At its core, a Virtual Private Network (VPN) creates a private, encrypted tunnel between your device and the internet. Think of it as a secure armored car for your data traveling on a public highway.

How a VPN Works

When you connect to a VPN service, your data is encapsulated in an encrypted 'envelope' before it even leaves your device. It then travels to the VPN server, where it is decrypted and sent to its final destination with a different IP address.

Expert Tip
Always use modern protocols like WireGuard or NordLynx for the best balance of battery life and security.

The Benefits of using a VPN

  • Hide your IP address from websites and trackers
  • Encrypt your internet traffic on public Wi-Fi
  • Access content that is blocked in your current location
  • Prevent ISP throttling of streaming services
Privacy Warning
Free VPNs often sell your data to third parties to cover their costs. If you aren't paying for the product, you are the product.
