Engineering confidence in critical systems
Tunic Cyber brings cybersecurity engineering, threat modelling and risk assurance together to help organisations make defensible decisions about critical systems.
We are developing the Cyberworthiness Modeling Suite (CMS): a connected workspace for understanding threats, evaluating controls and tracing the reasoning behind cyber risk decisions.
Cyberworthiness Modeling Suite
From system context to defensible risk decisions.
CMS connects assets, zones, conduits and dataflows with misuse cases, malicious activities, attack trees, risk models and security controls. Its purpose is to keep the reasoning behind an assessment visible and connected.
MODEL THE SYSTEM — Understand operational technology and critical-system boundaries using IEC 62443 concepts.
TRACE THE THREAT — Follow threat scenarios through attack paths to the assets and controls that matter.
EXPLORE THE RISK — Use Monte Carlo simulation to examine uncertainty and residual risk under explicit assumptions.
SUPPORT THE DECISION — Compare control options and retain traceability for review and assurance reporting.
CMS is in active development as we prepare for release. Contact us to discuss demonstrations, evaluation opportunities and your use case.
