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.

Last updated May 28, 2026

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

1

Connecting to a VPN server in another country to access geo-restricted streaming

2

Encrypting traffic on public airport Wi-Fi to prevent eavesdropping

Common Use Cases

Securing traffic on public Wi-Fi
Hiding your IP address for privacy
Accessing geo-restricted content
Bypassing local network censorship

Frequently Asked Questions

A VPN encrypts all device traffic for privacy and security, while a proxy usually routes a single app or protocol and is optimized for IP management and scale.
No. A VPN hides your IP and encrypts traffic, but browser fingerprinting, logged-in accounts and provider logging can still identify you.
