Security groups have always been one of the most critical pieces of access control in Microsoft Entra.
They control access to Azure subscriptions, SharePoint sites, Power BI reports, enterprise apps, and more.
But unlike Microsoft 365 Groups, security groups didn’t support sensitivity labels – leaving admins to rely on approval workflows, custom automation, or post-creation audits to prevent oversharing.

A few benefits:
🔹 Reuse existing Purview sensitivity labels
🔹 Prevent unauthorized guest access before it happens
🔹 Apply consistent governance across group types
🔹 Enable safer self-service group creation
🔹 Build a foundation for future AI and agent governance
One thing I found interesting is the shift from reactive governance to proactive protection. Instead of finding risky group memberships later, organizations can enforce policies at the point of creation.
