Kill Switch Protection
Understand how VPN kill switches work, why they're essential for privacy, and when you need one.
What is a Kill Switch?
A VPN kill switch is a safety feature that monitors your VPN connection and automatically blocks all internet traffic if the VPN disconnects unexpectedly. Without a kill switch, your device would continue sending data over your regular internet connection if the VPN drops, exposing your real IP address and unencrypted traffic to your ISP and anyone monitoring the network.
How Kill Switches Work
Kill switches work at the system level, monitoring your VPN connection status constantly. If the connection fails,whether from network interruption, VPN server issues, or switching WiFi networks,the kill switch instantly blocks all traffic from leaving your device. Once the VPN connection is restored, internet access resumes automatically. This happens in milliseconds, preventing any data leakage.
Types of Kill Switches
There are two main types of kill switches. Active kill switches continuously monitor the VPN connection and react immediately to disconnections. Passive kill switches use firewall rules that only allow traffic through the VPN interface. Both approaches achieve the same goal: ensuring your traffic never leaks outside the VPN tunnel.

Common Myths Debunked
Kill switches slow down your internet connection
Kill switches add no measurable performance overhead. They simply monitor connection status and don't affect data transfer speed when the VPN is working normally.
I don't need a kill switch if I have a reliable VPN
Even the most reliable VPNs can experience momentary disconnections due to network changes, server issues, or switching from WiFi to mobile data. A kill switch provides essential protection during these brief interruptions.
Kill switches will lock me out of my device
You can always disable a kill switch or VPN app if needed. Kill switches only block internet traffic,you retain full control of your device and can turn off the VPN at any time.
