VPN Extension

What Is a VPN Extension?

A VPN extension is a browser plug-in or add-on that encrypts your online activities and personal data when using a browser.


To fully understand a VPN extension, however, you must first be familiar with a VPN. A virtual private network, or VPN, is an external network you use to connect to the internet. It acts as a shield to protect your online data and keep your online activity secure so your digital identity is not publicly available. A VPN is available as either an app or a browser extension. 

How Does a VPN Extension Work?

Just like a regular VPN, the VPN extension also encrypts your internet connection and reroutes it through an offshore VPN server. However, unlike the typical VPN that protects all your online activities, the VPN browser extension encrypts activities only for the specific browser where it is installed.

Once you install the extension on your preferred browser and activate it, the browser extension will begin to act as an intermediary between your computer and the sites you visit. It reroutes your internet traffic through a remote server, encrypting your internet activities and personal data, making it hard for even your internet service provider to track.
