EDR (Endpoint Detection and Response)

EDR (Endpoint Detection and Response) collects endpoint activity to detect, investigate and respond to suspicious behaviour on computers, servers or other supported devices. It may correlate processes, files, network activity and identity and provide isolation or remediation actions, depending on the product and permissions. EDR extends traditional prevention but does not guarantee real-time detection or complete coverage. Unmanaged devices, disabled agents, unsupported systems and poorly tuned rules create gaps. Deployment should define assets, policies, retention, privacy, response authority, exceptions and integration with incident handling. Teams need to test safe scenarios, monitor agent health and review false positives. An alert is not a resolved incident, and “zero detections” is meaningful only when telemetry coverage and the detection pipeline are known to be healthy.
