Gartner defines Extended Detection and Response (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. XDR represents a new security paradigm in which individual security controls see, share, and correlate data as part of a coordinated security platform to more effectively detect threats and to then deliver a coordinated response that covers the entire attack surface. Defending against todays sophisticated threats requires visibility and control that spans the entire distributed network.”]
