zeroRISC Integrity Management Platform

zeroRISC provides a commercial cloud security service built on the OpenTitan open-source silicon root of trust (RoT) project. The company was founded in 2023 by original OpenTitan project team members from Google, including founder and CEO Dominic Rizzo.

The company's platform combines silicon, software, and services to deliver cloud-based secure device management that operates below the operating system level. The solution is designed for data centers, operational technology/industrial control systems (OT/ICS), and IoT technologies. The platform enables secure ownership transfer and provides transparency and reliability through its open silicon foundation.

zeroRISC's approach centers on the principle that security must start at the silicon level. By building on OpenTitan, an open-source silicon root of trust, the company provides hardware-based security assurances that serve as a foundation for system security. The platform functions as a drop-in solution that integrates silicon components with management software and cloud services.

The company raised $5 million in seed funding in October 2023, led by Cambridge Angels, with participation from ARM founder Herman Hauser and former ARM president Pete Hutton, along with other private investors.
