Most companies I’ve worked at where employees had a Microsoft work computers. They were under heavy control, even with admin privileges. I was wondering, for a corporate environment, how employees’Linux desktops could be kept under control in a similar way. What would be an open source or Linux based alternative to the following:

• policy control
• Software Center with software allow lists
• controlled OS updates
• zscaler
• software detection tool to detect what’s been installed and determine if any unallowed software is present
• antivirus
• VPN

I can think of a few things, like a company having it’s own software repos, or using an atomic distribution. There’s already open source VPN solutions if course. But for everything else I don’t really know what could be used or what setup we could have.
