The Microsoft 365 (M365) integration detects a variety of data loss prevention, account misconfiguration, and user security risks in an integrated Microsoft 365 account that could leave you and your organization vulnerable.
This integration covers the following Microsoft 365 products:
- A Microsoft 365 account with an active Microsoft Business Basic, Microsoft Business Standard, Microsoft 365 E3, Microsoft 365 E5, or Microsoft 365 F3 subscription
- or equivalent permissions in Microsoft 365
For the Microsoft 365 integration to function, Cloudflare CASB requires the following delegated Microsoft Graph API permissions:
