What it is

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.
