What is a VPN – A VPN (Virtual Private Network) is a service that creates a secure, encrypted connection between your device and the internet. It hides your real IP address and routes your traffic through a remote server, protecting your privacy and data.
How a VPN Works
- You connect to a VPN app or router.
- Your device establishes an encrypted tunnel to one of the VPN provider’s servers.
- All your internet traffic passes through this tunnel.
- The VPN server forwards your requests to websites and returns the responses.
- Websites see the VPN server’s IP address instead of yours.
This encryption prevents your ISP, hackers on public Wi-Fi, and other third parties from seeing your activity.
Types of VPNs
- Consumer VPNs — Designed for individuals (e.g., streaming, privacy, torrenting).
- Business / Enterprise VPNs — Used by companies to let remote employees securely access internal networks.
- Self-hosted VPNs — Run on your own server (e.g., using OpenVPN or WireGuard).
Benefits and Uses
- Protects privacy by hiding your IP address and encrypting data.
