Overview
In case the VPN unexpectedly disconnects, Kill-Switch stops your device from accessing the internet. As soon as you are re-connected to the VPN server location, your internet traffic will be restored automatically.
This adds an additional layer of security to the VPN, by preventing any unwanted (private) information from leaking across your regular (public) network without your knowledge or permission.
Windows
This setting is only recommended for advanced VPN users. In most cases, you do not need to adjust this option. However if you have a poor or unstable internet connection, Kill-Switch can help by blocking any unencrypted traffic before it reaches the other end.
This feature is entirely optional, and it can be enabled or disabled at any time.

Common Questions
Why can't I find the Kill-Switch option on my device?
It is possible you have an older/legacy version of our app installed on your device. We recommend installing the latest version of the app in order to be fully protected against the latest threats.
Why would the VPN unexpectedly disconnect in the first place?
This can happen for a number of reasons, including a poor/unstable connection, when your network changes, or when your device enters Sleep/Hibernation mode.
