By asking about conflicts with an existing VPN, are you trying to run two VPNs at once? I ask because that's usually tricky to accomplish. I have two that reside on my devices and just use the one for whatever I need to do (work tasks or home stuff).

I've been extremely satisfied with Private Internet Access. Used them for years now.

I would think it would be an either or kind of thing so compatibility shouldn’t be a problem as long as you don’t try to run both at once. I don’t know why anyone would want to. It sounds like scouter is required to use a VPN on his own device at work but want’s one of his/her own to use when not on the company network. I don’t think having two installed on one device would be a problem.
