Data Security Investigations in Microsoft Purview

Identify what data was exposed in a breach, not just where it moved, but what it contains, how sensitive it is, and the risk it creates using Microsoft Purview Data Security Investigations. Search across massive volumes of files using natural language, pinpoint the highest risk content, and connect it to user activity to see the full scope of an incident. Investigate and act in one workflow. Analyze content deeply across files, emails, and AI interactions, uncover hidden or unclassified sensitive data, and contain exposure fast. Proactively identify risks, respond to incidents with clarity, and mitigate impact before it spreads. Christophe Fiessinger, Microsoft Purview Principal Squad Leader, joins Jeremy Chapman to walk through real-world investigation workflows—from scoping and analysis to mitigation and automation—so you can move faster and make more informed security decisions. ► QUICK LINKS:  00:00 - Keep data safe with DSI 01:26 - Connect dots between data risk & impact 02:47 - Built-in AI 03:47 - Work across the full lifecycle of an incident 04:56 - Create an investigation 06:36 - Deep search and analysis 09:03 - How DSI helps data leaks 10:40 - Contain risk with built-in mitigation 11:32 - Automate using agents 13:23</
