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.
