Microsoft Defender Licensing Requirements

Senior Member



I have always been under the impression that when licensing Microsoft Defender (Previously ATP) Plan 1 & Plan 2 that you needed a license for each user (You could technically just purchase one license and get all the features but MS advised you need a license per user)


Today MS support explained that the defender licenses are tenant wide (i.e. you only need one license to get defender for you entire tenant) can anyone confirm their understanding of this?


Here is a link to the license terms which in my mind seems to support my original understanding
