Introduction
We are introducing inline file upload protection for Microsoft Edge for Business to help prevent data leakage when users upload files to consumer generative AI (GenAI) apps in the browser. This complements the existing text upload protections available today for unmanaged GenAI apps and can be layered with Endpoint DLP protections. With this update, admins can detect and enforce inline protections on file uploads in Edge for Business. Policies can target file-specific conditions such as file size, file type, and sensitive information types, enabling organizations to audit or block activities for users on Intune-managed Windows devices.
This message is associated with Microsoft 365 Roadmap ID 518642.
When this will happen
- Public Preview: Begins late November 2025 (previously mid-November); expected to complete by early December 2025.
- General Availability (Worldwide): Begins mid-January 2026 (previously early December 2025) (previously late November); expected to complete by end of January 2026 (previously mid-December 2025).
How this affects your organization
- Who is affected: Admins managing Microsoft Purview DLP policies and Edge for Business on Intune-managed Windows devices.
- What will happen:
- Admins can extend existing Purview collection and DLP policies to include file upload protection for unmanaged GenAI apps.
- Inline protections are built directly into Edge for Business.
- Automated behaviors will block use of unprotected browsers for users included in blocking policies.
- Policies can be configured based on file size, type, and sensitivity.
What you can do to prepare
- No action is required before rollout.
- Review your current collection and DLP policies.
- Update policies to include file upload conditions if needed.
- Inform your Security and Edge admins about this enhancement.
