What is Extended Detection and Response?

Also known as: XDR

Extended detection and response is an approach that correlates security telemetry across multiple layers, such as endpoints, network, email, and cloud, into a unified detection and response platform. It matters because attacks often span several domains, and combining signals reduces blind spots and speeds investigation.

Example

XDR links a suspicious email, a resulting endpoint infection, and unusual cloud logins into a single correlated incident for analysts.
