**Dónde en FireAI:** Protection › Kill switch

Cut your Mac off the internet in one click when something feels wrong.

“Cut this Mac off from the internet in one click.” Turning it on refuses new connections to anything outside your home or office network; printers, shared drives and this Mac keep talking to each other.

> **Warning:** The kill switch refuses new connections; it doesn’t tear down ones already open. It also needs Protection to be on — it’s disabled while Protection is paused.

It’s also reachable from the menu bar, so you don’t need to open the main window to use it. For everyday strictness instead of an emergency stop, see [security modes](https://hisnlabs.com/fireai/en/docs/security-modes).
