VPN Kill Switch — Your Safety Net Against IP Leaks

What Is a VPN Kill Switch?

A kill switch is a critical VPN security feature that automatically blocks all internet traffic if your VPN connection unexpectedly drops. Without it, a brief disconnection could expose your real IP address and unencrypted data.

How It Works

The kill switch monitors your VPN connection. If it detects a drop, it immediately blocks all outgoing network traffic at the firewall level. Once the VPN reconnects, traffic resumes through the encrypted tunnel.

Types of Kill Switches

• App-level: Closes specific applications when VPN drops
• System-level: Blocks all internet traffic — more secure

LimeVPN uses a system-level kill switch on all platforms to ensure no data ever leaks outside the tunnel.
