About Quantum Security Defence

Quantum Security Defence (QSECDEF) connects government, industry and academia to work through the quantum transition. More than 1,500 professional members from over 900 organisations across 40 countries use it as the decision layer for building capability in deep tech cyber security. Its scope is international. It is funded by its members.

Its work spans quantum cybersecurity, quantum-secure communications and integrated quantum computing. Members get weekly expert lectures, certificated courses, private briefings, practical tools and a peer network. Engagements follow three models: a global expert network embedded in your team, capability mapping for delivery, and enablement programmes that run from board briefings to engineering certifications.

QSECDEF does not sell hardware, software or services in the quantum stack. Its advice is not tied to a product line. It works with defence ministries, governments, central banks, critical infrastructure operators and the vendors building the quantum supply chain, and is a UK limited company run as a global membership association.
