Microsoft has made Microsoft Purview and Microsoft Entra Global Secure Access generally available for network-level data security that covers both human actions and agents acting on a user's behalf, the company said on 24 September 2026.
Purview classification and policies are enforced by Entra at the network layer, so organisations can detect sensitive files and text in real time and block them from going to risky destinations. Microsoft's example is an employee or on-behalf-of agent trying to upload a sensitive document to an unsanctioned AI tool, where the policy can stop the transfer before the data leaves.
The update was part of Microsoft's September security round-up, which said the month's changes help customers discover and control local AI agents and extend Zero Trust to agent traffic. Other additions include an AI-generated email detonation summary for customers using both Defender and Security Copilot, Purview eDiscovery support for content from Copilot Pages, Copilot Notebooks and Loop, and an option to archive inactive SharePoint content so it drops out of Microsoft 365 Copilot indexing.
Microsoft did not give pricing for the new capabilities in the post.
