Why a Kill Switch feature is important to VPN?

A kill switch feature is important to a VPN when you lose your internet connection and thus your VPN server encryption.

Your laptop, smartphone, or another device will most likely revert to the public IP address provided by your home ISP.

This means that your online activity and browsing history, as well as your IP address and location, may become visible to and tracked by others at any time.

A VPN kill switch feature adds security by preventing DNS leaks and Wi-Fi packet loss.
