Appendix G: Permitted IP Addresses to access the Avanan Azure Application

When activating protection for Office 365, Avanan installs the Avanan Cloud Security Platform—Emails V2 Azure application in your Microsoft 365 environment.

Avanan uses API calls directed to the Avanan Cloud Security Platform—Emails V2 application to quarantine or restore emails, block users, and perform other actions.

Avanan sends API calls to this application from a specific set of IP networks.

Note - The administrator must treat access attempts from any other IP addresses as unauthorized and potentially originating from threat actors.
