Stay safe on unreliable networks
Wherever you are, our kill switch continuously monitors your connection to our VPN servers. If the connection accidentally drops, the kill switch immediately blocks all traffic from your device, keeping your IP address and DNS queries secure.
Kill switch makes sure you’re always secure
Our kill switch does not impact your connection speed or browsing and provides a valuable last line of defense. It ensures your browsing remains private if your internet provider has a brief outage or if you switch WiFi networks.
Stay in control
You can turn our kill switch on when accessing sensitive information or use our permanent kill switch when you want to be sure your internet connection is always protected by Proton VPN.
