Evolving Enterprise Security with Microsoft Purview

In this AI Agent & Copilot Minute, Mason Siefert explains how Microsoft is evolving enterprise security from simple risk detection to AI‑driven risk investigation and response using Purview and Sentinel.

Key Takeaways

• Growing security needs: Microsoft leads in risk detection with tools like Defender XDR, but as enterprise data environments grow in scale and complexity, organizations now need AI‑driven security that can investigate and manage risk across the entire data estate.
• Purview investigations: Through the January 2026 general release of Purview Data Security Investigations, Microsoft addresses the challenge of overwhelming data volumes by using generative AI to automatically analyze security and summarize underlying risks so security teams can act more confidently.
• Capabilities: Specifically, Purview enables these outcomes through built-in capabilities that analyze risk at scale, including content risk examination with scoring and remediation guidance, vector search for non‑keyword discovery, and automatic categorization by risk, sensitivity, and subject to speed incident analysis.
• Risk identification: Purview integrates with Microsoft Sentinel’s graph to visually connect users, data, and activities across incidents and enables immediate mitigation, and security teams are able to identify and contain risks quicker.
