## Projektgeschichte und Nutzung

killswitch is a macOS VPN kill-switch CLI that uses the `pf` firewall to block outgoing traffic when the VPN tunnel disappears.

### Projektgeschichte

The GitHub repository was created in 2016, with a 0.7.0 GitHub release published on 2019-03-09. The README explains the core design: write temporary `pf` rules to `/tmp/killswitch.pf.conf`, load them with `pfctl`, and avoid modifying the system default `/etc/pf.conf`.

### Adoptionsgeschichte

killswitch has narrower packaging than the other projects in this batch; the Homebrew formula documents it as a macOS VPN kill switch, and the project README focuses on local builds and root-required enable/disable commands.

### Wie es verwendet wird

Users run `sudo killswitch -e` to enable firewall rules, `sudo killswitch -d` to disable and restore default rules, or `killswitch --print` to inspect rules before applying them.

### Warum Paket-Nerds sich dafür interessieren

killswitch is notable as a small packageable security utility that exposes macOS `pf` behavior through a single CLI, useful for users who want a provider-independent VPN leak guard rather than an application-specific setting.
