More information
What and why
We're introducing Insider Risk Management (IRM) triage agent summaries in Microsoft Defender. This enhancement helps investigators review key risk insights directly from the Defender alert queue, reducing the need to switch between security tools during alert triage.
When the IRM triage agent is enabled and Insider Risk Management alerts are shared with Microsoft Defender, supported alerts will include AI-generated summaries such as alert categorization, investigation findings, observed risk patterns, and relevant user context. Investigators can continue to access the complete investigation experience in Microsoft Purview for deeper analysis.
This message is associated with Microsoft 365 Roadmap ID 567472.
