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.
