IriusRisk Threat Modeling Tool is a developer-focused threat modeling platform that enables development teams to identify and address security design flaws before code is written. The tool provides an intuitive diagramming interface for creating and verifying software security designs collaboratively. It automates the process of identifying weaknesses and potential attack vectors at the design stage of the software development lifecycle (SDLC). Key capabilities include: - A visual diagramming interface for mapping software architectures and data flows - Automated verification of software designs for security vulnerabilities - A Security Content Library containing nearly 700 components with associated threats and countermeasures - Collaborative workflows to allow multiple team members to participate in the threat modeling process - A knowledge base covering security threats and controls to support developers with limited threat modeling experience - Onboarding, training materials, and an educational workshop series to help developers build threat modeling skills The tool is positioned for integration into the development lifecycle, enabling security to be addressed proactively rather than reactively. A free tier is available, providing access to the Security Content Libraries and the full list of threats and countermeasures.
