Our Mission

QSECDEF was built for the moment security leaders ran out of good independent advice. Post-quantum migration made that moment urgent: organisations are making cryptographic architecture decisions without practitioner context, under regulatory timelines that are tightening, in a vendor market with a clear commercial interest in the outcome. The same conditions now apply to AI Security. Governance frameworks are immature. Threat models are contested. The decisions being made now about AI Security architecture will be difficult to reverse.

These are not two separate problems. They are two current expressions of the same underlying reality: infrastructure-scale security decisions are being made without an independent practitioner layer to make them well. QSECDEF is that layer. In both domains.

The Quantum Adoption Path

1

Secure Our Infrastructure

Cryptographic audit, PQC migration, quantum risk assessment

2

Deploy Hybrid Quantum Computing

Classical + quantum co-processing, early advantage workloads

3

Integrate and Enable

Quantum-native applications, workforce readiness, standards adoption

4

Major Disruption

Full-scale quantum computing transforms industries and economies

Organisations that secure their infrastructure now will be ready for what comes next. Those that wait face costly, high-pressure migrations.

Governance

Legal status

UK Limited Company

Organisation type

Global Membership Association under UK Governance

Financial reporting

Financial report to be published Q2 2025 (first full year of operation)
