EDR (Endpoint Detection and Response) is a class of security software that records and analyzes activity on endpoints such as process creation, file changes, command execution and network connections. It helps security teams investigate and contain suspicious behavior after prevention alone is insufficient.

It helps security teams investigate and contain suspicious behavior after prevention alone is insufficient.

Its advantage over an isolated antivirus is richer temporal evidence, with no clairvoyance involved: which process spawned which child, touched which file and contacted which host. That sequence is the telemetry from which behavioral detection infers suspicious behavior, and it can expose an adaptive attack whose individual artifacts appear harmless. XDR extends the same correlation beyond the endpoint, into identity, cloud, network and messaging.

An endpoint stops being a black box and becomes a timeline.
