Toronto businesses rolling out Microsoft 365 Copilot need to understand one thing before they start: Copilot surfaces data based on what the user has permission to access. If your Microsoft 365 permissions are too broad — and most GTA businesses we assess have over-permissioned environments — Copilot can surface sensitive files to users who should not see them.

Before enabling Copilot, it is essential to audit SharePoint and OneDrive permissions, remove legacy broad-access grants, and ensure that sensitive client files are in properly secured document libraries with appropriate access controls.

Group 4 Networks prepares Microsoft 365 environments for Copilot deployment — securing your data before AI can access it.
