I'm in the process of rolling out Defender for Servers via Defender for Cloud subscription to onboarded ARC on-prem machines (Windows and Linux). The current solution uses a lot of file and folder exceptions. I've rolled out to a few test machines but i do not see anywhere to add any exceptions for these onboard machines.
I have found some MS instructions but they are not accurate - at least, I don't see the sections in the Cloud Portal that the instructions say I should see.
Is the only option for exceptions (we don't use Intune), GPOs in combination with the MDE sensor that is pushed to onboarded systems?
My concern is installing MDE via Defender for Cloud onboarding where an existing installation of McAfee is running which might impact performance. The instructions online to provide commands to confirm MDE is in passive mode (because there's already a scanning running) but those PS commands either do not work and error out or do not provide outage as described in the instructions.
Any assistance would be helpful!
Hello,
It's possible you've already found a solution to move ahead. But incase you're still looking for assistance, I wanted to leave you with these steps:
Yes you should absolutely ensure not to disturb the workloads by having McAfee and Defender fight for resources. This is also highlited in Red Here https://learn.microsoft.com/en-us/defender-endpoint/microsoft-defender-endpoint-linux
If you're still getting started off, can you attempt a manual installation using steps here https://learn.microsoft.com/en-us/defender-endpoint/microsoft-defender-endpoint-linux#installation-instructions?
Our guidance for running in passive mode is here https://learn.microsoft.com/en-us/defender-endpoint/linux-preferences#enforcement-level-for-antivirus-engine (for Linux).
And for Exclusions is here https://learn.microsoft.com/en-us/defender-endpoint/linux-preferences#type-of-exclusion
Finally, worth scanning thru this lessons-learned FAQ before getting started.
