What must be done to use quarantine on Windows Server 2016 and 2019?

To effectively use quarantine on Windows Server 2016 and 2019, Windows Defender must be manually disabled. This action is necessary because Windows Defender can interfere with other security tools, including CrowdStrike Falcon, when both are active at the same time. If Windows Defender remains enabled, it might counteract the Falcon's quarantine feature by automatically handling threats or files flagged by Falcon, leading to conflicts in how threats are managed.

Additionally, disabling Windows Defender ensures that CrowdStrike Falcon can operate fully and take the necessary actions to quarantine and remediate threats without the possibility of Windows Defender stepping in and overriding those actions. This streamlined approach is crucial for effective endpoint protection and threat management within these specific server environments.
