Prime Security is a commercial threat modeling tool by Prime Security. IriusRisk Threat Modeling is a commercial threat modeling tool by IriusRisk. Compare features, ratings, integrations, and community reviews side by side to find the best threat modeling fit for your security stack.
CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Startup and SMB security leaders who lack formal threat modeling processes should adopt Prime Security to catch architectural flaws before developers commit to bad designs. The tool's AI-powered automated design reviews convert abstract security risk into concrete, prioritized tasks tied to business context, collapsing what normally takes weeks of manual review into hours. Skip this if your organization already has embedded security architects running threat modeling in your development workflow; Prime Security replaces manual rigor, not supplements it.
Development teams embedding security into design cycles will get the most from IriusRisk Threat Modeling because it actually forces threat models into your existing CI/CD pipeline instead of treating them as a compliance checkbox. The platform scores high on NIST ID.RA and PR.PS, and its two-way Jira and Azure DevOps integration means threat findings land where developers already work. Skip this if your org views threat modeling as an annual architecture exercise; IriusRisk assumes continuous, collaborative modeling across product and platform teams.
