Microsoft Sentinel Planning Guide
A planning guide for evaluating whether and how to adopt Microsoft Sentinel.
Step 1 — Confirm the Gap
Identify the specific gap Sentinel would close — non-Microsoft data sources, extended retention, or custom detection rules — rather than adopting it as a general "more tooling" decision.
Step 2 — Scope Data Sources
List data sources beyond Defender XDR that need correlation.
Estimate ingestion volume to project ongoing cost.
Step 3 — Staffing Plan
Confirm internal analyst time, or select a managed detection and response provider.
Define an alert review cadence before go-live, not after.
