PQShield

PQShield develops post-quantum cryptography (PQC) hardware and software solutions designed to modernize the vital security systems and components of the world's technology supply chain against the threat of quantum computers breaking current cryptography methods. The company was the first cybersecurity company to develop quantum-safe cryptography on chips, in applications, and in the cloud, and its team has helped shape all of the first international PQC NIST standards. PQShield offers a mature PQC security suite including: PQMicroLib-Core (ultra-small cryptographic library for memory-constrained embedded systems, requiring as little as 5KB RAM), PQCryptoLib-Core (highly configurable software PQC library for classical, PQC, and PQ/T hybrid), PQCryptoLib-SDK (plug-and-play SDK for quantum-resilience in OpenSSL applications), PQPlatform-CoPro (secure coprocessor for easy PQC integration), PQPlatform-TrustSys (PQC-first Root-of-Trust system for secure post-quantum transition), and PQPerform hardware accelerators (Flare, Inferno, and Flex) delivering high-performance post-quantum cryptography with breakthrough key encapsulation performance. The company serves markets including semiconductors and manufacturing, identity and paymentech, military and aerospace, system integrators, automotive, industrial IoT, network and telecommunications, enterprise platforms, and healthcare. PQShield provides a four-step engagement model: discuss (guiding through PQC landscape), evaluate (assessing existing infrastructure risk and agility), design (creating end-to-end quantum-resilient solutions compliant with NIST standards), and implement (deploying solutions securely). The company differentiates itself through its deep involvement in NIST PQC standardization, its comprehensive hardware-software product suite, and its NCSC Assured Consultancy status. Founded in 2018 and headquartered in Oxford, United Kingdom, PQShield has raised approximately $65.3 million in a Series B round backed by Oxford University Innovation, Addition, Chevron Technology Ventures, Legal & General Capital, Oxford Science Enterprises, Bravos Capital, UKRI, Crane Venture Partners, Kindred Capital, and the University of Oxford.
