What Is Kill Switch?
A kill switch is a security feature that automatically disconnects your device from the internet if the VPN connection drops unexpectedly. This prevents your real IP address and unencrypted data from being exposed during connection interruptions.
Why Does Kill Switch Matter?
Without a kill switch, brief VPN disconnections can expose your real IP address and browsing activity. This is especially critical when using public Wi-Fi or accessing sensitive information.
