VPN stands for virtual private network, and there are several reasons why you might want to use one.

It does the same thing when you’re using the internet at home, or in the office.
A VPN can also be used to make it appear as if you are located in another country. This can unlock services that are blocked from your real location, for example, you can watch catch-up TV like BBC iPlayer while on holiday or a business trip abroad.
