GCC Priority Update
Week of October 15, 2026
Microsoft Purview Endpoint Data Loss Prevention is expanding to monitor and protect sensitive data transferred from managed endpoints over FTP and SFTP, closing a gap where file transfer protocols operated outside DLP policy coverage. Organizations can now detect and prevent unauthorized movement of sensitive content through these channels — extending the same visibility and enforcement already in place for email, SharePoint, and OneDrive to a transfer pathway commonly used for large file movement and legacy system integrations. For GCC organizations where endpoint data protection is a compliance requirement, this update brings FTP and SFTP transfers under centralized Purview governance. The feature is currently rolling out for GCC environments.

Microsoft Purview: Insider Risk Management – Enhanced user profile in IRM alerts
We’re enhancing the User section within Insider Risk Management alerts to provide investigators with more contextual user profile and risk attributes directly within their workflow. With this update, analysts can now view key user details such as employee type, office location, start date, policy inclusion, priority user group status, and last working day—helping them build a more complete understanding of the user during investigations without navigating away from the alert experience. This feature will be available as part of the new alert workflow through the Alert Details panel. Additional user attributes will continue to be introduced over time, with pseudo-anonymization honored to support privacy-by-design investigation practices. Microsoft Purview Insider Risk Management correlates various signals to identify potential malicious or inadvertent insider risks, such as IP theft, data leakage, and security violations. Insider Risk Management enables customers to create policies based on their own internal policies, governance, and organizational requirements. Built with privacy by design, users are pseudonymized by default, and role-based access controls and audit logs are in place to help ensure user-level privacy.

By centralizing investigation history directly within alerts, this update helps improve collaboration and ensures all stakeholders stay aligned throughout the investigation lifecycle. These note enhancements will also be made available in Cases.
