In their own words
CYMETRIS
CYMETRIS is a cyber risk analysis and TARA platform for work across a product lifecycle. Its guided workflow follows ISO/SAE 21434 and applies automated consistency and logic checks. Teams can inspect attack paths interactively and map risks to components in system architecture, with risk prioritization, collaborative review, templates, frameworks, and multiple modeling methods. CYMETRIS Lite generates audit-ready reports for ISO/SAE 21434 and UN R155. The maker describes AI assistance through MCP for importing architectures, identifying assets, developing attack vectors, and querying TARA datasets in natural language. A public API is intended to connect requirements, architecture, PLM, ticketing, ALM, and reporting systems. Vulnerabilities can be imported from CVE databases, vendor advisories, or internal analyses and mapped to affected components; this capability is described as a selected-customer prototype. Access is available through web, API, or self-hosted deployment. Lite costs €99.00 per month, includes one full TARA project, and allows up to five active projects.
