Microsoft Defender Suite
Also known as Microsoft 365 E5 Security
Microsoft's bundled security add-on: Entra ID P2, Defender for Endpoint P2, Defender for Office P2, Defender for Identity, and Defender for Cloud Apps.
Formerly sold as the Microsoft 365 E5 Security add-on, it was renamed to Defender Suite and can now sit on top of Business Premium rather than requiring an Enterprise base plan.
Bought as a bundle it costs materially less than the five components purchased individually, so it is almost always the cheaper route once you want three or more of them.
Where this comes up
Microsoft Defender Suite sits inside our microsoft 365 and cloud work. If you are trying to work out what this means for your own environment rather than in the abstract, that is the page worth reading next, and a short call will get you a straight answer faster than either.
