What is VPN?

A VPN (Virtual Private Network) encrypts your internet traffic and routes it through a remote server, hiding activity from the local network and your ISP, and letting you appear to browse from another location.

Use one on public Wi-Fi, for privacy from your ISP, or region-locked content. Reputable paid services (or your workplace's VPN) are the way in — "free" VPNs typically pay for themselves with your data.
