CYMETRIS review
A focused TARA platform for automotive teams managing ISO/SAE 21434 risk.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
CYMETRIS is a threat modeling and cyber risk analysis platform for security engineers, product security teams, and cybersecurity consultants. Its strongest fit is automotive product security, where guided Threat Analysis and Risk Assessment workflows, architecture mapping, risk scoring, attack-path visualization, and ISO/SAE 21434 reporting support structured analysis across the product lifecycle. It also targets regulated environments including defence, IoT, industrial systems, aerospace, and healthcare.
Pricing is organized around CYMETRIS Lite and CYMETRIS Enterprise. Lite costs €99 per month and includes the guided TARA workflow, consistency and logic checks, interactive attack-path visualization, automatic ISO/SAE 21434 and UN R155 reports, API and integration access, and ticket-based support. The plan supports up to five active projects. Enterprise adds individual project bundles, unlimited users, cross-organization collaboration, vulnerability management, vertical TARA integration, enterprise toolchain connectors, and priority support with a dedicated contact and SLA.
The platform’s ecosystem fit is a significant consideration for teams with established engineering toolchains. Integrations include PLM, ALM, MBSE, Jira, Codebeamer, and Enterprise Architect, while API access and self-hosted deployment support broader implementation choices alongside its web platform. CYMETRIS also includes role-based access, configurable risk matrices, continuous lifecycle analysis with versioning, and AI-assisted TARA functions through MCP integration. Choose it when automotive compliance workflows, attack-path analysis, and traceable collaboration are central requirements. Teams seeking a free plan or a smaller project-only threat modeling tool should look elsewhere.
