If you’re unfamiliar with VPN services, the value behind a VPN is this: You encrypt all data from your local computer to the VPN endpoint, adding security to an otherwise insecure situation. A prime example is when you use an unsecured wireless connection (for example, at a cafe or a university) or when your government wants to control or spy on your internet activity (Egypt and China come to mind, but many examples exist world-wide).
Two software products worth mentioning that aren’t strictly services but received a lot of attention in the voting include: OpenVPN is a client which can connect to any VPN service and is a component of popular “roll your own” setups. If you have the technical know-how, you can set up your own PPTP or IPSec service out of your own home or business. Also LogMeIn Hamachi is a free tool and service for creating a point-to-point VPN network between computers. You could use Hamachi to share your internet connection on your home PC with a remote computer and have a very nice and secure connection.
