About Virtual Private Networks
Understanding the fundamentals of VPN technology, its history, and how it protects your digital privacy.
What is a VPN?
A Virtual Private Network (VPN) is a technology that creates a secure, encrypted connection between your device and a remote server. This encrypted tunnel protects your internet traffic from prying eyes and allows you to browse the web privately and securely.
When you connect to a VPN, your internet traffic is routed through an encrypted tunnel to a VPN server, which then forwards your requests to the internet. This process masks your real IP address and location, making it appear as if you're browsing from the VPN server's location.
How VPNs Work
Connection Initiation
Your device connects to a VPN server using a specific protocol (OpenVPN, WireGuard, IPsec, etc.).
Authentication
Your device authenticates with the VPN server using certificates, pre-shared keys, or username/password.
Encryption
All data transmitted between your device and the VPN server is encrypted using strong cryptographic algorithms.
Traffic Routing
Your internet traffic is routed through the encrypted tunnel to the VPN server, which forwards it to its destination.
