Great server hardware made better with PureBoot.

PureBoot: Secure Boot Process

We’ve taken some of the best server hardware and hardened it with PureBoot, our fully-auditable secure boot process that replaces the existing BIOS with coreboot, neutralizes and disables the Intel Management Engine, and adds tamper detection for the BIOS, kernel, and all files related to the boot process using keys fully in the owner’s control. Combined with our Librem Key at boot time, tamper detection is foolproof with an LED (designed to be bright enough to view over a security camera) that continually blinks red if the BIOS is tampered with.

Librem Key: Easy Security Verification

Librem Key The Librem Key is our USB security token that integrates with PureBoot to identify and alert you when your server has been tampered with. With two modes: green light good, red light bad you have instant easy security verification which can be monitored in person or remotely.

Saving Your Organization Time & Money

Our security team has spent hundreds of hours developing coreboot for some of the best server hardware to give your organization the most secure server on the market at fraction of the cost of doing it yourself.
