AutoSec TARA Suite vs ThreatModeler Nexus

AutoSec TARA Suite is a pilot automotive threat-modelling and risk-management platform for analyst-led workflows aligned with ISO/SAE 21434 and UN R155 activities. Its analysis moves through item definition, asset and boundary identification, threat scenarios, attack analysis, impact assessment, and risk determination. Candidate threat scenarios are generated for analyst review and mapped to STRIDE categories. Risk assessment considers safety, financial, operational, and privacy impacts, then calculates attack potential to determine risk. Listed outputs include traceability matrices, PDF and Excel compliance bundles, and VSOC detection rule exports. Deployment options include analyst-led engagements, managed evaluation instances, and self-hosted customer instances. Controlled self-hosted evaluations and technical demonstrations are available on request. The suite is designed to support ISO/SAE 21434, UNECE R155, and ISO 26262 activities, but it does not certify products or organisations. Pricing is available on request.

ThreatModeler Nexus is an agentic platform for secure design and governed threat modeling across applications, cloud and hybrid architectures, devices, and operational technology. Its Secure Design Graph connects architectures, threats, controls, compliance requirements, and security decisions. System Mapping, Graph, and Reporting agents operate on that graph. Supported methods include STRIDE, PASTA, and CSA MAESTRO for agentic systems, and findings map to more than 180 regulatory and security frameworks, including NIST, ISO 27001, PCI DSS, HIPAA, DORA, and the EU AI Act. A built-in MCP Server checks pull requests and commits against the current threat model and returns threats, requirements, and mitigations in developer workflows. Integrations include infrastructure tools, cloud providers, code platforms, ServiceNow, and ArmorCode. Customers can connect their own AI model, with a deterministic framework governing output. Web, API, and self-hosted environments are listed. A free Community Edition is available; the ThreatModeler license costs $4,000 a year on a 12-month contract. Additional AWS infrastructure costs may apply.
