Kill Switch
A kill switch automatically cuts your internet connection if your VPN drops, preventing your real IP and traffic from being exposed.
Definition
A kill switch is a VPN safety feature that instantly blocks all internet traffic if the encrypted VPN connection unexpectedly drops. Without it, your device would silently fall back to your normal connection, exposing your real IP and unencrypted traffic.
Why it matters
VPN connections can drop momentarily when switching networks or servers. A kill switch ensures that during those gaps nothing leaks — essential for anyone relying on a VPN for privacy or for tasks that must never reveal the real IP.
Examples
Your connection freezing for a moment when the VPN reconnects, instead of leaking
An app-level kill switch that only blocks specific programs
