Seems like the most popular one is Tunnelbear. To be honest, from that list I have already used two: PIA (Private Internet Access) and PureVPN and have nothing against. Stopped using PIA some time ago because there I didn't really trusted their support responses regarding how the logs were being kept or saved.
I have been using PureVPN so far and nothing to complain about.
You seems little bit Sounds with the IT knowledge. Please be sure that you should dig up the old topic which is been already answered and op satisfied about his query. By the way you can should not dig it unwantedly. To be go with official VPN client contact you can use Cisco client to that.
