Thank you for posting in our online help forum! We don't currently have an internal or external document of compatible VPNs.
The general rule is that most VPNs are compatible with our monitoring software, Screen Accountability44, on Mac® and Windows computers.
However, our filtering service41 (which blocks explicit websites) is NOT compatible with VPNs. So you cannot use our filter and a VPN on a device/router together.
Let me know if you have any other questions,
