In today\u2019s cybersecurity landscape, threat modeling tools play a crucial role in identifying and mitigating cybersecurity threats early in the software development lifecycle (SDLC). Whether you’re working on medical device cybersecurity<\/strong><\/a> (FDA, AAMI TIR57), automotive cybersecurity (ISO\/SAE 21434)<\/strong><\/a>, or industrial security (IEC 62443), choosing the right tool can streamline cybersecurity risk management and ensure compliance with industry standards.<\/p>\n

In this line of work, it is important that manufacturers carry out regular threat analysis to determine which threats exist for their products. It goes without saying that such a threat analysis is time-consuming and requires experienced resources. And even the best threat analysis is of no use if you cannot find solutions to mitigate possible cybersecurity threats.<\/p>\n

Nowadays, several tools exist to assist organizations in identifying potential threats, mitigating risks, and ensuring automotive systems\u2019 and medical devices\u2019 compliance with industry standards. In this blog, we compare IriusRisk<\/strong> vs Microsoft Threat Modeling Tool (TMT)<\/strong> vs OWASP Threat Dragon<\/strong>, three popular threat modeling software solutions. We\u2019ll explore their features, strengths, and how they align with your team\u2019s objectives and skills, helping you select the best option for your organization’s cybersecurity threat modeling needs.<\/p>\n

IriusRisk: Compliance-Driven & Automated Threat Modeling<\/h2>\n

IriusRisk is an enterprise-level threat modeling tool that automates security-by-design principles. IriusRisk incorporates rule-based threat libraries and comes with an extensive threat and control database. The user has also the possibility to customize their own threat library. IriusRisk is compliance-driven and supports various cybersecurity frameworks like ISO 27001, NIST, OWASP, ASVS and IEC 62443. Also, the STRIDE framework, which is described in the FDA\u2019s Playbook for Threat Modeling<\/a>, is supported.<\/p>\n

The big advantage of IriusRisk is that it can be used by non-cybersecurity experts as it assigns risk scores to threats and also suggests mitigations. Of course, the assigned risk scores need to be reviewed and compared to the company\u2019s risk policy, but the initial scoring can help prioritize the threats effectively. IriusRisk automatically generates diagrams and reports, making it easier for teams to communicate risks to stakeholders.<\/p>\n

IriusRisk can be integrated in DevSecOps pipelines and tools like Jira, Jenkins and GitHub. Therefore, the cybersecurity analysis starts at an early point in development without causing too much overhead.<\/p>\n

IriusRisk is a commercial tool with enterprise pricing. However, there is a free version of IriusRisk available that already provides a lot of the useful functionality.<\/p>\n<\/div><\/div><\/div>

Microsoft Threat Modeling Tool: A Structured STRIDE-Based Approach for Developers<\/h2>\n

Microsoft Threat Modeling Tool (TMT) is a free and STRIDE-based tool designed to help developers and security teams identify, analyze, and mitigate cybersecurity threats during the software design phase. It uses predefined threat libraries to identify common vulnerabilities.<\/p>\n

The cybersecurity threats analysis (as with IriusRisk) is based on data flow diagrams (DFD). The diagrams can be easily created as Microsoft Threat Modeling Tool provides drag- and-drop elements. Based on the DFDs, threat modeling tool generates threats based on the STRIDE model:<\/p>\n
