| Open Access SQOUT

Open-Access SQOUT® provides a curated overview of unclassified quantum threat intelligence, illustrating how quantum communication systems can be compromised through both quantum-specific and classical attack vectors. It is designed as an accessible entry point into the rapidly evolving security landscape of quantum technologies.

The full SQOUT® platform goes far beyond this preview. It delivers a comprehensive, operational environment that combines a rich, structured threat intelligence database with advanced system design, threat analysis, and risk assessment capabilities.

With continuously expanding coverage, the SQOUT® knowledge base currently includes:

  • 114+ attack techniques and 119+ countermeasures, structured across the full attack lifecycle
  • 31 quantum protocols and their associated vulnerabilities
  • 120+ hardware components and 29+ software elements, mapped to threat scenarios
  • Modular system architectures linking components, protocols, and attack surfaces

Built on this foundation, SQOUT® enables you to:

  • Analyse threats in context through detailed mappings between techniques, protocols, components, and system architectures
  • Design secure quantum systems using an interactive system modelling environment (QBuilder)
  • Automatically identify vulnerabilities in your designs with the QAnalyser threat engine
  • Model multi-stage attack scenarios and calculate risk using QKill
  •  In the coming months we will also offer the possibility to perform structured, auditable risk assessments aligned with standards such as ISO 27005 (QAssessment)

While Open-Access SQOUT® shows what is possible, the full SQOUT® platform enables you to actively design, analyse and secure real-world quantum communication systems, making it the first quantum security risk assessment tool for QKD and other quantum communication systems.
