Unscrambling Cybersecurity Acronyms – The ABCs of MDR and XDR Security

By Nirav Shah

In the second part of this blog series on Unscrambling Cybersecurity Acronyms, we covered Endpoint Detection and Response (EDR) and Managed Endpoint Detection and Response (MEDR) solutions, which included an overview of the evolution of endpoint security solutions. In this blog, we’ll go over Managed Detection and Response (MDR) and Extended Detection and Response (XDR) solutions in more depth.

What are Managed Detection and Response (MDR) solutions? 

MDR solutions are a security technology stack delivered as a managed service to customers by third-parties such as cybersecurity vendors or Managed Service Providers (MSPs). They’re similar to Managed Endpoint Detection and Response (MEDR) solutions since both solutions are managed cybersecurity services that use Security Operations Center (SOC) experts to monitor, detect, and respond to threats targeting your organization. However, the main difference between these two offerings is that MEDR solutions monitor only your endpoints while MDR solutions monitor a broader environment.

While MDR security solutions don’t have an exact definition for the types of infrastructure they monitor and the underlying security stack that powers them, they often monitor your endpoint, network, and cloud environments via a ‘follow the sun’ approach that uses multiple security teams distributed around the world to continually defend your environment. These security analysts monitor your environment 24/7 for threats, analyze and prioritize threats, investigate potential incidents, and offer guided remediation of attacks. This enables you to quickly detect advanced threats, effectively contain attacks, and rapidly respond to incidents.

More importantly, MDR security solutions allow you to augment or outsource your security to cybersecurity experts. While nearly every organization must defend their environment from cyberattacks, not every organization has the time, expertise, or personnel to run their own security solution. These organizations can benefit from outsourcing their security to MDR services, which enable them to focus on their core business while getting the security expertise they need. In addition, some organizations don’t have the budget or resources to monitor their environment 24/7 or they may have a small security team that struggles to investigate every threat. MDR security services can also help these organizations by giving them always-on security operations while enabling them to address every threat to their organization.

One drawback to deploying an MDR security service is that you become dependent on a third-party for your security needs. While many organizations don’t have any issues with this, some organizations may be hesitant to hand over control of their cybersecurity to a third-party vendor. In addition, organizations such as larger, more-risk averse companies may not desire an MDR service because they’ve already made cybersecurity investments such as developing their own SOC. Finally, MDR security solutions don’t have truly unified detection and response capabilities since they’re typically powered by heterogenous security technology stacks that lack consolidated telemetry, correlated detections, and holistic incident response. This is where XDR solutions shine.

What are Extended Detection and Response (XDR) solutions? 

XDR solutions unify threat monitoring, detection, and response across your entire environment by centralizing visibility, delivering contextual insights, and coordinating response. While ‘XDR’ means different things to different people because it’s a fairly nascent technology, XDR solutions usually consolidate security telemetry from multiple security products into a single solution. Moreover, XDR security solutions provide enriched context by correlating alerts from different security solutions. Finally, comprehensive XDR solutions can simplify incident response by allowing you to automate and orchestrate threat response across your environment.

These solutions speed up threat detection and response by providing a single pane of glass for gaining visibility into threats as well as detecting and responding to attacks. Furthermore, XDR security solutions reduce alert fatigue and false positives with actionable, contextual insights from higher-fidelity detections that mean you spend less time sifting through endless alerts and can focus on the most critical threats. Finally, XDR solutions enable you to streamline your security operations with improved efficiency from automated, orchestrated response across your entire security stack from one unified console.

A major downside to XDR security solutions is that you typically have to deploy and manage these solutions yourself versus having a third-party vendor run them for you. While Managed XDR (MXDR) services are growing, these solutions are still very much in their infancy. In addition, not every organization will want or need a full-fledged XDR solution. For instance, organizations with a higher risk threshold may be satisfied with using an EDR solution and/or an MDR service to defend their organization from threats.

Choosing the Right Cybersecurity Solution  

As I mentioned in the first and second parts of this blog series, you shouldn’t take a ‘one-size-fits-all’ approach to cybersecurity since every organization has different needs, goals, risk appetites, staffing levels, and more. This logic holds true for MDR and XDR solutions, with these solutions working well for certain organizations and not so well for other organizations. Regardless, there are a few aspects to consider when evaluating MDR and XDR security solutions.

One factor to keep in mind is if you already have or are planning on building out your own SOC. This is important to think about because developing and operating a SOC can require large investments in cybersecurity, which includes having the right expertise on your security teams. Organizations unwilling to make these commitments usually end up choosing managed security services such as MDR solutions, which allows them to protect their organization without considerable upfront investments.

Other critical factors to consider are your existing security maturity and overall goals. For instance, organizations who have already made significant commitments to cybersecurity often think about ways to improve the operational efficiency of their security teams. These organizations frequently turn to XDR tools since these solutions reduce threat detection and response times, provide better visibility and context while decreasing alert fatigue. Moreover, organizations with substantial security investments should consider open and extensible XDR solutions that integrate with their existing tools to avoid having to ‘rip and replace’ security tools, which can be costly and cumbersome.

I hope this blog series on the different threat detection and response solutions help you make sense of the different cybersecurity acronyms while guiding you in your decision on the right security solution for your organization.

Unscrambling Cybersecurity Acronyms: The ABCs of EDR and MEDR Security

By Nirav Shah

In the first part of this blog series on Unscrambling Cybersecurity Acronyms, we provided a high-level overview of the different threat detection and response solutions and went over how to find the right solution for your organization. In this blog, we’ll do a deeper dive on two of these solutions – Endpoint Detection and Response (EDR) and Managed Endpoint Detection and Response (MEDR). However, first let’s take a look back at the history of endpoint security solutions and understand how we got EDR and MEDR security solutions.

Evolution of endpoint security solutions

The very first endpoint security solutions started out as anti-virus solutions (AV) with basic security functionality that relied heavily on signature-based detection. These solutions were effective against known threats where a signature was created, but ineffective against unknown threats such as new and emerging attacks. That meant that organizations struggled to stay ahead of attackers, who were continuously evolving their techniques to evade detection with new types of malware.

To address this problem, AV vendors added detection technologies such as heuristics, reputational analysis, behavioral protection, and even machine learning to their solutions, which became known as Endpoint Protection Platforms (EPP). These unified solutions were effective against both known and unknown threats and frequently used multiple approaches to prevent malware and other attacks from infecting endpoints.

As cyberattacks grew increasingly sophisticated though, many in the cybersecurity industry recognized that protection against threats wasn’t enough. Effective endpoint security had to include detection and response capabilities to quickly investigate and remediate the inevitable security breach. This led to the creation of EDR security solutions, which focused on post-breach efforts to contain and clean up attacks on compromised endpoints.

Today, most endpoint security vendors combine EPP and EDR solutions into a single, converged solution that provides holistic defense to customers with protection, detection, and response capabilities. Many vendors are also offering EDR as a managed service (also known as MEDR) to customers who need help in securing their endpoints or who don’t have the resources to configure and manage their own EDR solution. Now that we’ve gone over how endpoint security evolved into EDR and MEDR security solutions, let’s cover EDR and MEDR in more depth.

Figure 1: History of Endpoint Security Solutions

What are Endpoint Detection and Response (EDR) solutions?

EDR solutions continuously monitor your endpoints for threats, alert you in case suspicious activity is detected, and allow you to investigate, respond to and contain potential attacks. Moreover, many EDR security solutions provide threat hunting functionality to help you proactively spot threats in your environment. They’re often coupled with or part of a broader endpoint security solution that also includes prevention capabilities via an EPP solution to protect against the initial incursion.

As a result, EDR security solutions enable you to protect your organization from sophisticated attacks by rapidly detecting, containing, and remediating threats on your endpoints before they gain a foothold in your environment. They give you deep visibility into your endpoints while effectively identifying both known and unknown threats. Furthermore, you can quickly contain attacks that get through your defenses with automated response capabilities and hunt for hidden threats that are difficult to detect.

While EDR provides several benefits to customers, it has some drawbacks. Chief among them is that EDR security solutions are focused on monitoring endpoints only versus monitoring a broader environment. This means that EDR solutions don’t detect threats targeting other parts of your environment such as your network, email, or cloud infrastructure. In addition, not every organization has the security staff, budget, and/or skills to deploy and run an EDR solution. This is where MEDR solutions come into play.

What are Managed Endpoint Detection and Response (MEDR) solutions?

Managed EDR or MEDR solutions are EDR capabilities delivered as a managed service to customers by third-parties such as cybersecurity vendors or Managed Service Providers (MSPs). This includes key EDR functionality such as monitoring endpoints, detecting advanced threats, rapidly containing threats, and responding to attacks. These third-parties usually have a team of Security Operations Center (SOC) specialists who monitor, detect, and respond to threats across your endpoints around the clock via a ‘follow the sun’ approach to monitoring.

MEDR security solutions allow you to offload the work of securing your endpoints to a team of security professionals. Many organizations need to defend their endpoints from advanced threats but don’t necessarily have the desire, resources, or expertise to manage an EDR solution. In addition, a team of dedicated SOC experts with advanced security tools can typically detect and respond to threats faster than in-house security teams, all while investigating every incident and prioritizing the most critical threats. This enables you to focus on your core business while getting always-on security operations.

Similar to EDR though, one downside to MEDR security solutions is that they defend only your endpoints from advanced threats and don’t monitor other parts of your infrastructure. Moreover, while many organizations want to deploy EDR as a managed service, not everyone desires this. For example, larger and/or more risk-averse organizations who are looking to invest heavily in cybersecurity are typically satisfied with running their own EDR solution. Now, let’s discuss how to choose the right endpoint security solution when trying to defend your endpoints from threats.

Choosing the Right Endpoint Security Solution

As I mentioned in my previous blog, there isn’t a single correct solution for every organization. This logic applies to EDR and MEDR security solutions as well since each solution works well for different types of organizations, depending on their needs, resources, motivations, and more. Nevertheless, one major factor to consider is if you have or are willing to build out a SOC for your organization. This is important because organizations that don’t have or aren’t willing to develop a SOC usually gravitate towards MEDR solutions, which don’t require significant investments in cybersecurity.

Another factor to keep in mind is your security expertise. Even if you’re have or are willing to build a SOC, you may not have the right cybersecurity talent and skills within your organization. While you can always build out your security team, you may want to evaluate an MEDR solution because a lack of expertise makes it difficult to effectively manage an EDR solution. Finally, a common misconception is that you must choose between an EDR and a MEDR solution and that you cannot run both solutions. In reality, many organizations end up using both EDR and MEDR since MEDR solutions often complement EDR deployments.

I hope this information and key factors help you better understand EDR and MEDR solutions while acting as a guide to selecting the best endpoint security solution for your organization. For more details on the different cybersecurity acronyms and how to identify the right solution for your needs, stay tuned for the next blog in this series – Unscrambling Cybersecurity Acronyms: The ABCs of MDR and XDR Security. In the meantime, learn how Cisco Secure Endpoint stops threats with a comprehensive endpoint security solution that includes both advanced EDR and MEDR capabilities powered by an integrated security platform!

Unscrambling Cybersecurity Acronyms: The ABCs of Endpoint Security

By Nirav Shah

Ransomware and other advanced attacks continue to evolve and threaten organizations around the world. Effectively defending your endpoints from these attacks can be a complex undertaking, and a seemingly endless number of security acronyms only compounds that complexity. There are so many acronyms – EPP, EDR, MEDR, MDR, XDR, and more – for various cybersecurity products and services that it becomes difficult to understand the differences between them and choose the right solution for your organization. Deciphering all these acronyms is a task on its own and deciding which solution works best for you is even more challenging.

We here at Cisco believe that understanding these acronyms and determining which security products or services are the best fit for your organization’s needs doesn’t have to be so hard. That’s why we developed this blog – the first in a series – to give you an overview of the different types of threat detection and response solutions.

This series will help you understand the benefits and disadvantages of each solution, the similarities and differences between these solutions, and how to identify the right solution for your organization. Now let’s go over the different types of security solutions.

Overview of Threat Detection and Response Solutions

There are several types of threat detection and response solutions, including:

  • Endpoint Detection and Response (EDR) A product that monitors, detects, and responds to threats across your endpoint environment
  • Managed Endpoint Detection and Response (MEDR) A managed service operated by a third-party that monitors, detects, and responds to threats across your endpoint environment
  • Managed Detection and Response (MDR) A managed service operated by a third-party that monitors, detects, and responds to threats across your cybersecurity environment
  • Extended Detection and Response (XDR) A security platform that monitors, detects, and responds to threats across your cybersecurity environment with consolidated telemetry, unified visibility and coordinated response

These solutions are similar in that they all enable you to detect and respond to threats, but they differ by the environment(s) being monitored for threats, who conducts the monitoring, as well as how alerts are consolidated and correlated. For instance, certain solutions will only monitor your endpoints (EDR, MEDR) while others will monitor a broader environment (XDR, MDR). In addition, some of these solutions are actually managed services where a third-party monitors your environment (MEDR, MDR) versus solutions that you monitor and manage yourself (EDR, XDR).

How to Select the Right Solution for your Organization

When evaluating these solutions, keep in mind that there isn’t a single correct solution for every organization. This is because each organization has different needs, security maturities, resource levels, and goals. For example, deploying an EDR makes sense for an organization that currently has only a basic anti-virus solution, but this seems like table stakes to a company that already has a Security Operations Center (SOC).

That being said, there are a few questions you can ask yourself to find the cybersecurity solution that best fits your needs, including:

  • What are our security goals? Where are we in our cybersecurity journey?
  • Do we have a SOC or want to build a SOC?
  • Do we have the right cybersecurity talent, skills, and knowledge?
  • Do we have enough visibility and context into security incidents? Do we suffer from too many alerts and/or too many security tools?
  • How long does it take us to detect and respond to threats? Is that adequate?

Of these questions, the most critical are about your security goals and current cybersecurity posture. For instance, organizations at the beginning of their security journey may want to look at an EDR or MEDR solution, while companies that are further along their journey are more likely to be interested in an XDR. Asking whether you already have or are willing to build out a SOC is another essential question. This will help you understand whether you should run your security yourself (EDR, XDR) or find a third-party to manage it for you (MEDR, MDR).

Asking whether you have or are willing to hire the right security talent is another critical question to pose. This will also help determine whether to manage your cybersecurity solution yourself or have a third-party run it for you. Finally, questions about visibility and context, alert, and security tool fatigue, as well as detection and response times will help you to decide if your current security stack is sufficient or if you need to deploy a next-generation solution such as an XDR.

These questions will help guide your decision-making process and give you the information you need to make an informed decision on your cybersecurity solution.

Why CISOs Are Demanding Detection and Response Everywhere

By Leah MacMillan

Over the past three decades, we’ve had time at Trend Micro to observe the industry trends that have the biggest impact on our customers. And one of the big things we’ve seen is that threats move largely in tandem with changes to IT infrastructure. This matters today because most organizations are transforming the way they run and manage their infrastructure—a daunting task on its own.

But with digital transformation also comes an expanded corporate attack surface, driving security leaders to demand enhanced visibility, detection & response across the entire enterprise — this is not just about the endpoint.

Transforming business

Over the past five years, there has been a major shift in the way IT infrastructure is delivered, and with that shift, increasing complexity. A big part of this change has been the use of the cloud, reflected in Gartner’s prediction that the market will grow to over $266 billion in 2020. Organizations everywhere are leveraging the cloud and DevOps to rapidly deliver new and differentiated applications and services for their customers, partners and employees. And the use of containers and microservices across a multi-cloud and hybrid environment is increasingly common.

In addition to leveraging public cloud services like IaaS, organizations are also rapidly adopting SaaS applications like Office 365, and expanding their use of mobile and collaborative applications to support remote working. Some are even arguing that working patterns may never be the same again, following the changes forced on many employers by the Covid-19 pandemic.

Combine these changes with networks that continue to extend to include branch offices and add new areas to protect like operational technology including industrial systems, and we can certainly see that the challenges facing the modern enterprise look nothing like they did a few years ago.

Under fire, under pressure

All of these infrastructure changes make for a broader attack surface that the bad guys can take advantage of, and they’re doing so with an increasingly wide range of tools and techniques. In the cloud there is a new class of vulnerabilities introduced through a greater use of open source, containers, orchestration platforms, supply chain applications and more. For all organizations, the majority of threats still prey upon the user, arriving via email (over 90% of the 52.3 billion we blocked in 2019), and they’re no longer just basic phishing attempts. There’s been an uptick in fileless events designed to bypass traditional security filters (we blocked 1.4 million last year). And Business Email Compromise (BEC) and ransomware continue to evolve, the latter causing major outages across local government, healthcare and other vulnerable sectors.

Organizations are often left flat-footed because they don’t have the in-house skills to secure a rapidly evolving IT environment. Mistakes get made, and configuration errors can allow the hackers to sneak in.

Against this backdrop, CISOs need visibility, detection and response capabilities across the extended enterprise. But in too many cases, teams are struggling because they have:

  • Too many security tools, in silos. Security leaders want to consolidate the 10, 20 or even 50+ security technologies currently in use across their organizations. And ideally, they need capabilities that work seamlessly together, sharing threat intelligence across security layers, and delivering a fully connected threat defense.
  • Too few people. Global cybersecurity skills shortages have now exceeded four million, with existing teams often overwhelmed by alerts, allowing serious threats to fly under the radar
  • Increased compliance pressures. CISOs are under pressure to comply with a number of regulations, and the impacts of non-compliance are increasingly strict. While newer, more demanding compliance requirements like GDPR and the California Consumer Privacy Act aim to protect data, they also present operational challenges for cloud teams with complex, manual and time consuming audits. Not to mention new regulations have teeth, with fines that can have a serious impact on the bottom line.  For example, as of March 2020, 227 GDPR fines had been levied, totalling over 466 million euros.

Beyond the endpoint

While endpoint detection and response (EDR) has become a popular response to some of these problems over recent years, the reality is that cyber-attacks are rarely straightforward and limited to the endpoint (as noted in the email statistic above). Security teams actually need visibility, detection, and response across the entire IT environment, so they can better contextualize and deal with threats.

This is what Trend Micro XDR offers. It provides visibility across not just endpoints but also email, servers, cloud workloads and networks, applying AI and expert security analytics to correlate and identify potential threats. The result is fewer, higher fidelity alerts for stretched IT security teams to deal with. Recognizing the skills shortage reality, we also offer a managed XDR service that augments in-house SOC activities with the power of Trend Micro security experts.

Detection and response is too important to be limited to the endpoint. Today’s CISOs need visibility, detection, and response everywhere.
