OpenTitan-based silicon security platform
No salary listed
Boston, MA, USA
Hybrid
zeroRISC commercializes OpenTitan-based silicon Root of Trust technology to provide silicon, software, and cloud services that secure devices from boot to runtime. Its Integrity Management Platform verifies at boot that devices run authorized code and stores an immutable hardware fingerprint in silicon, while enabling policy management through cloud services. It differentiates itself by offering a full-stack, open-source-rooted security solution rather than just silicon, aligning hardware, embedded OS, and cloud controls under one platform. The goal is to make foundational hardware security transparent and accessible, giving data centers, ICS/OT, IoT, and edge devices centralized control over security policies and verifiable boot integrity.

ZeroRISC has released a complete open-source cryptographic hardware and software stack for both classical and post-quantum operations. The release includes the Cryptolib embedded cryptography library, an Asymmetric Cryptography Coprocessor, and hardware accelerators for symmetric operations. The multi-year collaboration with research institutions achieved 6–9x speedups for ML-KEM and ML-DSA algorithms whilst improving maximum operating frequency by 36–75% with near-zero area cost. Memory optimisations reduced ML-DSA stack usage by over 90%. Cryptolib supports classical algorithms including AES, SHA2/SHA3, RSA and elliptic curve cryptography, alongside NIST-standardised post-quantum algorithms ML-KEM, ML-DSA and SLH-DSA. The consortium will present results at Real World Crypto 2026 in Taipei on 9 March, demonstrating production-grade post-quantum cryptography for embedded systems.
ZeroRISC, the leading open-source silicon supply chain integrity solution, today announced the appointment of Zakir Durumeric, Stanford Professor and Censys Founder, and David Gammon, CEO & founder of Rockspring, to its Board of Directors.
ZeroRISC announced the close of its oversubscribed seed round with $10 million in new funding, led by Fontinalis Partners.
ZeroRISC, a silicon supply chain integrity solutions startup, raised $10M to expand its open-source silicon security platform. Founded by Dominic Rizzo in 2023, ZeroRISC offers a commercial-grade chip based on the OpenTitan root of trust and an Integrity Management Platform. The platform includes silicon hardware, embedded software, and cloud tools, with post-quantum cryptography for future-proof security. The funding round was led by Fontinalis Partners, with participation from several investors.
