There’s a good chance you’ve heard about virtual private networks, or VPNs, but have no idea what they are. VPNs are, in essence, a way of establishing a secure and direct connection — like one you might have between two computers in the same office.
Using fancy techniques like dedicated connections, virtual tunneling protocols and encryption, a VPN distributes a connection that runs according to the same security and operational rules as that direct connection, only it’s distributed through a public network — namely, the internet.
