EDR stands for Endpoint Detection and Response. It is a class of security solutions designed to monitor endpoints such as desktops, laptops, servers, and mobile devices for signs of malicious activity and to provide detection, investigation, and automated or assisted response. EDR emphasizes continuous data collection, behavioral analytics, and rapid containment to reduce dwell time of threats, complementing or replacing traditional signature-based antivirus approaches.

Core capabilities typically include data collection from endpoints (process creation, file and registry changes, network connections, memory activity, and lateral movement indicators), real-time or near-real-time analytics, and alert generation. Many EDR tools use machine learning and behavior-based detection to identify novel or obfuscated threats. Telemetry and cloud-based analytics enable cross-device correlation, historical investigation, and risk scoring. Automated responses can include isolating a host, terminating a malicious process, quarantining files, or blocking network activity, while human-led investigations leverage incident timelines, evidence trails, and enrichment from external feeds.

Operational workflows in EDR usually involve detection, alert triage, and investigation, followed by containment, remediation, and recovery actions. EDR often integrates with security information and event management systems, security orchestration, automation, and response platforms, and can feed into broader strategies such as extended detection and response (XDR) and threat-hunting programs. Many organizations map detections to frameworks like MITRE ATT&CK to understand adversary techniques and guide response.

Deployment considerations include endpoint coverage, performance impact, data privacy and retention, and the need for skilled analysts. EDR is commonly deployed on workstations, servers, and mobile devices, and is a core component of modern endpoint security architectures.
