VPN kill switch feature
VPN software come with lots of different features. On this page we will zoom into the kill switch feature. The kill switch feature is a feature that prevents your device from making unprotected connections. It monitors your connection to the remote VPN server. If the connection accidentally drops, the kill switch will block your internet access, or even your local network access. When the connection with the VPN server is restored the traffic can resume.
First check if your VPN vendor supports your operating system and check which methods you can use. For the latest information visit the websites of the vendors. Here is an overview based on September 2021:
Some VPN vendors support VPN services on your home router. Because this is so specific you should check out the site of the vendors for more information. In general you need a router where you can setup a VPN tunnel.
Most of the time the kill switch feature is not enabled by default, so if you want to use it, you have to manually enable it. In general you have two types of kill switch methods:
- System wide
- Application/website specific
Application and website specific kill switch methods
With this method you can block specific applications or website, but all the other applications will still work when the VPN connection with the VPN server is lost.
There are some other features which can be used in conjunction with the kill switch method. The first one is automatic connect and the second is Split tunnel.
Automatic connect is another feature that lets you connect automatically. This works beautifully in conjunction with the kill switch. This enables you to automatically connect, even if you switch between networks and you don’t have to do any manual connecting every time. In general you can select the following automatic connect options:
- Only on cellular networks
- Only on Wi-Fi networks and ethernet
