What is VPN? (2026)
🔍 Quick answer:
A VPN (Virtual Private Network) is a service that creates an encrypted tunnel between your device and the internet. It hides your IP address, protects your data from hackers, and lets you access geo-blocked content.
How a VPN works
When you connect to a VPN, your device establishes a secure connection to a remote server. All your internet traffic is encrypted and routed through this server, so websites see the server's IP address instead of yours.
Why use a VPN
- Public Wi-Fi security: Encrypts your data on coffee shop, airport, and hotel networks.
- Privacy from your ISP: Your internet provider can't see your browsing history.
- Access geo-blocked content: Watch US Netflix, BBC iPlayer, and other region-locked services.
- Bypass censorship: Access blocked websites in restrictive countries.
💡 Pro tip: Always choose a VPN with a no-logs policy and a kill switch for maximum security.
