Microsoft Purview: Credential scanning in Data Security Posture Agent

Microsoft Purview's Data Security Posture Agent will add a credential scanning feature by mid-2026, using LLM-powered detection to find exposed credentials like Entra ID credentials, private keys, and API tokens. It provides risk scores, AI insights, and a task board for managing findings.

[Introduction]

We are expanding the Data Security Posture Agent in Microsoft Purview with a new credential scanning capability. This update helps your organization discover exposed credentials and related data security risks across scoped locations. The agent analyzes selected data locations to detect sensitive credential types—including Microsoft Entra user credentials, private keys, and API tokens—and provides risk scores, AI-generated insights, confidence ratings, and credential categories so you can review, confirm, and take action from a single task board view.

This message is associated with Microsoft 365 Roadmap ID 558436.
