KAVACH vs ThreatModeler Nexus

KAVACH is an automotive cybersecurity engineering workspace connecting vehicle architecture to traceable cybersecurity evidence across ISO/SAE 21434 workflows. Its TARA process links assets, damage and threat scenarios, attack paths, risk assessment and treatment, security goals, controls, and evidence. The workspace includes architecture context, attack-tree editing, a traceability hub, vulnerability monitoring, a cybersecurity case, an R155 compliance matrix, and report generation. SBOM and vulnerability signals can connect affected components with assets, threats, and treatment decisions. The current release focuses on ISO/SAE 21434 Clauses 5–15, UNECE R155/R156 evidence, AIS 189/AIS 190 readiness, and post-production monitoring. Deployment choices are a customer-controlled desktop workspace, on-premise deployment, or a customer-dedicated EU cloud VPC. Manual engineering, deterministic automation, and optional private AI are available. Generated work products are structured drafts requiring engineer review and customer approval. Pricing is scoped per programme.

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.
