VPN protects your privacy by creating a secure tunnel across the Internet between you and your Internet destination. This tunnel is created by first authenticating your device (a PC, tablet, or smartphone) with a VPN server. The server, which you can run yourself with programs such as OpenVPN, then uses one of several encryption protocols to make sure that everything sent between you and websites and Internet services can't be monitored. It does this by creating an encrypted tunnel, which is like putting a package into a box and then sending it to someone. Nobody can see what it's inside the box until it's opened or decrypted. |
