What Is Extended Detection and Response (XDR)?

What Is Extended Detection and Response (XDR)?

For many decades now, emerging threats have put organizations at risk. As the IT landscape evolved and threat actors found new ways to attack, security teams needed to find new ways to detect and respond to threats.


Today, this evolving theme of complexity continues. And the list of point solutions being deployed to overcome these burgeoning threats goes on and on — from SIEM, to cloud workload protection, to endpoint detection and response (EDR), to network detection and response (NDR) and more. While these investments each do their part to solve immediate and dire issues, in combination they’ve created a bigger challenge: how to use and get value from them together.


This is why we call them point tools; they were made to address specific challenges. Now that teams face a myriad of challenges, it’s never been more critical to have them work in concert. Without doing so, limited security operations center (SOC) resources will continue to be spread thin, total cost of ownership will continue to increase and the process of pinpointing and responding to threats will continue to be time-consuming and inefficient.


Extended detection and response (XDR) is the beginning of a shift towards uniting multiple siloed solutions and reducing the complexity that impedes fast detection and response. As stated in the blog Gartner Top 9 Security and Risk Trends for 2020: “The primary goals of an XDR solution are to increase detection accuracy and improve security operations efficiency and productivity.” Gartner identified XDR as the number one security and risk trend at the end of 2020, suggesting now is the moment when all this complexity — too many tools, too many alerts, too little time — is coming to a head, with X ..
