Sensitivity labels look simple in demos. In production, they're anything but. This session goes well beyond the basics of Microsoft Purview sensitivity labels into how they actually behave across cloud repositories, workstations, and on-prem file shares. We'll break down encryption models, the difference between user-defined and admin-defined permissions, permission templates, and how label policies are evaluated when multiple conditions compete for the same content. More importantly, this session is about what goes wrong and how to get ahead of it. Real-world failures where labels blocked collaboration, encryption broke business processes, and organizations lost access to their own data because the person who encrypted it left and no one planned for that. We'll look at which permissions to assign, which to hold back, and how small scoping mistakes cascade at scale.
We'll also dig into the role of custom sensitive information types and trainable classifiers in auto-labeling, why out-of-the-box classifiers fall short, and the gotchas that cause auto-labeling to either do nothing or encrypt far more than intended. Labeling and classification are the foundation for everything in data security, from DLP to Insider Risk to controlling what Microsoft 365 Copilot can access. If your labels aren't right, nothing downstream works properly. We'll cover how to keep Copilot from surfacing labeled content it shouldn't reach, and why getting this layer right is more urgent than ever. Expect detailed configuration walkthroughs, real production scenarios, and technical depth you won't find in the documentation.
