Milad Aslaner hope you are fine and can still help on this old thread. Since 2018 many things have apparently changed to the better.
many questions still arise for newbs in to this topic
2020 Ignite
- announced Azure Security Center - is this merging the capability to manage Windows Server and Client at a single dashboard
- Why there is still a need for Microsoft 365 Defender dashboard in M365 admin center
- Now as I understood Server could be licensed with M365 prerequisites to a standalone ATP license it is not described in the docs how to do this.
- your tables from 2018 already stated that on-premises Windows server LTSC 2016 / 2019 do not need any agent to work with Azure Security Center
Windows Defender Antivirus is built-in and requires no agent installation"
yet the docs still talk about you need to install a MMA Monitoring agent even in Option 2, so we apparently still need to install something.
