New version of Windows EDR sensor released to production Feb 8th 2022 (version 2022.1.19), which will introduce enhanced self-protection features, results removal of 'fsatps.exe' process. Therefore any existing controls witch rely on the presence of this 'fsatps.exe' process will become in-effective once this update is released.
Our recommendation is to utilise the 'fsulprothoster.exe' for these types of use cases instead.
