A Kill Switch automatically blocks all internet traffic the moment your VPN connection drops — protecting your real IP address from being exposed. Surflare enables Kill Switch by default, so you're always protected.

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.
Surflare enables Kill Switch automatically the moment you connect. No settings to find, no toggles to flip — your traffic is always protected.
Surflare's Kill Switch runs silently in the background, watching your VPN tunnel at all times.
You connect to a Surflare VPN server. Kill Switch automatically activates and begins monitoring the tunnel.
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.
Once the VPN tunnel is restored, Kill Switch lifts the block and your encrypted traffic resumes automatically.
VPN dropouts happen more often than most people realize. Without a Kill Switch, any of these common events can silently expose your real IP:
Moving between Wi-Fi networks, or switching from Wi-Fi to cellular, briefly disconnects the VPN.
Changing VPN servers creates a short gap between disconnecting from one and connecting to another.
Unstable internet, ISP issues, or high network congestion can cause momentary VPN tunnel failures.
When your laptop wakes from sleep, there's a brief window before the VPN tunnel is re-established.
Blocks traffic at the OS network layer, protecting every app simultaneously — not just the browser.
No settings required. Kill Switch is active from your very first connection without any manual setup.
Traffic is blocked within milliseconds of a VPN dropout — fast enough to prevent any data from leaking.
Surflare's Kill Switch keeps your real IP hidden at all times — automatically enabled, no configuration required.
