Defender XDR in the Real World: Measurable Risk Reduction
summary
Claims a four‑stage pipeline that cuts MTR by turning noisy alerts into correlated incidents then automating enrichment, adding AI summaries, and measuring impact. Uses Defender XDR incident correlation, Sentinel fusion, Azure Monitor smart groups, Logic Apps playbooks and Security Compilot for summaries called from playbooks. Cites 3,832 alerts/day and 62% unattended as the scale problem. Built reversible containment, read‑only enrichment, automated routing, and a scorecard that reports MTR, incidents by severity and time saved by automation.
