What is VPN?

Also known as: virtual private network

Definition

A VPN (virtual private network) creates an encrypted tunnel between your device and a VPN server, hiding your traffic from the local network and internet provider.

Why it matters

It is useful on untrusted Wi-Fi and for reaching business systems remotely. It does not make you anonymous or protect you from phishing and malware, and the VPN provider can see your traffic metadata.
