Secure Shell (SSH): SSH creates both the VPN tunnel and the encryption that protects it. This allows users to transfer information unsecured data by routing the traffic from remote fileservers through an encrypted channel. The data itself isn't encrypted but the channel its moving through is. SSH connections are created by the SSH client, which forwards traffic from a local port one on the remote server. All data between the two ends of the tunnel flow through these specified ports. But for a company that bills itself as "the world's fastest VPN," was kind of mediocre, with our download speeds dropping to a third of the non-VPN baseline. Free users are limited to 2GB of monthly data and can connect to servers in only three countries; either of those limitations would be more acceptable if the network speeds were faster.
