PQShield UltraPQ-Suite

PQShield UltraPQ-Suite is a comprehensive post-quantum cryptography solution suite providing quantum-safe hardware IP, software libraries, and root-of-trust security for protecting digital infrastructure against quantum computing threats. The suite addresses the urgent need for organizations to transition cryptographic systems to quantum-resistant algorithms following the August 2024 publication of NIST post-quantum cryptography standards and government mandates like NSA CNSA 2.0 requiring PQC migration by 2025. PQShield co-authored all four NIST-standardized PQC algorithms (ML-KEM, ML-DSA, SLH-DSA, and FN-DSA), providing unparalleled expertise in implementing quantum-safe cryptography across hardware, software, and cloud environments with certification-ready implementations aligned with FIPS 140-3, Common Criteria, SESIP, and PSA standards.

The UltraPQ-Suite is organized into three optimization pillars addressing different deployment requirements. Ultra Fast solutions like PQPerform-Lattice deliver high-performance cryptography for network infrastructure including firewalls, routers, and HSMs, achieving over 1 million key encapsulations per second. Ultra Secure implementations provide government-grade protection for critical infrastructure and defense applications with comprehensive side-channel countermeasures and fault tolerance. Ultra Small products like PQCryptoLib-Embedded offer the market's smallest PQC implementation for memory-constrained devices, embedded systems, and IoT devices requiring efficient end-to-end encrypted communications. The flagship PQPlatform-TrustSys provides a PQC-first root-of-trust architecture for ASIC and FPGA hardware, enabling secure boot, lifecycle key management, and comprehensive key origin tracking with minimal integration effort for compliance with evolving regulations requiring complete phase-out of RSA by 2035.

PQShield was founded in 2018 in Oxford, UK and has raised $37M in Series B funding led by Addition, with backing from Chevron Technology Ventures, Legal & General, and Oxford Science Enterprises. The company employs 70+ cryptography experts and engineers across 10 countries and maintains active partnerships with organizations including Signal Foundation (providing pro bono PQC), Quside (QRNG integration), and major OEM manufacturers. PQShield's products are deployed across automotive (secure vehicle communications), financial services (payment security), telecommunications (5G/6G encryption), semiconductor manufacturing (supply chain security), healthcare (medical device protection), and government/defense sectors protecting classified data against harvest-now-decrypt-later attacks. The company was recognized in The Sunday Times 100 fastest-growing UK tech companies and received NCSC PQC Assurance for critical UK infrastructure protection.
