VPNs (Virtual Private Networks) can be used for several things. The most common use of them is to bypass geographical restrictions. There are many sites and services on the net that only serve certain regions; Netflix, for example, is only available in the US, Canada and some Latin American countries. Using a VPN server that is located within the allowed regions will give you access to that particular service. There are also other uses such as providing anonymity, higher privacy and a more secure connection. There are several “free” services out there but they always come with some kind of special condition. VPN Gate, however, is a truly free service.
