What it does
Kicksecure is a security-focused Debian-based operating system with documented hardware, USB and virtual-machine deployment choices.
Kicksecure changes the operating-system baseline rather than adding one utility. Its site offers hardware, virtual-machine and Debian conversion arrangements, so select the model around the device and recovery plan first. One documented layer is USBGuard policy for devices attached after boot. The project explicitly says that this does not stop electrical-damage attacks or filter keystrokes from an already allowed device. The hardened baseline still needs updates, trusted peripherals and application-specific administration.
