• Ideal for quick privacy protection on Chrome, Firefox, Brave and other browsers.

• Works independently from your operating system.

What Exactly Is a VPN Extension?

A VPN extension is an add-on you install in your browser (like Chrome or Firefox) that secures your browsing traffic. Unlike full VPN apps that protect every connection on your device, extensions focus specifically on the activity happening inside the browser window.

They are popular because they’re simple to activate - usually with just one click.

How Does a VPN Extension Work?

1. It encrypts browser traffic

A VPN extension uses secure tunneling protocols to encrypt data so that anyone monitoring your network (like Wi-Fi providers) can’t see what you’re doing online.

2. It connects you to a secure remote server

Your browsing traffic is routed through a trusted VPN server operated by the provider.

3. It hides your real IP inside the browser

While your operating system continues to use your local internet connection normally, your browser traffic is routed through the VPN server.

4. It works instantly without system-level permissions

Because it runs only in the browser, installation and operation are extremely lightweight.

Is a VPN Extension Enough?

A VPN extension protects browsing activity, but anything outside the browser (apps, email clients, software updates) stays unprotected.

For full-device protection, a standalone VPN app is needed.
