What is XDR?

Answer 1

XDR DRAM or extreme data ratedynamic random access memory is a high-performance RAM interface and successor to the Rambus RDRAM it is based on.

Answer 2

XDR (Extended Detection & Response) is an evolution of threat detection and incident response (TDIR) that successfully breaks down the traditional data and environment silos of legacy SecOps platforms to deliver wider attack surface visibility, deeper threat detection – and ultimately, faster incident response. XDR does not necessarily mean other security controls are rendered obsolete. Rather, XDR platforms must ingest, normalize, and correlate telemetry from all sources such as SIEM, EDR, and UEBA to reduce noise, identify true Indicators of Compromise (IoCs), trigger appropriate automated response, and deliver actionable alerts.
