IriusRisk vs ThreatZ

IriusRisk is an AI threat-modeling tool for planning secure software design. It helps teams build threat models, identify threats and countermeasures, and surface vulnerabilities and compliance gaps. Its Jeff AI Assistant can turn user stories, documentation, meeting transcripts, or code into a diagram showing threats and security controls. A built-in knowledge base supports applying standards such as PCI DSS, NIST, and GDPR, marking aligned countermeasures as required. Integrations include Jira, ServiceNow, Azure DevOps, Jenkins, GitHub, OWASP ZAP, Terraform, AWS CloudFormation, and Open API; users can also import diagrams from draw.io, Visio, Lucidchart, and Microsoft Threat Modeling Tool. The free Community Edition costs nothing and allows one user and three active threat models. Enterprise has no listed price and is offered as SaaS or on-premise. IriusRisk says its cloud services are not designed or certified for certain sensitive data, including PHI and GDPR special category data.

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.
