What is VPN? How Does It Work?

In today’s digital age, protecting your online privacy and ensuring data security is more important than ever. That’s where VPN (Virtual Private Network) technology comes into play — a secure, encrypted tunnel between your device and the internet.

What is a VPN?

A VPN masks your real IP address and encrypts your internet traffic, routing it through a secure server. This makes you anonymous online and helps bypass geo-restrictions or content censorship.

What Can You Do with a VPN?

Browse the internet anonymously

Hide your real IP and change your virtual location

Protect your data on public Wi-Fi networks

Access restricted or blocked websites

Encrypt your traffic to avoid third-party interception

Prevent tracking and profiling

How Does a VPN Work?

1. You connect to a VPN service

2. Your IP address is replaced by one from the VPN server

3. Your internet traffic is encrypted and rerouted

4. The destination site sees only the VPN’s IP, not yours

5. Your identity and activity remain hidden and secure
