Monitors your tunnel
KeenVPN continuously checks that your encrypted connection is live and healthy.
KeenVPN's kill switch blocks all internet traffic the instant your connection falters, so nothing leaks while it reconnects. On by default, on every plan.
A VPN kill switch is a safety net. If your encrypted connection drops, a common thing on public Wi-Fi or when switching networks, your device would normally fall back to the open internet, briefly exposing your real IP address and activity.
The kill switch stops that. It watches your VPN connection and, the moment it drops, blocks all traffic until the secure tunnel is back. You stay private through the gap, not just around it.
Three things happen automatically, you never have to think about it.
KeenVPN continuously checks that your encrypted connection is live and healthy.
If the tunnel drops, all internet traffic is blocked in milliseconds, before anything can leak.
Once the secure connection is back, your traffic resumes on its own. No manual reconnect.
Your real IP and DNS requests can't leak during a drop, so you're never briefly visible.
Café, airport and hotel networks drop constantly. The kill switch keeps those gaps covered.
Uploads, logins and client work stay protected even mid-transfer if the connection stutters.
It's on by default and works quietly in the background. Nothing to enable, nothing to manage.
The kill switch isn't an add-on or a premium upgrade. Like all KeenVPN protection, it's standard on every plan, which also earns perks and is backed by the 100-day guarantee.
