What is XDR in Cybersecurity?
Extended Detection and Response. A security platform that unifies telemetry from endpoints, networks, cloud workloads, email, and identity systems into a single detection and investigation experience. XDR correlates alerts across these data sources to surface attacks that individual tools miss when operating in isolation.
