IriusRisk Threat Modeling Platform vs Prime Security: Side-by-Side Comparison (2026)

IriusRisk Threat Modeling Platform

Product and application security teams building cloud-native architectures need IriusRisk Threat Modeling Platform to catch design-phase vulnerabilities before they reach code, which is where threat modeling actually prevents costly rewrites. The platform's automated threat generation across software architectures and supply chain risk visibility directly address NIST GV.SC, cutting the manual effort that makes most teams skip threat modeling altogether. Skip this if your organization treats threat modeling as a compliance checkbox rather than a design discipline; IriusRisk assumes you'll act on what it finds.

Prime Security

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.
