The Challenge

Required FedRAMP High alignment for Microsoft Copilot deployment. Controlled Unclassified Information (CUI) handling mandated strict data classification. Existing M365 tenant had 4 years of ungoverned SharePoint growth with no sensitivity labels.

The Solution

Performed a comprehensive CUI audit and classified 2.3 million documents using automated sensitivity labeling. Implemented NIST 800-171 controls mapped to Microsoft Purview policies. Deployed Copilot in GCC High with custom DLP rules preventing CUI from appearing in AI-generated responses to unauthorized personnel.
