You know how the old saying goes. Modern problems require modern solutions. As cyber attackers become shrewder in taking advance of the available technology, the need for robust cybersecurity solutions increases. Here is where XDR comes in.

But what is XDR? How does it work and what does it bring to the table? Is it the best option out there? Keep reading to find out!

What is XDR?

Allow me to kick off this article by answering the very question that spurred its creation: what is XDR? The acronym stands for extended detection and response, embodying a type of cybersecurity solution that both monitors and mitigates incidents. As for a proper definition, global research and advisory firm Gartner describes XDR as:

a SaaS-based, vendor-specific, security threat detection and incident response tool that natively integrates multiple security products into a cohesive security operations system that unifies all licensed components.

What sets extended detection and response apart from traditional cybersecurity solutions is its ability to deliver real-time information on threats, which allows you to go beyond standard controls. Simply put, XDR is a holistic approach to IT infrastructure that provides a more well-rounded view of the entire network.

XDR Features

Now that we’ve established what XDR is, let’s continue the discussion by seeing what it does. Designed to improve an organization’s cybersecurity, it has several functions that you can add to your digital defense strategy. Here are the main features of an XDR solution:

  • cyberattack detection and response,
  • comprehensive behavior analysis,
  • shared threat intelligence (both internal and external),
  • automatic alert confirmation,
  • complete data integration,
  • all in a unified interface.

XDR Benefits

What is XDR good for? What are the advantages it brings to your enterprise, should you choose to opt for this cybersecurity approach? enhanced endpoint detection and response capabilities improved operational productivity, and reduced costs slash resource usage.

a. Enhanced EDR Capabilities

As the acronym suggests, XDR is one step above traditional endpoint detection and response. It beneficially impacts four areas of EDR that are specific to your company’s Security Operations Center (SOC): detection, hunting, investigation, and recommendation.


Through endpoint telemetry and an AI-driven list of cybersecurity threats to compare traffic against, XDR has the aptitude to identify not only more threats but advanced ones as well.


An XDR solution does more than just detect known threats. It actively hunts and analyzes suspicious online behaviors to discover previously unknown malicious domains and cyberattacks.


Pairing XDR with a dedicated information security team within your company creates a strong human-machine correlation that will result in expert incident investigations.


Finally, the data gathered by XDR can also provide your IT team with proactive recommendations that will greatly minimize the risks of future attacks.

b. Improved Operational Productivity

One of the main points of interest presented by XDR is represented by the fact that it unites multiple solutions under one accessible interface. This means that your SOC will be able to handle every step in the cybersecurity process in one place, which is advantageous towards the overall productivity index of the enterprise. Not only will this benefit your information security team, but other employees working on the company endpoints as well.

c. Reduced Costs and Resource Usage

Another plus of unifying all the moving parts of your digital defense in one dashboard is the reduction in operational costs and resource usage. Not only will you save your employees a lot of time, but you will also save the company money as well. What is more, XDR is usually lighter on the system than separate solutions that operate out of independent platforms, so there’s that as well.


Before concluding this article, there is one more important question I want to raise: what is XDR’s value in the context of today’s cybersecurity landscape? Is it the optimal solution in 2021 and beyond? The short answer here is (unfortunately) no. Let’s see why.

Although the query of what is XDR can be easily answered by saying it is the more advanced version of traditional EDR, that doesn’t mean it’s the most cutting-edge one out there. The current golden standard is EPDR, which stands for endpoint prevention, detection, and response.

EPDR is the industry’s natural response to the technological advancements taking place behind enemy lines. As hackers become more cunning and the inner workings of cyberattacks progress, so must we. And regrettably, standard EDR or XDR just don’t cut it anymore. Prevention is more efficient than detection and response these days, and that’s exactly what EPDR brings new to the table.

Wrapping Up…

So, what is XDR? A more modern take on traditional EDR, it extends your company’s detection and response capabilities, thus offering a higher degree of protection as well. However, its defensive qualities fall short in the face of robust solutions such as EPDR, which focuses on it as the primary step of a cybersecurity strategy.
