Key Features

Production-ready protection for your firmware

Hardware-Level Operation

Runs before BIOS/UEFI, completely independent of the operating system. Cannot be disabled by malware or OS-level attacks.

Automatic Recovery

Detects boot failures and automatically recovers from USB device. No manual intervention required.

Two-Backup Rotation

Maintains exactly 2 rotating firmware backups (A.bin and B.bin) with automatic rotation every 10 minutes.

Cryptographic Security

All firmware images are cryptographically signed and verified. Prevents unauthorized firmware installation.

Cross-Platform CLI

Works on Linux, Windows, and macOS. Simple command-line interface for all operations.

Safe Uninstall

Multi-step confirmation process prevents accidental removal. Validates system health before uninstalling.

Architecture
