The Hidden Steps Microsoft Forgot to Document: Securing Azure App Service Authentication Behind Front Door with Private Link
Today I want to walk through how to configure Azure App Service Authentication when your App Service sits behind Azure Front Door and is accessed through a Private Link. On a dreadful day in october 2025, I received something that most IT people fear - a request from a client!

Microsoft Entra Restricted Management Administrative Units: Delegating Control Without Sacrificing Security
Today, I’ll take a closer look at Microsoft Entra Administrative Units (AUs) and Restricted Management Administrative Units (RMAUs) Despite being incredibly useful, AUs and RMAUs are still underutilized in many environments.

The way Elevated Access currently works, there’s no built-in way to manage, or restrict it—not through PIM for time- and approval-based access, not with access reviews, and not with entitlement management either. Once access is enabled for a user,
