Types of VPN kill switches

System level VPN kill switches and application level VPN kill switches are the two different forms of VPN kill switches.

System level VPN kill switch

A system-level VPN kill switch notifies you when the VPN service is terminated. Then, it transmits the data to your device to stop it from using your WIFI or mobile data to access the internet.

When enabled, a system level VPN kill switch entirely disables your computer’s ability to access the internet until the VPN connection is established again or the network adapter is reset. Because of this, it is particularly successful at preventing IP leaks.

Risks of using a VPN without a kill switch

A VPN is a terrific tool for protecting the privacy and security of your online activity. VPNs aren’t perfect, though. Your IP address and sensitive information may get exposed if your VPN connection drops, as we’ve already mentioned.

Therefore, the following factors should be taken into account while choosing a VPN provider:
