en.Wedoany.com Reported - On June 2, 2026, Delft-based cybersecurity company QuDef announced the commercial launch of its SQOUT® quantum threat intelligence and security assessment platform. This tool is designed to secure quantum key distribution (QKD) and post-quantum network layers, providing chief information security officers (CISOs), risk managers, and red and blue security teams with an environment for modeling, assessing, and mitigating hardware- and protocol-specific vulnerabilities. As quantum communication networks transition from laboratories to operational systems in aerospace, defense, and national critical infrastructure, SQOUT® aims to address the resulting implementation gaps.
Although QKD methods, including BB84, BBM92, continuous variable (CV-QKD), and measurement-device-independent (MDI-QKD) protocols, maintain mathematical proofs of security under ideal parameters, physical implementations introduce different hardware attack vectors. Real-world networks face threats such as physical side-channel leakage, detector blinding, Trojan horse optical reflection probing, and phase remapping defects. SQOUT® organizes these threat vectors into sequential kill chains using a structured tactics, techniques, and procedures (TTP) matrix, which correlates over 114 attack techniques with more than 119 hardware-level countermeasures.
The software framework operates through four core assessment modules. The QBuilder module is an interactive system modeling layout for mapping physical, electronic, and protocol-level attributes of network components such as single-photon detectors and interferometers. The QAnalyser module is a vulnerability scanning engine that reviews architectural layouts created in QBuilder, identifying unmitigated side channels and protocol violations. The QKill module is an attack scenario simulator for modeling multi-stage hacker attack paths and calculating risk indices using geometric mean probability aggregation. The QNetwork module is a planning module designed to extend threat assessments to larger distributed multi-node quantum network topologies.
The platform offers multiple infrastructure deployment modes to accommodate different commercial and confidential security parameters. Organizations can access the software through a hosted software-as-a-service (SaaS) web architecture, deploy it as a local virtual machine within air-gapped sovereign networks, or purchase it via SQOUT®-as-a-Service for targeted audit engagements. By directly mapping optical and physical attack paths to actionable engineering mitigations, the platform provides an empirical auditing tool for national testing bodies, system integrators, and network operators—such as those managing the European Quantum Communication Infrastructure (EuroQCI) or the Eagle-1 satellite constellation—to establish verifiable, risk-compliant quantum security frameworks.
