- Performance issues have been observed on RHEL servers after installing Microsoft Defender ATP. These issues include:
- degraded application performance, notably with other third-party applications (PeopleSoft, Informatica, Splunk, etc.)
- lengthy delays when SSH'ing into the RHEL server.
- Under Microsoft's direction, exclusion rules of operating system-specific and application-specific files, folders, and processes were added. That has helped, but not eliminated the problem.
- One has followed Microsoft's guidance on configuration and troubleshooting.
