How Does a VPN Work?

A VPN creates a secure, encrypted connection between your device and the internet. Instead of connecting directly to websites, your data passes through a VPN server first. This hides your real IP address, protects your information from hackers, and lets you browse privately.

• Masks your identity and location.
• Encrypts your internet traffic end-to-end.
• Protects your data on public Wi-Fi networks.

Your IP address identifies your device and location. When you use a VPN, websites only see the IP of the VPN server — not yours. This can make it appear like you’re browsing from another country entirely.

• Prevents advertisers and trackers from profiling you.
• Stops your ISP from logging your browsing history.
• Gives you access to geo-blocked sites and services.

• OpenVPN – Secure and open source, widely used and trusted.
• WireGuard – Lightweight and extremely fast. Used in NordVPN as “NordLynx.”
• IKEv2/IPSec – Great for mobile users; stable with switching networks.
• PPTP/L2TP – Older and faster, but less secure; rarely used today.

• You open your VPN app and select a secure server (e.g., Netherlands).
• Your device and server exchange encryption keys to create a secure tunnel.
• All internet traffic passes through this encrypted tunnel safely.
• Websites only see the VPN’s IP address — not yours.
