About QuDef BV
QuDef works on the security of quantum technology. The Delft firm provides assurance, risk assessment, threat intelligence, auditing, education and consulting for organisations integrating quantum communication and computing into existing classical infrastructure. Its leadership team draws on R&D, quantum communication and defence applications, and on strategic advisory roles for organisations such as NATO, the European Commission and EUSPA.
At the centre of the practice is SQOUT, a quantum technology threat intelligence and knowledge platform. It is organised like a TTP framework: tactics, techniques, procedures and countermeasures, each linked to quantum protocols, algorithms, hardware, software, products and security frameworks, including ETSI QKD PP and ISO/IEC requirements. An open-access version covering QKD is published at sqout.qudef.com.
Services built on SQOUT include compliance checks against standards and security frameworks, risk and threat assessment, security evaluations and audits, adversary emulation, red and blue teaming and incident investigation. Typical clients are QKD manufacturers and integrators, cyber security authorities approving quantum networks, and certification bodies mapping standards to quantum device components.
