ThreatModeler Nexus vs ThreatZ

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.

ThreatZ is an automotive cybersecurity management platform for OEMs and Tier-1 suppliers tracking vehicle security and supply-chain evidence. It brings TARA, software bills of materials, attack paths, incidents and compliance evidence into a knowledge graph. Threat modeling supports STRIDE TARA, AI-assisted threat scenarios and attack paths with feasibility ratings. ThreatZ generates work products for ISO/SAE 21434, UN R155 and GB 44495-2024; the last requires PRC-region deployment. Its integration list includes more than 30 tools and formats, among them Vector CANoe, MATLAB System Composer, Jira, GitHub and SonarQube. Data interchange options include ReqIF, SARIF, OpenXSAM, STIX, AUTOSAR, PDF, CSV and Excel. Team and Professional are hosted AWS Marketplace subscriptions, while Enterprise supports private cloud, on-premises and air-gapped deployment. The listed Team plan costs $1,199 a year, billed annually, and allows up to three projects. Professional is listed at $499 a year, billed annually, for 5–50 users and up to 15 projects; Enterprise is $100 a year with custom billing and unlimited projects and users. A free four-week trial uses sample vehicle data; Professional and Enterprise trials require approval.
