What is a VPN Kill Switch?
A VPN kill switch is a security feature that automatically disconnects your device from the internet if your VPN connection drops. This prevents your real IP address, DNS requests, and online activity from being exposed to your ISP, hackers, or surveillance agencies.
How Does a Kill Switch Work?
When your VPN connection fails, the kill switch detects the disruption and immediately:
- Blocks all internet traffic until the VPN reconnects.
- Closes specific apps (in app-based kill switches) to prevent leaks.
- Alerts you about the connection drop, so you can take action.
Without a kill switch, your data could be transmitted over an unsecured connection, leaving you vulnerable to tracking, hacking, or censorship.
Types of VPN Kill Switches
Not all kill switches are created equal. Here are the two main types:
1. System-Wide Kill Switch
- What it does: Cuts off all internet access if the VPN disconnects.
- Best for: Maximum security, especially on public Wi-Fi.
- Example VPNs: NordVPN, Surfshark.
2. App-Specific Kill Switch
- What it does: Only shuts down selected apps (like torrent clients or browsers) if the VPN fails.
- Best for: Users who need certain apps to stay online while others remain protected.
- Example VPNs: ExpressVPN, CyberGhost.

1. Prevents IP and DNS Leaks
Even a brief VPN disconnection can expose your real IP address. A kill switch ensures no data is sent outside the encrypted tunnel.
2. Essential for Torrenting and P2P Sharing
If your VPN drops while torrenting, your ISP could detect and throttle your connection”or worse, send a copyright notice.
3. Protects Against Government Surveillance
In countries with strict internet censorship (like China or Iran), a kill switch prevents accidental exposure to monitoring.

Remote workers handling confidential information can’t afford a VPN failure leaking company data.
