Is Microsoft Entra ID P1 (formerly Azure Active Directory P1) Required to use SaaS Alerts?

Microsoft Entra ID P1 Licensing for your customer is recommended but it's not required to use SaaS Alerts. Microsoft provides additional information via APIs for tenant Organizations that have a Microsoft Entra ID P1, and SaaS Alerts has developed some features to take advantage of that information. SaaS Alerts was specifically developed with the Business Basic / Free Azure Ad tenant in mind. 

A P1 license is required to allow for data gathering for our MFA report and to view SSPR information as well.

 

Be aware that while one P1 per tenant may work, Microsoft's policy is that every user must have a P1.
