r/sysadmin on Reddit: License(s) required for Microsoft Defender
August 20, 2024 -

We would like to examine what licenses are needed for Microsoft Defender. We currently use third-party solutions for anti-malware, web content filtering, and vulnerability management. Users with computers normally have O365 E3 and EMS E3 licenses, while users without a PC are given an Exchange P1 and EMS E3 license. What licenses and/or add-ons would be needed to move these services to the Microsoft equivalent? I am hoping the answer is not MS365 E5 because that is cost-prohibitive.

Thank you!
