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.

Quantum Research Institutes, National Labs, and Consortia
Quantum research institutes, national labs, and consortia. QSECDEF independent directory covering academic spin-outs and government quantum programmes.
Every commercial quantum vendor started somewhere. The companies and institutions on this tab represent the pre-commercial tier: university spinouts whose primary revenue is grant funding, national laboratories commercialising IP through licensing and technology transfer, and quantum consortia coordinating multi-institution research programmes. This is where the vendors on the Compute, Communications, and Sensing tabs were ten years ago. It is where tomorrow's commercial vendors are taking shape.
Three sub-populations make up the Research tab. University spinouts and early-stage research entities hold the primary commercial listing type. They have a founding story rooted in academic research, typically have published their core IP before commercialising it, and are often still running a parallel grant-funded research programme alongside their commercial activity. National laboratories and government research institutes — DLR, TNO, TII, CEA-Leti, MIT Lincoln Laboratory, NPL, the Rutherford Appleton Laboratory — carry informational listings in this tab: reference profiles that reflect their role as primary research producers and frequent technology transfer partners. Quantum consortia and membership bodies — QED-C, QuIC, UKQuantum, the NQCC, Q-NEXT, the Chicago Quantum Exchange — carry informational listings too: their function is coordination and convening at the programme level, and they are useful reference points for anyone mapping the institutional landscape.
The primary reason to track this tab is early signal. A spinout that publishes a strong result on error correction or quantum networking today may be a procurement target in three to five years. Members using QSECDEF for strategic intelligence will find more value here than those looking for a vendor to contract with this quarter.
