Best Threat Modeling Tools for GitHub

IriusRisk is an open Threat Modeling platform that can be used by any development and operations team – even those without prior security training. Whether your organization follows a framework or not, we can work with all the threat modeling methodologies, such as STRIDE, TRIKE, OCTAVE and PASTA. We support organisations in financial services, insurance, industrial automation, healthcare, private sector and more. IriusRisk is the industry's leading threat modeling and secure design solution in Application Security. With enterprise clients including Fortune 500 banks, payments, and technology providers, it empowers security and development teams to ensure applications have security built-in from the start - using its powerful threat modeling platform. Whether teams are implementing threat modeling from scratch, or scaling-up their existing operations, the IriusRisk approach results in improved speed-to-market, collaboration across security and development teams, and the avoidance of costly security flaws.

SD Elements helps AppSec teams cope with fast-growing development demands by spelling out which security controls each project needs at the design stage. It follows a Security by Design approach, meaning it looks at architecture, data use, and compliance needs early, identifies relevant risks, and turns them into concrete requirements while changes are still cheap and low-friction. Many teams see security review time drop by 30–50% and fewer late surprises before release. The platform generates project-specific requirements mapped to standards such as NIST, OWASP, PCI, and ISO, and pairs them with concise implementation guidance developers can act on. This lets small AppSec groups support security for portfolios of 100+ applications without adding headcount, while driving consistent, policy-aligned expectations across teams and products instead of ad hoc checklists. SD Elements connects to Jira, CI/CD pipelines, and other engineering tools so security work is delivered and tracked in the same systems developers already use. Traceability is a core capability: every requirement is linked to its underlying risk, relevant standards, and evidence of implementation. AppSec leaders and directors get clear views of coverage, posture, and progress across applications, making it easier to reduce risk, support audits, and report meaningful security metrics to senior leadership.

ThreatModeler™, an enterprise threat modeling platform, is an automated solution that reduces the effort required to develop secure applications. Today's information security professionals have a pressing need to create threat models of their organizations' data and software. We do this at the scale of their IT ecosystem and with the speed of innovation. ThreatModeler™, which empowers enterprise IT organizations, allows them to map their unique security requirements and policies directly into the enterprise cyber ecosystem. This provides real-time situational awareness of their threat portfolio and risks. InfoSec executives and CISOs gain a complete understanding of their entire attack landscape, defense-in depth strategy, and compensating control, which allows them to strategically allocate resources and scale up their output.
