XDR: Extended Detection and Response in Cybersecurity
XDR stands for Extended Detection and Response. XDR unifies telemetry from endpoints, networks, cloud workloads, and email into a single detection and response platform. It correlates signals across multiple security layers to surface threats that siloed tools miss.
How XDR Is Used in Cybersecurity
Security engineers deploy XDR to consolidate detection across their environment and reduce tool sprawl. SOC analysts benefit from correlated alerts that provide full attack context without manual pivoting. Incident responders use XDR's cross-layer visibility to trace an attacker's movement from initial access to lateral spread.
