PureBoot is Purism’s cutting edge, complete secured boot process and combines a number of technologies including:

  • Neutralized and Disabled Intel Management Engine where only the code absolutely essential for the system to boot is left in the ME.

  • Coreboot the free software BIOS replacement.

  • A Trusted Platform Module (TPM) chip

  • Heads our tamper-evident boot software that loads from within coreboot and uses the TPM and the user’s own GPG keys to detect tampering within the BIOS, kernel, and GRUB config.

  • Librem Key our USB security token that integrates with Heads to alert the user to tampering with an easy “green light good, red light bad” process.

  • Integration between the Librem Key and LUKS disk encryption so you can unlock your disk with your Librem Key.
