You could ask ten security professionals in a room what eXtended Detection and Response (XDR) is and you would get ten different answers.

According to Gartner, “XDR is a unified security incident detection and response platform that automatically collects and correlates data from multiple proprietary security components.”

Seems simple, in theory, yet there is so much confusion in the market about what exactly an XDR solution looks like

This is because eXtended Detection and Response (XDR) is a subjective set of processes, tools, and people established to provide new efficiencies in the traditional security operations center (SOC) by better integrating security control data and operations through cloud-based analytics, detection, and response.


The Varied Perspectives of XDR

Since XDR has no direct definition, its meaning varies from vendor to vendor. With this in mind, it also means that each vendor offers a different set of solutions they claim to be XDR. For example:

  • Some companies may sell just the tech stack
  • Some manage an existing tech stack
  • Some may view their XDR offering as less about technology and more about a comprehensive approach aimed at connecting multiple data sources to drive toward prevention

Really, XDR is simply a collection of cybersecurity tools that bring together control points, security data, analytics, and operations into a unified business solution. Each tool covers a different aspect of cybersecurity and optimizes detection, prevention, and data collection. In short, in order for something to be “XDR,” it should probably have the following:

  • Centralization of normalized data
  • Correlation of security data and alerts
  • A centralized incident response capability


Endpoint Detection and Response (EDR) is the process of managing and mitigating cyber threats based on end-point-level behaviors and data. XDR is a more advanced security solution than EDR offerings, with the capability to identify and neutralize threats. The service employs experienced, high-skill-level analysts with a more comprehensive roster of cutting-edge security tools at their disposal. This provides an enhanced level of proficiencies that go beyond the scope and cost-effectiveness of most internal security budgets, resources, and personnel.

Managed Detection and Response (MDR) and eXtended Detection and Response (XDR) both aim to detect and eliminate malware users; however, XDR advances these services by combining these tools, people, and processes that MDR might utilize separately. As cybersecurity continues to progress, XDR leads a new mindset towards prevention, while MDR remains a singular step within this process.

Why Companies are Moving toward XDR

  • CISOs are under pressure to move from reactive to proactive cybersecurity strategy – XDR  integrates tools and operations that eliminate any areas of weakness within your security,  preventing malware users from reaching your organization in the first place.
  • CISOs want to automate what they can within security operations – XDR solutions can offer real value in improving security operations productivity with alert and incident correlation, as well as built-in automation. 
  • XDR enables companies to get a more comprehensive view of their attack  surface – Gain a broader outlook on where you stand within the digital landscape in order to better understand your cyber strengths and weaknesses.
  • Contextualizing raw data – Many XDR solutions reduce complexity through the logical convergence of multiple systems, particularly Security Incident and Event Management (SIEM) tools and MDR.

XDR and your Managed Security Service Provider (MSSP)

The role of an MSSP is to monitor, manage, and improve a company’s cybersecurity posture. That said, the scope of a managed security service provider is much greater than that of just MDR or XDR. 

A MSSP should have a well-equipped, fully staffed security operations center (SOC), including security platform administrators, security analysts, malware analysts, a threat intelligence lab, and incident response analysts. All of these members should also be equipped with the right technology (typically a SIEM-based platform). In general, an MSSP has the capability to provide MDR, EDR, and XDR functions as a whole package.

How Avertium Sees XDR: (Av)XDR

Rather than building an eXtended Detection and Response (XDR) platform that is limited to the technology of the vendor and the development of the vendor’s tools, Avertium approaches XDR as a philosophy that was born from a simple concept: You cannot protect what you cannot see. 

(AV)XDR is first and foremost a methodology born of a mindset around the art of hunting the threat. It has arisen from our belief that in order to protect yourself, you must show no weakness toward those who might attack you.

 The Art of War: Know Thyself, Know Thy Enemy

Avertium’s approach to eXtended Detection and Response (XDR) incorporates security tools, experienced personnel, and proprietary processes that cover all aspects of your environment and then moves beyond security tools to include non-security data that provides deeper insights into threat behavior. Entering this insight into our Cyber Fusion Engine helps us to contextualize data and understand the relationships between seemingly disconnected events occurring across separate points in your business.

As a result, this offers an informed view of your business by looking at all of your points of vulnerability from the perspective of an attacker and the tactics and techniques they might use against you.

(AV)XDR employs XDR NOT as a set of tools or technologies, but as a philosophy, making our version of eXtended Detection and Response (XDR):

  • Open and modular
  • Designed to leverage advanced AI and analytics
  • Tuned to detect and protect against highly relevant threat actor tactics and techniques
  • Designed to utilize enterprise-grade workflows and remediation
  • Constructed for your unique environment and business needs
