VPNKill
Your VPN has a kill switch. macOS has a loophole.
Every time your Mac switches networks — Wi-Fi to hotspot, office to home, sleep to wake — there's a brief window where connections slip outside your VPN tunnel. VPNKill closes it: if traffic isn't going through your VPN, it isn't going anywhere.
- Seals the reconnect-gap leak
- Guards DNS, not just web traffic
- Works below the app layer, always on
Why VPNKill
Not another VPN, not a suite — a hardware-style kill switch for the VPN you already use.
One job, done right
It blocks every non-VPN connection at the packet layer. That's the whole product, and it's bulletproof.
Works with any VPN
WireGuard, OpenVPN, IKEv2, corporate clients — VPNKill doesn't care who runs your tunnel, only that traffic stays inside it.
Lives in your menu bar
One click on, one click off. A glance tells you the state. Pause for a minute when you need to — it re-arms itself.
Native and lightweight
No accounts, no subscriptions, no traffic inspection. It blocks, it doesn't watch — nothing ever leaves your Mac.
Made for people who can't afford a single leak
- Remote workers under a corporate "VPN always on" policy
- Region-locked accounts and tools that get flagged by a single request from the wrong IP
- Frequent network hoppers — café Wi-Fi, iPhone hotspot, hotel networks
- Privacy-conscious users who want a guarantee, not a promise
