Web Browser Control

VPNKS Browser Control


In order for this feature to work, VPNKS v1.3 or higher is required and the new VPNKS Browser Control extension for your web browser.

This feature controls your web browser and blocks/unblocks selected webpages when your VPN drops/reconnects to protect your online privacy and internet security.

VPNKS does not only blocks sites BEFORE any data is being sent if your VPN is down, VPNKS is FULLY AUTOMATIC. If it detects a webpage you currently have opened, it will be blocked on the fly. This means that sites that keep transferring data (like ads, logging, tracking, statistics etc) in the background, will be blocked in real-time when your VPN drops. VPNKS will also unblock and refresh all blocked webpages you currently have open when your VPN connection is back up.


  1. Click on "config" in VPNKS and activate the "Web Browser Control":

  2. Install the VPNKS Browser Control extension for your browser:

  3. Click on the VPNKS shield in your browser:

  4. Enter any website into the textfield. Click "Add" to add more websites if needed.
  5. Click "Save" and restart your browser for the changes to take effect.

Setup done!

Temporary Unblock

If VPNKS blocks a site in your setup when your VPN is down, you can still access the webpage by overriding VPNKS and temporary unblocking it. Simply click on the "Unblock" button. This will unblock the webpage for that browser session until you restart your browser again.

Process Protection

With Process Protection enabled, all attempts to run a protected program while your VPN connection is down, will be denied!

Process Protection prevents accidental program-starts and/or other processes from starting up your protected programs while you're still connected to a unsecure internet connection.

Automatic Computer Shutdown

If you want your computer to shut down in case of your VPN shut down, simply check the "shut down" checkbox in VPNKS's main window. If VPNKS detects a VPN connection failure, VPNKS will first terminate all your running programs to make sure all connections are closed and then shut down the computer, no questions asked!
