Microsoft Sentinel Baseline Deployment: From Zero to Operational SOC

Microsoft Sentinel can be enabled in minutes. A good Sentinel deployment takes planning. Most Sentinel pain does not come from missing detections or weak analytics. It comes from architectural shortcuts taken on day one: poorly scoped workspaces, uncontrolled access, unpredictable ingestion costs, and a lack of governance before the first alert ever fires.

In this series first post, we walk through a clean baseline Sentinel foundation, following Microsoft Learn guidance and real-world operational best practices. We’ll design the workspace correctly, secure it properly, and configure it so future growth is intentional—not accidental.
