How does a VPN kill switch work?
When enabled, your VPN kill switch constantly monitors your VPN connection and checks for changes in your IP address or the state of your network. The kill switch will immediately block internet access when it detects a change in the state of either. When you reconnect to the VPN server or the VPN tunnel automatically re-establishes itself, the kill switch will allow the Internet to reconnect and will continue to monitor your VPN connection.
There are two different types of VPN kill switches: one that works at the application level and one that works at the system level.
An app-level VPN kill switch allows you to choose specific apps on your device to stop if the VPN connection drops. While certain apps will be blocked, any other apps that are connected and that you haven’t selected to kill will remain connected and may put you at risk. An application-level kill switch gives you a certain amount of flexibility, but you need to be mindful of which applications you do or don’t choose to include. A system-level kill switch is generally a safer option because it kills all network traffic on your device at the system level when it detects a failed VPN tunnel.
Some VPNs such as NordVPN Offers both an application-level and system-level kill switch, others like it ExpressVPN Offer only a system-wide kill switch. ExpressVPN’s Network lock The kill switch is enabled automatically, but it is not enabled by default in all VPNs that have the kill switch. If the VPN kill switch is not enabled by default, you can go to the settings section of your VPN client and activate it there.

To test your VPN kill switch, you will first need to make sure that your normal internet connection is working properly. Once you are sure that your internet is working, connect to your VPN and enable the kill switch if it is not already enabled. After that, you can either disconnect from the VPN server or simulate a VPN failure by doing something like manually killing and then re-establishing the network connection, closing and then reopening your laptop, or activating and then deactivating Airplane mode on your mobile device. If you notice that you have lost access to the Internet or the applications you reported are closed with the kill switch at the application level, then the kill switch is working properly.
Alternatively, you can use an auto-updating website like update page And add the following in the appropriate field: http://ip-api.com/csv
Next, set the page refresh time to 1 second. With your VPN disconnected, click Start and make a note of the normal IP address that displays in the new window that pops up. Next, connect to your VPN (preferably to a server in another country) and click Start again. You should see the IP address and location of the VPN server that you are connecting through. Now, simulate a VPN connection being disconnected and pay attention to what happens in the page activation window.
