What is a VPN?
Understanding Virtual Private Networks and how they protect your online privacy
Basic Concept
A Virtual Private Network (VPN) is a service that creates an encrypted tunnel between your device and the internet. When you use a VPN, your internet traffic is routed through this secure tunnel, making it virtually impossible for anyone to intercept or view your online activities.
How Does a VPN Work?
- You connect to a VPN server through an encrypted connection
- Your internet traffic is routed through this secure tunnel
- Your IP address is masked with the VPN server's address
- Your data remains private and secure from prying eyes
