IriusRisk is a threat modeling platform designed to help engineering and development teams identify security design flaws early in the software development lifecycle — before code is written. The platform automatically generates threat models based on an organization's internal security policies, producing a list of recommended and required countermeasures. These are derived from a library of nearly 700 components, each mapped to known threats and mitigations. Unlike SAST and DAST tools that scan code for bugs, IriusRisk focuses on architectural and design-level vulnerabilities — the category of flaws that code scanning tools cannot detect, which the company estimates accounts for up to 50% of application vulnerabilities. Security tasks generated by IriusRisk can be pushed directly to issue trackers such as Jira and Microsoft TFS/Azure DevOps, allowing development teams to address security requirements within their existing workflows. The platform does not require users to have formal security training. The built-in threats and countermeasures libraries are designed to guide and inform development teams about applicable threats and appropriate mitigations for their specific technology stack. A free tier is available, providing access to the Security Content Libraries, component catalog, and full threats and countermeasures content.
