EDR XDR Endpoint Response

EDR (Endpoint Detection & Response) and XDR (Extended Detection & Response) are cybersecurity platforms that continuously monitor devices for threats and orchestrate rapid response. EDR focuses on individual endpoints (computers, servers, mobile devices). It collects telemetry—processes, network connections, file activity, registry changes—and compares against known malware signatures and behavioral patterns. When suspicious activity is detected, EDR alerts security teams or can take automated actions (kill process, block network, isolate endpoint). XDR extends this beyond endpoints. It correlates signals from networks, email, cloud, identity systems, and applications. A single attacker might move from phishing email → compromised account → endpoint lateral movement → cloud data exfiltration. XDR connects these dots automatically. Senior teams use XDR to stop breaches at stage 1 (email block) instead of stage 4 (data loss).
