A VPN protects your privacy by encrypting your internet traffic. However, if your VPN connection suddenly drops, your real IP address can be exposed.
This is where a VPN kill switch becomes important.
What Is a VPN Kill Switch?
A VPN kill switch is a security feature that automatically blocks your internet connection if the VPN disconnects.
This prevents:
IP address leaks
Data exposure
Unprotected browsing
