Why it matters
Microsoft Copilot's inheritance of user permissions means AI assistants can surface overshared or stale sensitive data that DLP and sensitivity labels fail to contain, a governance risk defenders must address before broad AI adoption.
An NHIMG editorial, based on content published by Sentra, frames the Microsoft Copilot Chat exposure as a data-posture problem rather than an AI control failure: Copilot inherits user permissions and can summarize years of overshared Microsoft 365 content because it operates on access reality, not policy intent. The piece argues DSPM, classification accuracy, and access cleanup are prerequisites for secure AI adoption and offers practitioner guidance on inventorying AI-reachable content and reconciling sensitivity labels against actual exposure.
