Eyes are everywhere online.

The websites you visit often track where you came from and watch where you head off to next.

A VPN – or virtual private network – helps you browse the internet more anonymously by routing your traffic through a server that is not your point of origin.

It is a bit like switching cars to shake off someone who is tailing you.

There are plenty of companies offering services with varying degrees of security and varying degrees of cost, but if you are willing to roll your sleeves up and get technical with some basic coding and a £30 Raspberry Pi computer, you can build your own VPN server at home.

You can then connect external devices like a smartphone to this VPN tunnel to browse the internet more securely through your home network, and access shared files and media on your home computer.

Make no mistake, this is not a quick and easy process.
