Narrative intro

Security Operations is the cluster that determines whether the rest of the cloud estate is defensible. This map names the cluster's load-bearing pieces: the Sentinel + Defender XDR pairing, the detection engineering discipline, the Entra ID P2 + Identity Protection layer, and the operational maturity cadence underneath all three. The SKUs are stable; the capability grows over years.

Key takeaways

  • Sentinel + Defender XDR is the canonical SOC pairing, not either/or
  • Detection engineering is the compounding discipline — the multiplier across years
  • Entra ID P2 + Identity Protection produce the highest-value SOC inputs
  • Operational maturity is the cadence under the metric — incident review, runbook refinement, MITRE coverage
