PQShield

PQShield is a cryptography company focused on building the foundations for a quantum-safe future. The firm, which originated as the largest spinout from Oxford University's Mathematical Institute in 2018, is home to one of the world's largest commercial groups of post-quantum cryptographers. Its work spans the technical domains of post-quantum cryptography, hardware security, and quantum computing.

The company's product portfolio addresses the need to secure the entire digital stack against future quantum threats. It was the first cybersecurity firm to develop quantum-safe cryptography across three critical layers: as Hardware IP for chips, as Software libraries for applications, and as Cloud solutions. This positions it to serve a range of industries that require long-term data security.

PQShield's solutions are applied across multiple high-stakes sectors. Its technology is used in semiconductors, military and aerospace systems, identity and payment technology, telecommunications, automotive, and industrial IoT, where protecting data integrity over extended periods is essential.
