Our Mission

Quantum computing will fundamentally change how information is secured. Organisations that prepare now will transition smoothly. Those that wait will face costly, rushed migrations under pressure.

QSECDEF exists to ensure that transition happens safely. We provide the training, expert networks, and strategic partnerships that organisations need to adopt quantum technologies with confidence. Our members include cryptographers, security architects, defence planners, policy advisors, and technology vendors from more than 40 countries.

We are not a vendor. We do not sell quantum hardware or software. We are a membership organisation that connects the people and knowledge required to make quantum adoption work.

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.
