Microsoft Bolsters Security Portfolio with AI Agent Management and Data Protection Updates

Microsoft has released several updates to its security portfolio in September 2026. One of the key updates is related to AI agents, which are now running on employee devices, cloud platforms, and across developer workflows.

These agents need to be monitored by security teams, who must govern what they can access and contain them when something goes wrong. The company's updates aim to help organizations discover and control local AI agents, extend Zero Trust to agent traffic, and strengthen the security operations center (SOC) foundations that AI-era operations depend on.

The updates also include enhancements to Microsoft Purview and Entra Global Secure Access, which bring data security to the network across human actions and agentic traffic. This means organizations can discover sensitive files and text in real-time and block them from being shared to risky destinations.
