A VPN works by routing your device’s internet connection through your chosen VPN’s private server rather than your internet service provider (ISP) so that when your data is transmitted to the internet, it comes from the VPN rather than your computer. The VPN acts as an intermediary of sorts as you connect to the internet, thereby hiding your IP address – the string of numbers your ISP assigns your device – and protecting your identity. Furthermore, if your data is somehow intercepted, it will be unreadable until it reaches its final destination.
A VPN creates a private “tunnel” from your device to the internet and hides your vital data through something that is known as encryption.
The basics of VPN encryption
- When you connect to a VPN, it is through a secure tunnel where your data is encoded. This means that your data is transformed into an unreadable code as it travels between your computer and the server of the VPN.
- Your device is now seen as being on the same local network as your VPN. So your IP address will actually be the IP address of one of your VPN Provider’s servers.
- You may browse the internet as you please, safe in the knowledge that the VPN acts as a barrier, protecting your personal information.
