TunnelBear claims to be secure but all they offer is an opaque app. Uhh, no thanks. I prefer to run my own VPN client that doesn't have potential spyware in it. I am surprised this was so highly rated by someone reviewing VPNs.
edit: I know you can't make everyone happy, but there are a LOT of VPN options out there and only the very best should be making it through.
That is nice of them to release a sanitized version of the audit report. I would still prefer openvpn or some other open source client that has been more battle tested for something I intend to use as a privacy tool. I don't think it changes my basic position on a closed source client. Audits are always point in time.
