Use the Mimecast and Microsoft Azure AD integration to securely access the Mimecast Administration Console. While Mimecast will secure your email gateway, this integration will protect users when logging into any single sign-on applications including the Mimecast portal. Any users posing a potential threat will be locked out of their account wile necessary security measures are taken to assess the origin of the threat. Customers can ensure that threatening users or domains will not be able to access the Mimecast portal again until the threat is resolved.

Microsoft Azure AD and Okta SSO are also very similar and have almost the same key capabilities. 

Mimecast + Microsoft SSO Use Cases:

• User Lockout: Control access to sensitive applications for compromised users.

• Prevent Logon: Prevent users from accessing sensitive applications.
