Goodbye Oversharing: How to Detect, Mitigate, and Prevent It!

Everyone talks about oversharing, but not many know how to actually detect, mitigate, and prevent it using only Microsoft’s built-in tools. Oversharing in Microsoft 365 Copilot and Copilot Agents is more than just a buzzword; it is a daily challenge for organizations of all sizes. In this session, I will share a proven process that has helped customers secure hundreds of terabytes of data across different industries and environments. You will learn how to identify oversharing risks with SharePoint Advanced Management, Purview, and PowerShell, and how to prioritize and remediate risky sites and files using practical reporting and workflows. I will show you how to set up sensitivity labels, data loss prevention policies, and automated permission hygiene for ongoing control. Copilot is not just part of the challenge; it is also a powerful tool that makes governance work easier and more efficient. Instead of live demos, you will get real-world examples, reporting templates, and actionable steps you can put to use right away. Whether you are preparing for your first Copilot or Agent rollout or scaling up, you will leave this session with the confidence and tools to beat oversharing, starting today.
