Kill Switch
A VPN feature that instantly blocks all internet traffic if the VPN connection drops, preventing your real IP from being exposed.
A kill switch is a critical safety feature in VPN software. If your encrypted VPN tunnel unexpectedly disconnects, the kill switch immediately cuts your device's internet access to ensure no unprotected data leaks out.
Types of Kill Switches
- **App-level**: Blocks internet only for specific apps you select
- **System-level**: Blocks all device traffic — more secure but more disruptive
When It Matters Most
- Torrenting or P2P file sharing
- Accessing sensitive accounts on public Wi-Fi
- Journalists or activists in restrictive countries
- Any activity where IP exposure is a serious risk
FAQ
Do all VPNs have a kill switch?
Most premium VPNs include a kill switch, but it may not be enabled by default. Always check your VPN settings and turn it on manually.
Does a kill switch affect my internet speed?
No. A kill switch only activates when the VPN disconnects. It has zero impact on speed during normal operation.
