What is a VPN Kill Switch?
A VPN Kill Switch is a security feature that monitors your VPN connection in real time. The moment the VPN tunnel drops — due to a server switch, network change, or unexpected disconnect — the Kill Switch immediately cuts off all internet access.
Without a Kill Switch, a VPN dropout can silently expose your real IP address and unencrypted traffic to your ISP, network operator, or any observer. The Kill Switch prevents this from ever happening.
Surflare's Kill Switch operates at the system network level, ensuring no data leaks through any app — browser, torrent client, or messaging app — during a VPN interruption.
Turn It On with One Toggle
Kill Switch is off by default. Open Surflare, go to the Home tab, and switch on Kill Switch. The setting is saved, so protection stays on until you turn it off.
- One toggle on the Home screen
- Available on Windows, macOS, Linux, and routers
- Stays on across reconnects and app restarts
How Does the Kill Switch Work?
Surflare's Kill Switch runs silently in the background, watching your VPN tunnel at all times.
Switch on Kill Switch on the Home screen, then connect to any Surflare server.
Kill Switch constantly checks the VPN connection state. Normal traffic flows through the encrypted VPN tunnel.
If the VPN tunnel breaks for any reason, Kill Switch instantly blocks all network traffic within milliseconds.
Choose Restore Internet in the Surflare app to lift the block, then connect to the VPN again.
When Does a VPN Connection Drop?
VPN dropouts happen more often than most people realize. Without a Kill Switch, any of these common events can silently expose your real IP:
- Network switching
Moving between Wi-Fi networks, or switching from Wi-Fi to cellular, briefly disconnects the VPN.
- Server switching
Changing VPN servers creates a short gap between disconnecting from one and connecting to another.
- Connection instability
Unstable internet, ISP issues, or high network congestion can cause momentary VPN tunnel failures.
- Device sleep/wake
When your laptop wakes from sleep, there's a brief window before the VPN tunnel is re-established.
