PQShield is a University of Oxford spin-out that develops post-quantum cryptographic IP and software for chips, embedded systems and enterprise products, aligned with NIST post-quantum standards.
It raised a $37M Series B in June 2024 led by Addition, and reported customers include AMD, Microchip and Lattice Semiconductor.
Innovation Matrix Assessment
Research-led IP covering hardware and software across standardized algorithms.
Gives product makers a path to quantum-resistant implementations.
$37M Series B (Jun 2024), about $70M total; semiconductor customers reported.
Embeds PQC at silicon level, which few vendors do.
Standards alignment is credible but independent real-world deployment evidence is limited.
The quantum transition is a certain multi-year requirement.
Why CISOs Should Care
Helps organizations and suppliers meet post-quantum migration requirements in the chips and products they depend on.
What Makes It Different
Hardware-level PQC IP together with software and research, rather than a software-only overlay.
The Matrix Verdict
68/100 — INCREMENTAL INNOVATOR
PQShield is an Incremental Innovator at the upper end, with strong relevance and a distinctive hardware focus; evidence of deployment efficacy is still emerging.
Editorial Note: Claims vs. Verified Findings
Customer names are from press coverage rather than named case studies. The funding is press-confirmed.
