efficiency at scale by allowing security teams to swiftly deploy and update policies across their environment with just a few clicks, as well as take coordinated actions to prioritize, investigate, and remediate threats within a single pane of glass. And with a cloud-delivered management center, Cisco regularly updates its software behind the scenes, which reduces risk, maintains compliance, and gives your team more time to focus on other priorities.
Additionally, Cisco Secure Firewall dynamically shares policies driven by intelligence from Cisco Secure Workload, which uses microsegmentation to prevent lateral movement of attackers throughout a network. This allows security policies to be harmonized across both the network and application environments, boosting efficacy and fostering collaboration between teams.
These are just some examples of what makes up a comprehensive, modernized firewall. But Cisco is not stopping there. We continue to innovate to meet evolving business needs. For example, the new enterprise-class 3100 Series firewalls are specially designed for hybrid work, supporting more end users with high-performance remote access for increased organizational flexibility.
Additionally, Cisco Secure Firewall serves as a key component of advanced security strategies including XDR, SASE, and zero trust, helping businesses keep pace with accelerating digital transformation. According to Cisco’s most recent Security Outcomes Report, organizations with mature XDR, SASE, and zero trust implementations all boast significantly higher levels of security resilience.
Fuel and energy retailer, Ampol, uses a variety of Cisco technologies, including Secure Firewall, to segment and safeguard its network. “Cisco was an integral part of our success during COVID-19 as we were able to serve customers without interruption in stores,” said Amir Yassa, senior project specialist at Ampol. “Deploying our retail resilience project, mostly comprised of Cisco products, enabled us to reduce our IT-related incidents by 90%, thus enabling us to serve our customers better now and into the future.”

Have you ever been browsing online and clicked a link or search result that took you to a site that triggers a “your connection is not private” or “your connection is not secure” error code? If you’re not too interested in that particular result, you may simply move on to another result option. But if you’re tempted to visit the site anyway, you should be sure you understand what the warning means, what the risks are, and how to bypass the error if you need to.
A “your connection is not private” error means that your browser cannot determine with certainty that a website has safe encryption protocols in place to protect your device and data. You can bump into this error on any device connected to the internet — computer, smartphone, or tablet.
So, what exactly is going on when you see the “this connection is not private” error?
For starters, it’s important to know that seeing the error is just a warning, and it does not mean any of your private information is compromised. A “your connection is not private” error means the website you were trying to visit does not have an up-to-date SSL (secure sockets layer) security certificate.
Website owners must maintain the licensing regularly to ensure the site encryption capabilities are up to date. If the website’s SSL certificate is outdated, it means the site owners have not kept their encryption licensing current, but it doesn’t necessarily mean they are up to no good. Even major websites like LinkedIn have had momentary lapses that would throw the error. LinkedIn mistakenly let their subdomain SSL certificates lapse.
In late 2021, a significant provider of SSL certificates, Let’s Encrypt, went out of business. When their root domain officially lapsed, it created issues for many domain names and SSL certificates owned by legitimate companies. The privacy error created problems for unwitting businesses, as many of their website visitors were rightfully concerned about site security.
While it does not always mean a website is unsafe to browse, it should not be ignored. A secure internet connection is critical to protecting yourself online. Many nefarious websites are dangerous to visit, and this SSL certificate error will protect you from walking into them unaware.
SSL certification standards have helped make the web a safer place to transact. It helps ensure online activities like paying bills online, ordering products, connecting to online banking, or keeping your private email accounts safe and secure. Online security continues to improve with a new Transport Layer Security (TLS) standard, which promises to be the successor protocol to SSL.
So be careful whenever visiting sites that trigger the “connection is not private” error, as those sites can potentially make your personal data less secure and make your devices vulnerable to viruses and malware.
Note: The “your connection is not private” error is Google Chrome‘s phrasing. Microsoft Edge or Mozilla Firefox users will instead see a “your connection is not secure” error as the warning message.
If you feel confident that a website or page is safe, despite the warning from your web browser, there are a few things you can do to troubleshoot the error.
Remember, you are taking your chances anytime you ignore an error. As we mentioned, you could leave yourself vulnerable to hackers after your passwords, personal information, and other risks.
Your data and private information are valuable to hackers, so they will continue to find new ways to try and procure it. Here are some ways to protect yourself and your data when browsing online.
As we continue to do more critical business online, we must also do our best to address the risks of the internet’s many conveniences.
A comprehensive cybersecurity tool like McAfee+ Ultimate can help protect you from online scams, identity theft, and phishing attempts, and ensure you always have a secure connection. McAfee helps keep your sensitive information out of the hands of hackers and can help you keep your digital data footprints lighter with personal data cleanup.
With McAfee’s experts on your side, you can enjoy everything the web offers with the confidence of total protection.

Cyber security implies protecting the confidentiality, availability and integrity of computer systems and networks. Often security researchers and security teams focus on threats to software and the risks associated with authenticating and managing users. However, computing systems are built upon a tall stack of computing resources.
Each layer within the stack is exposed to specific threats which need to be considered as part of a cyber security strategy. As the threat landscape evolves and exposure to risk changes, organizations need to review their threat exposure and consider if current mitigations are sufficient for their needs.
The recent disruption of the Nord Stream submarine gas pipeline in the Baltic Sea by an apparent act of sabotage highlights the risks to infrastructure located beneath the waves. The telecommunications infrastructure that carries internet traffic between countries and continents is often provided by submarine cables. These cables are relatively few in number but carry vast amounts of internet and enterprise traffic, potentially from many different service providers.
The seabed is a challenging environment for infrastructure. Sea water is corrosive, the pressure on the ocean floor can be extreme, while earthquakes, ship’s anchors and dredging provide additional risks to may result in the severing of a cable. Submarine cables are only expected to achieve a lifespan in the region of 25 years before failure.
Repairing or replacing a submarine cable is expensive and time consuming. It may be many months before a failed cable can be repaired or replaced. In the absence of a functioning cable, internet connections must be rerouted to avoid disruption. However, this risks saturating the remaining infrastructure and adversely affecting the quality of connections.
Organizations that require high availability international or intercontinental network connections should review their exposure to the risk of submarine cables failure. The nature of this risk will depend on how services are currently delivered.
At the time of writing there is no specific threat to undersea infrastructure. Other than attacks against terrestrial cables, no cable damage has been shown to be due to sabotage. Nevertheless, the Secretary General of NATO has stressed the importance of undersea cables to civilian society and military capability [1]. The British Chief of Defense Staff has warned how seriously intentional damage to telecommunications cables would be taken [2].
Physical infrastructure can not be taken for granted. Organizations would do well to review the impact of one or more submarine cables being taken out of service. Preparing response plans and contingencies in advance ensures that disruption is kept to a minimum in the event that such a scenario occurs.

Since 1996, United Nations members have commemorated Nov. 16 as International Day of Tolerance. As a word, tolerance can mean different things to different people and cultures. The UN defines tolerance as: “respect, acceptance and appreciation of the rich diversity of our world’s cultures, our forms of expression and ways of being human.” I define it slightly differently. To me, tolerance is acceptance. Tolerance is inclusion. Tolerance is humanity. Tolerance is letting people be and live authentically as they choose.
Being able to live authentically is key. It’s about creating an environment for everyone to fit in and feel a sense of belonging. In a way, this means obfuscating the “standard” and stop paying attention to the degrees of variation from it. Tolerance is a step one in that process and a critical step toward a more diverse and tolerant world.
But if this is the goal, I say we have lots of work left in promoting this within our workforce, especially in the cybersecurity industry. I wrote extensively about this in a blog last year on why diversity matters so much to create stronger cybersecurity organizations. I pointed out that cybersecurity as a technology is multi-faceted and constantly changing. So, it would make sense that a highly diverse organization would provide different perspectives and more creative solutions to these challenges.
Even in the face of this logical goal of creating more diverse workforces, legacy recruiting, education, and even hiring practices are holding us back as an industry. I’ll look at one workforce populations specifically, women in cybersecurity. Currently, women constitute less than 25 percent of the workforce in cybersecurity. Of course, this is inclusive of all roles in cybersecurity meaning that I think it’s fair to say that the percentage of women in technical cybersecurity roles (e.g., software and hardware engineering) would be much lower. That’s discouraging, especially when there are still more than 700,000 cybersecurity positions that remain unfilled, many of them being high-paying roles.
Perhaps the more important question is “why?” The International Information System Security Certification Consortium (ISC2) commissioned a study to examine this issue closely and came up with some important conclusions that I’ll summarize.
In promoting the International Day of Tolerance, Secretary-General Ban Ki-moon listed three ways we as a global society can be more tolerant: education, inclusion, and opportunities. As it happens, those are also exactly the approaches required to create more diverse workforces.
Of the three, I believe education (the earlier the better) is key as it’s foundational to being able to take advantage of inclusion and opportunities. Yes, we must continue to invest in STEM education and encourage more girls and minorities to take part. But the harder challenge is to somehow overcome the perception issue among large parts of these populations that the STEM field is not for them.
I believe that will require an investment in time and interaction in the form of mentoring and community outreach. For example, the Cisco Women in Technology employee resource organization that I’m proud to be the executive sponsor for, started a coding bootcamp targeting underrepresented populations. There will be many more bootcamps next year including weeklong camps in the summer. We need more of this, much more and I know there are many companies in cybersecurity who have similar aspirations and programs.
So, on this International Day of Tolerance, I ask my fellow cybersecurity professionals to at least think of ways they can influence someone in an underrepresented population to explore a career in the STEM field including cybersecurity. Take part in local volunteer activities at a school, especially in an inner-city one, like the kind that the Cisco Networking Academy is renowned for. Join and be an active participant in one of many cybersecurity organizations and affinity groups. Become a sponsor and a mentor to a girl or a minority and help encourage them to get ready to join this exciting and lucrative industry.
But whatever you do, get started. Author and activist Rachel Cargle spoke to us earlier this year as part of our Black History Month celebration about what it means to show up with purpose toward addressing many injustices that still exist today. “There’s an incredible disconnect here between humanity and dignity and all of this stuff in the country, and that should hopefully push you to action,” she said. Indeed, as these are issues that have existed for decades, and we will not solve them in a day, a month, or even a year. But if we don’t start, I’m afraid that the diversity issues that I’ve highlighted will be much the same in the International Day of Tolerance for years to come.

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).

The word is out! Cisco Secure Endpoint’s effectiveness is off the charts in protecting your enterprise environment.
This is not just a baseless opinion; however, the facts are rooted in actual test results from the annual AV-Comparative EPR Test Report published in October 2022. Not only did Secure Endpoint knock it out of the park in enterprise protection; but Cisco Secure Endpoint obtained the lowest total cost of ownership (TCO) per agent at $587 over 5 years. No one else was remotely close in this area. More to come on that later.
If you are not familiar with the “AV-Comparatives Endpoint Prevention and Response Test is the most comprehensive test of EPR products ever performed. The 10 products in the test were subjected to 50 separate targeted attack scenarios, which used a variety of different techniques.”
These results are from an industry-respected third-party organization that assesses antivirus software and has just confirmed what we know and believe here at Cisco, which is our Secure Endpoint product is the industry’s best of the best.
Look for yourself at where we landed. That’s right, Cisco Secure Endpoint smashed this test, we are almost off the quadrant as one of the “Strategic Leaders”.
We ended up here for a combination of reasons, with the top being our efficacy in protecting our customers’ environments in this real-world test that emulates multi-stage attacks similar to MITRE’s ATT&CK evaluations which are conducted as part of this process (click here for an overview of MITRE ATT&CK techniques). Out of all the 50 scenarios tested, Secure Endpoint was the only product that STOPPED 100% of targeted threats toward enterprise users, which prevented further infiltration into the organization.
In addition, this test not only assesses the efficacy of endpoint security products but also analyzes their cost-effectiveness. Following up on my earlier remarks about achieving the lowest cost of ownership, the graph below displays how we stacked up against other industry players in this space including several well-known vendors that chose not to display their names due to poor results.
These results provide a meaningful proof point that Cisco Secure Endpoint is perfectly positioned to secure the enterprise as well as secure the future of hybrid workers.
Enriched with built-in Extended Detection and Response (XDR) capabilities, Cisco Secure Endpoint has allowed our customers to maintain resiliency when faced with outside threats.
As we embark on securing “what’s next” by staying ahead of unforeseen cyber threats of tomorrow, Cisco Secure Endpoint integration with the complete Cisco Secure Solutions portfolio allows you to move forward with the peace of mind that if it’s connected, we can and will protect it.
