VPN Kill Switch: What It Is and Why You Need It
A VPN kill switch blocks internet traffic if the VPN drops so your real IP is never exposed. Learn how it works and why it matters.
Get KloxVPNA VPN kill switch (sometimes called network lock) is a feature that blocks all internet traffic on your device if the VPN connection drops. This prevents your real IP address and unencrypted data from being exposed during reconnection or connection failures.
Why Kill Switches Matter
When a VPN disconnects, your device may fall back to your normal connection. Until you notice and reconnect, your traffic and real IP are visible to your ISP and local network. A kill switch stops any traffic until the VPN is connected again.
How It Works
The VPN client monitors the tunnel. If it detects a drop, it blocks outbound traffic at the firewall or network level. Some implementations block all traffic; others allow you to allow-list certain apps. When the VPN reconnects, traffic is allowed again.
KloxVPN Kill Switch
KloxVPN includes a kill switch so that if the connection drops — on unstable WiFi, mobile handoff, or server issues — your device does not send traffic over your real connection until the VPN is back up.
