Microsoft Copilot Security: Fix Data Leaks & Over-Sharing

Microsoft Copilot Security: Fix Data Leaks & Over-Sharing is explained in this M365 FM video guide. Learn the core concepts, key capabilities, practical use cases and implementation considerations for real-world Microsoft environments.

Most leaders think governance controls AI, but policies do not make decisions at 4 p.m. when a model drifts or a co-pilot surfaces sensitive data, people do. This session moves beyond passive policy to active stewardship, ensuring your organization has the stopping power to handle AI behavior before it becomes a disaster. We explore why traditional governance fails upon contact with reality and how to build a distributed decision engine that actually works.

Throughout this deep dive, we utilize Microsoft's reference architecture, including Entra, Purview, and Copilot, to show how identity and data boundaries encode your intent. You will walk away with a first draft stewardship RACI, a 90-day implementation plan, and a use case inventory structure that scales with your organization. We cover everything from defining non-delegable decision rights to building escalation workflows that resolve incidents in minutes rather than weeks.

Whether you are a CAIO, an IT leader, or a product owner, this video provides a role-specific playbook to ensure your AI systems remain safe, explainable, and compliant. Learn to identify failure patterns like shadow AI and governance theater while establishing a culture where stopping revenue for safety is a boring, rehearsed procedure rather than a heroic act.
