PQShield: Post-Quantum Cryptography for European Strategic Autonomy

A new class of cyber threat is emerging in the form of quantum computers – machines powerful enough to break the encryption safeguarding Europe’s critical communications. In this climate, the race is on to upgrade Europe’s security with “quantum-resistant” cryptography before adversaries exploit the quantum advantage.

Enter PQShield , an Oxford-born deep-tech company at the forefront of post-quantum cryptography. Founded in 2018 by a University of Oxford cryptographer, PQShield has rapidly become a key innovator in quantum-safe encryption hardware and software.

This analysis answers: What post-quantum, quantum-resistant cryptography hardware and software does PQShield provide? How mature is PQShield's technology and how does it fit European strategic-autonomy needs to upgrade encryption before quantum adversaries emerge? Who are PQShield's partners and customers, and how does its Oxford academic origin support standardisation and dual-use adoption? What dependencies, IP position or capability gaps affect PQShield's role in securing Europe's critical communications?
