On Microsoft’s Lousy Cloud Security

schneier.com·Apr 9, 2026

In 2024, federal cybersecurity evaluators criticized Microsoft's cloud offering for inadequate security documentation, yet the Federal Risk and Authorization Management Program (FedRAMP) controversially approved it, allowing Microsoft to expand its government business despite security concerns.

The key insight for you is the significant risk and compliance issue highlighted by the federal cybersecurity evaluators' inability to verify Microsoft's cloud security due to inadequate documentation. Despite these concerns, FedRAMP authorized the use of Microsoft's Government Community Cloud High, indicating potential vulnerabilities in the federal approval process and underscoring the critical need for thorough security documentation and transparency in cloud offerings. This situation emphasizes the importance of rigorous third-party audits and the potential pitfalls of reliance on government certification alone for assessing cloud service security.
