Process exclusions for VMware App Volumes
It is advisable you add the CrowdStrike process exclusions within the VMware App Volumes – Writable Volumes templates on snapvol.cfg. Here is the detailed guidance on how to modify the snapvold.cfg – Using the VMware App Volumes snapvol.cfg File to Customize Writable Volumes | VMware End-User Computing Blog. These two processes are visible within the Task Manager.
#Crowdstrike Exclusions exclude_process_name=CSFalconService.exe exclude_process_name=CSFalconContainer.exe
A big thanks to Jishan for the numerous testing cycles! I hope you will find this script and exclusions useful to install the CrowsStrike Sensor. A small request if you further enhance the script or exclusions, I hope you can share it back with me?
Thanks,
