What is a VPN?
A Virtual Private Network (VPN) is a security tool that creates an encrypted connection between your device and the internet. Think of it as a secure tunnel that protects your data from prying eyes while you browse, stream, or work online.
How Does a VPN Work?
When you connect to a VPN, your internet traffic is routed through an encrypted tunnel to a remote server operated by the VPN service. This process:
- Encrypts your data - Makes it unreadable to hackers, ISPs, and government agencies
- Masks your IP address - Replaces your real IP with the VPN server's IP (check your current IP on our homepage)
- Changes your location - Makes it appear as if you're browsing from the VPN server's location
- Protects your privacy - Prevents websites from tracking your real location and identity
VPN Encryption Explained
VPNs use military-grade encryption protocols (like AES-256) to scramble your data. Even if someone intercepts your connection, they'll only see gibberish instead of your actual browsing activity, passwords, or personal information.
Common VPN Protocols:
- OpenVPN - Industry standard, highly secure and open-source
- WireGuard - Modern, fast, and efficient protocol
- IKEv2/IPSec - Great for mobile devices, quick reconnection
- L2TP/IPSec - Older but still widely supported
What Can You Do With a VPN?
✅ VPN Benefits

VPN vs Proxy: What's the Difference?
While both mask your IP address, a VPN provides full encryption of all your internet traffic, while a proxy only reroutes traffic from specific apps without encryption. Learn more about different methods to change your IP address.
