Your concerns are understandable, especially given the sensitivity of enterprise data.

However, with proper governance, Copilot is designed to operate securely without compromising data, IP, or competitive edges.

When correctly configured, Copilot accesses only the Microsoft 365 data (docs, emails, etc.) a user is explicitly authorized to view via the Microsoft Graph, respecting existing permissions.

Data stays within the organization’s tenant, encrypted at rest and in transit, and isn’t used to train Microsoft’s models or shared externally. Prompts and responses are processed in-memory, and admins can audit interactions via Microsoft Purview without Microsoft accessing the data.

With robust controls such as strict access policies, regular audits, limited data scope, and third-party plugin vetting, Copilot doesn’t index or expose sensitive data beyond what’s permitted.

For example, sensitive documents or emails remain inaccessible to unauthorized users, and web queries are anonymized, adhering to enterprise-grade protections like GDPR.

While misconfigurations could pose risks, proper governance mitigates these, allowing businesses to leverage Copilot’s efficiency benefits securely.

It’s critical to enforce these controls and train employees to use it correctly to avoid internal leaks or oversights.
