swiftGuard

swiftGuard is a macOS tray‑level utility that continuously watches USB ports for any device activity, including while the system is asleep. When an unauthorized device is detected or a previously connected device is removed, the application can automatically trigger a system shutdown or hibernation, providing an anti‑forensic safeguard for the host machine.

The tool lets users maintain a whitelist of approved USB devices, ensuring normal operation for trusted peripherals. Configuration options include selecting the response action, setting a countdown timer to cancel the shutdown, and enabling auto‑start at login. It runs discreetly in the system tray, consumes minimal resources, and contacts the internet only to check for updates.

swiftGuard is released under an open‑source license, offering transparency and the possibility for community contributions. It is positioned as a lightweight, privacy‑focused solution for users who need to protect their macOS systems from unauthorized USB access.
