GCC High Priority Update
Week of June 25, 2026
Microsoft Purview Endpoint DLP is expanding to monitor and protect sensitive data transferred from managed endpoints over FTP and SFTP, closing a long-standing gap in data exfiltration coverage. Organizations gain visibility into file transfers using these protocols and can apply DLP policies to prevent unauthorized movement of sensitive content, extending the same level of control already in place for other data channels. For GCC High environments where data leaving the boundary through less-monitored pathways is a real compliance risk, this update brings file transfer protocols under the same governance umbrella as email, SharePoint, and OneDrive. The feature is currently in development and expected to begin rolling out in August 2026.
