Session Abstract

You can’t stop users using AI, but you can control what happens to your data. Microsoft 365 Copilot and generative AI tools are changing how data is shared, introducing new risks of sensitive information being exposed through AI interactions. This session shows how to use Microsoft Purview Data Loss Prevention (DLP) to control how data is used in Copilot and AI applications. You will learn how to identify sensitive data, design effective DLP policies, and apply controls across Microsoft 365, endpoints, browsers, and AI tools. We will focus on preventing sensitive data from being copied, uploaded, or shared with AI, while still enabling productivity. You will also see how DLP extends into Copilot and third-party AI scenarios to enforce consistent data protection and support compliance. By the end of the session, you will have a clear, practical approach to using DLP to reduce data exposure and securely enable AI adoption.
