Prime Security is a commercial threat modeling tool by Prime Security. Heeler Runtime Threat Modeling is a commercial threat modeling tool by Heeler. Compare features, ratings, integrations, and community reviews side by side to find the best threat modeling fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, 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.
Heeler Runtime Threat Modeling
Development and security leaders responsible for cloud application risk want threat models that stay current with actual runtime behavior, not static diagrams built once and ignored. Heeler Runtime Threat Modeling automatically decomposes applications and regenerates threat models as your infrastructure drifts, catching material changes to APIs and components in real time; this covers ID.RA and DE.CM rigorously while most tools cover only one. Skip this if your team needs threat modeling to feed into a broader GRC platform or if you're still managing monoliths where drift detection feels premature.
