Copilot Governance: Microsoft's AI Assistant Sparks Security Concerns

Microsoft's AI-powered Copilot is revolutionizing the Windows experience, but it also poses significant governance challenges for IT leaders. As users interact with data in new ways, existing policy frameworks struggle to keep up.

Copilot uses large language models combined with organizational data to help users draft content, summarize information, and answer questions directly within apps like Word, Excel, and Teams. It operates through Copilot Chat, a cross-application interface where users can query information across their entire Microsoft 365 data estate.

However, this new level of interaction raises concerns about data governance, particularly around oversharing and latent security risks. IT teams must account for the risk surface on every managed endpoint expanding significantly as AI assistants surface documents, summarize emails, and trigger autonomous agents through Copilot Studio and even locally on the user's device.

Microsoft provides some built-in guardrails and capabilities to help control these GenAI features, but many of these mechanisms are not enabled by default. IT teams must evaluate governance risks around latent oversharing, identity sprawl from agents, data residency and model variation, and local execution surface.
