PROFESSIONAL NETWORK
Join the World's Largest Community of Quantum Security Professionals
QSECDEF brings together the practitioners, policymakers, and vendors actively shaping the post-quantum transition. Members share early intelligence on tooling, procurement developments, and regulatory shifts before that information reaches the public domain. This is the professional network the field converges on.
More than 1,200 members from 40+ countries, including Five Eyes governments, NATO member institutions, and the leading quantum vendors are already part of the community.
EVENT INVITATIONS
Get Early Invitations to Quantum Security Events and Webinars
QSECDEF hosts closed briefings, practitioner webinars, and in-person events attended by defence agencies, central banks, and critical infrastructure teams. Members receive invitations before public registration opens. Several events are members-only and never open to the public.
600+ organisations across 40+ countries are represented in our member community, including defence ministries, NATO institutions, and Five Eyes government agencies.
THREAT INTELLIGENCE
The Briefing That Closes Your Quantum Threat Picture
Most organisations have a PQC roadmap. Fewer have a reliable signal on where the actual threat timeline sits, which vendors' claims hold up under scrutiny, and what peer organisations at your maturity level are doing. QSECDEF membership exists to close that gap. One briefing cycle has changed procurement decisions at organisations you would recognise.
Members include CISOs, heads of cryptography, and national security advisors from 40+ countries. The Five Eyes and NATO institutions read what we publish.

More than 50 Industry members across fifteen countries provide capability spanning every technical domain in the post-quantum transition. Eighteen hold active PQC implementation work, including NIST submission authors and Round 4 finalists. Accreditations across the network include Common Criteria EAL 4+, FIPS 140-3, FedRAMP, NCSC-recognised schemes, and IEC 62443. Members participate in NIST PQC, ETSI, ISO TC307, IETF, and IEEE.
