Extended Detection and Response (XDR) is a method of detecting and responding to threats, eliminating the challenges of traditional security silos, thus enabling the delivery of more effective protection against cyberattacks and unapproved access.
Forrester Research defines XDR as: “The evolution of EDR, which optimizes threat detection, investigation, response, and hunting in real time. XDR unifies security-relevant endpoint detections with telemetry from security and business tools such as network analysis and visibility (NAV), email security, identity and access management, cloud security, and more. It is a cloud-native platform built on big data infrastructure to provide security teams with flexibility, scalability, and opportunities for automation.”
