A VPN works by encrypting your online presence. The only way to decipher this encryption is with a key. Only your computer and the VPN know this key, making it impossible for your ISP to tell where you are browsing.

Different VPNs will use different encryption processes, but generally speaking, it works in three stages:

  1. Once online, you boot up your VPN. The VPN acts as a secure tunnel between you and the internet – your ISP and other third-parties won’t be able to see into this tunnel.
  2. Your device will now be on the VPN’s local network, and your IP address can be changed to one of the IP addresses provided by the VPN’s servers.
  3. You can now browse the internet as you please, as the VPN protects your personal data.
