A Virtual Private Network (VPN) creates an encrypted tunnel between your device and the internet. In 2025, over 32% of U.S. adults use a VPN daily for privacy and security — and you can too, with just one tap.
If you’re new to VPNs and use apps on your PC, Mac, iPhone, Android, or browser, this guide explains everything in plain English — no jargon, no complexity.
How a VPN Works (Step-by-Step in 2025)
Here’s what happens when you tap “Connect” in a modern VPN app:
- Your device connects to a VPN server (e.g., in New York or London).
- All your traffic is encrypted with AES-256 — military-grade protection.
- The server forwards your request to the website (e.g., Netflix, Gmail).
- The response comes back through the same encrypted tunnel.
- You see the site normally — but your real IP and activity are hidden.
Two Main Ways People Use VPNs Today
1. Personal VPN (What 99% of Users Do)
You install an app, pick a server, and go. Perfect for:
-
- Public WiFi at cafés, airports, hotels
- Streaming shows from other countries
- Keeping your ISP from logging your history

2. Site-to-Site VPN (Business Use)
Connects entire offices securely. Uses dedicated hardware. You don’t need this as a beginner.
