How does a VPN work?
The short version: Accessing the internet with a VPN is like putting a package into a box and sending it to someone. Nobody can see what’s inside the box until it’s opened, or in this case, decrypted.
A VPN creates an encrypted “tunnel” over the internet to protect the data traveling between you and your Internet destination — anything from your online banking account to a video sharing website to a search engine.
This tunnel is created by first authenticating your client — a computer, smartphone or tablet — with a VPN server. The server then uses one of several encryption protocols to make sure that no one can monitor the information traveling between you and your online destination.
