You can see if the launchd service is still installed for it:
sudo launchctl list com.checkpoint.epc.service
You can unload it if is loaded:
sudo launchctl unload /Library/LaunchDaemons/com.checkpoint.epc.service.plist
If you need to remove the service startup script manually, it's there in "/Library/LaunchDaemons/com.checkpoint.epc.service.plist".
This is the Mac's version of the Linux systemd (or SysV init) scripts. Keep in mind, tho, that by default, a lot of these system folders are hidden by default on macOS, so a lot of the times a cursory scan won't show anything. You'll have to navigate directly using the Finder's "Go to Folder" option:
If none of this helps, then you just might need to open a TAC case to figure out what's still embedded.
