Data Security Posture Agent is now available in preview [MC1217155]

Message ID: MC1217155

[Introduction]

We’re introducing the Data Security Posture Agent, available in public preview December 24, 2025. This agent helps data security admins proactively discover sensitive data across your organization’s data estate and assess associated risks. By leveraging large language models (LLMs), it goes beyond traditional keyword-based analysis to understand the purpose and context of content, enabling more accurate risk identification and actionable insights.

This message is associated with Roadmap ID 542188.

[When this will happen:]

• Public Preview (Worldwide): Rollout begins mid-December 2025 and completes by late December 2026.
• General Availability (Worldwide): Rollout begins mid-March 2026 and completes by late March 2026.

[How this affects your organization:]

Who is affected: Admins managing data security and compliance in Microsoft Purview.

What will happen:

• A new Data Security Posture Agent will be available in Microsoft Purview under the Explore Agent tab.



• The agent uses LLM-powered natural language discovery to:
  • Search documents, emails, and messages for sensitive data.
  • Assess risks based on context and intent, not just keywords.
• Provides:
  • GenAI-generated summaries.

  

  • LLM-assisted job completion tasks.
