VPN
A VPN (Virtual Private Network) encrypts all of your device's internet traffic and routes it through a remote server, hiding your IP and protecting data on untrusted networks.
Definition
A VPN (Virtual Private Network) creates an encrypted tunnel between your device and a VPN server. All your traffic flows through that tunnel, so your real IP is masked behind the server's IP and your data is protected from anyone on the local network — useful on public Wi-Fi.
VPN vs proxy
A VPN encrypts all traffic at the operating-system level and prioritizes privacy and security. A proxy typically routes a single app or protocol and is geared toward IP management and scale. For confidentiality use a VPN; for high-volume, IP-diverse automation use proxies.
Examples

Encrypting traffic on public airport Wi-Fi to prevent eavesdropping
