PQShield is a cryptography company specializing in post-quantum cryptography (PQC) — the development of cryptographic algorithms and solutions designed to be secure against attacks from quantum computers. The company focuses on providing quantum-safe and quantum-resistant cryptographic technologies to organizations that need to transition their security infrastructure away from classical cryptographic standards before quantum computing renders them vulnerable. This area of work is sometimes referred to as "crypto agility" or "quantum migration." PQShield's offerings span multiple deployment contexts: - Hardware-level cryptographic IP for semiconductor and chip manufacturers - Software cryptographic libraries for embedded systems, firmware, and applications - Consulting and advisory services to help enterprises and governments assess and plan their migration to post-quantum standards Their target markets include semiconductor companies, hardware manufacturers, defense and government agencies, financial institutions, and enterprise technology vendors seeking to embed PQC into their products and infrastructure. PQShield's work is aligned with standardization efforts led by bodies such as NIST (National Institute of Standards and Technology), which has been developing and finalizing post-quantum cryptographic standards. The company contributes to and tracks these standards to ensure its solutions remain compliant and interoperable. The company is headquartered in Oxford, United Kingdom, and operates as a deep-tech cryptography firm founded out of academic research in the field of lattice-based and other post-quantum cryptographic schemes.
