The NordVPN Kill Switch prevents data exposure if your VPN connection drops unexpectedly. Here’s how it works and why it’s essential.

What is a Kill Switch?

A kill switch blocks all internet traffic when the VPN connection fails, preventing your real IP address and unencrypted data from being exposed.

How NordVPN Kill Switch Works

Connection Monitoring

Continuously monitors VPN tunnel status for any disconnection.

Immediate Response

Blocks internet access within milliseconds of detecting VPN failure.

Automatic Restoration

Restores internet when VPN reconnects successfully.

Two Kill Switch Modes

App Kill Switch

Blocks specific applications from accessing internet when VPN drops. Useful for:

• Torrent clients
• Specific browsers
• Applications handling sensitive data

Internet Kill Switch

Blocks ALL internet traffic when VPN disconnects. Maximum protection for:

• Whistleblowers and journalists
• Users in restrictive countries
• Anyone requiring absolute leak prevention

Why You Need Kill Switch

VPN Connections Can Drop

Network changes, server issues, or software updates can interrupt VPN connections.

Seconds Matter

Even brief exposure can reveal your IP address to websites, ISPs, or surveillance.

You can’t manually react fast enough. Kill Switch responds instantly.
