Securing Azure Tenants for Government Agencies

I recently transitioned into a role focused on security auditing for major government agencies. Those who follow my work know that large scale security and deployment have always been my areas of focus—but working with government tenants has offered new insights into how cybersecurity professionals can effectively secure Azure at scale.

Government Azure tenants operate at a higher security baseline than commercial ones. Any system deployed must obtain an Authority to Operate (ATO), a rigorous process ensuring applications, virtual machines, and supporting infrastructure comply with federal standards such as FedRAMP and CISA guidelines.

Before deployment, federal agencies must audit each application against these standards. The process typically begins with mapping configurations to the CIS Controls (Version 3) for Azure tenants. Each control must be validated—from enforcing multi factor authentication to denying public access and ensuring compliance with both CIS and agency specific baselines.

To conduct these assessments efficiently, automation is essential. Tools like Azure Resource Inventory (ARI), a Microsoft approved PowerShell module, provide detailed resource inventories and surface security configurations across subscriptions. Meanwhile, Azure Monitor can benchmark tenant configurations against Microsoft best practices, producing automated compliance reports that highlight deviations.

Given the scale of government environments—with tens of thousands of users and complex dependencies, manual validation is impractical. Automation ensures continuous compliance visibility and reduces audit fatigue.
