An API deployment model with Email security has multiple benefits for Microsoft 365 Customers.

The API deployment with Email security offers:

* Easy protection for complex email architectures, without requiring any change to mail flow operations.
* Agentless deployment for Microsoft 365.
* Office 365 directory integration to retrieve user and group information and prevent user impersonation.
