A virtual private network (VPN) is a network that connects a remote
PC — your laptop beside the pool in Shanghai — to a central network
elsewhere, like your employer's secure network back home.
Think of VPNs
as tunnels; secure tunnels that your sensitive data can travel through
on its way to its destination.
The purpose of a VPN is to allow you to access your data from
anywhere without any sacrifice of security. With a VPN connection,
everything seems as though you are simply connected directly to your
network, regardless of where in the world you might actually be.
Running over a Wi-Fi network, a well-secured VPN session will
appear as a standard https connection to anyone watching the packets as
they come and go. That means it will defeat most surveillance,
interception and data theft.
Sounds good, right? Here's our guide to setting up your own VPN for secure connections wherever you go.
