VPNs (Virtual Private Networks) work by creating a secure, encrypted connection between your devices and a VPN server from a service provider (there are dozens of them to choose, from all over the world).Anything you do online - sites you're visiting, emails you send or receive, files you download, web forms you complete - passes through that secure tunnel and can't be intercepted by anyone else (unless one of these servers - or your own computer - is compromised, but that's another story). http://top10vpnsite.com
