VPN Kill Switch

Your last line of defense. Automatically blocks internet traffic if your VPN connection drops unexpectedly.

What is a Kill Switch?

A VPN kill switch is a critical security feature that monitors your VPN connection in real-time. If your VPN connection unexpectedly drops, the kill switch immediately blocks all internet traffic from your device, preventing your real IP address and unencrypted data from being exposed.

Think of it as an emergency brake for your internet connection. The moment your VPN protection fails, the kill switch activates and keeps your data safe until the VPN connection is restored.

Why You Need a Kill Switch

VPN connections can drop for various reasons: unstable internet, switching networks, server issues, or even brief connectivity interruptions. Without a kill switch, your device would automatically reconnect using your regular, unprotected connection — exposing your real IP address and data.

Switching Networks

When moving from Wi-Fi to mobile data or between different Wi-Fi networks, the kill switch prevents any data leakage during the transition.

Sleep Mode Wake-Up

When your device wakes from sleep, the VPN might take a moment to reconnect. Kill switch keeps you protected during this time.

Server Maintenance

If a VPN server goes down for maintenance, the kill switch ensures you don't accidentally browse unprotected.

Unstable Connection

On unreliable networks, brief disconnections happen frequently. The kill switch catches every single one.

Kill Switch Types

Duckier offers flexible kill switch options to suit your needs:

System-Level Kill Switch: Blocks all internet traffic when VPN disconnects. Maximum security for complete protection.
App-Level Kill Switch: Only blocks specific applications you choose, allowing other apps to continue working normally.

Pro Tip: We recommend enabling the system-level kill switch for maximum security, especially when handling sensitive information or when privacy is critical.

Always-On Protection

Once enabled, the kill switch works silently in the background. You don't need to do anything — it automatically activates when needed and deactivates once your VPN connection is restored. Your privacy is protected 24/7 without any manual intervention.
