Threagile vs ThreatZ

Threagile is an open-source toolkit for agile threat modeling. It represents architecture and assets in YAML and checks those models against risk rules, then produces reports of potential risks and recommended mitigations. Mitigation status can be recorded in the YAML model so reports reflect current progress. The toolkit also generates data-flow diagrams and supports Excel and JSON output. Teams can run it from the command line, in Docker, or as a REST server. Models can be edited in developer IDEs and tracked in Git, while custom risk rules can be written as YAML scripts without compiling Go code. A web playground analyzes YAML models and links to schema and API resources; a GitHub Action can run the tool against a repository model file. Threagile is free under the MIT License and supports API, Linux, self-hosted, and web use. The project describes itself as developer-friendly for agile projects and DevSecOps workflows. Its repository says current UI attempts are not ready, and support requests can be raised as GitHub discussions or issues.

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.
