Uncover sensitive data, surface your biggest risks, and drive action. Start with the Data Security Posture and Triage Agents. youtu.be/BqMFzvk7T38 Cut through alert noise and focus on the risks that matter with Agents in Microsoft Purview. Use Data Security Triage Agent to prioritize incidents, investigate user activity with full context, and uncover hidden patterns that signal real threats. Identify and act on high-risk behavior, like data exfiltration or persistent access, before it leads to data loss. #AgentsinPurview #purview #datagovernance #microsoft #microsoft365 #microsoftsecurity

As agents evolve, security teams have to keep up.
That’s why we’re expanding Agent 365 to include:
✅ Visibility into AI-related risk across the org and app estate
✅ Securing identities with continuous, risk‑aware access
✅ Blocking sensitive information from being used in prompts
And more. Learn more: msft.it/6014Qqv6G
