What are VPNs and do you need one?

A VPN or Virtual Private Network, is a secure connection to another network over the internet. This may allow you to circumvent region restrictions on services, keep your data safe while using public Wi-Fi, and give you some degree of online anonymity.

Many people use such services in an attempt to be able to watch, for example, a different region’s Netflix or other streaming service. Doing that is a legal grey area.
