Repello AI Agent Wiz is a free threat modeling tool by Repello AI. 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.
CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Security teams building AI agent systems in Python will find immediate value in Repello AI Agent Wiz because it's the only free tool that maps threat paths across the entire agent-to-tool-to-LLM chain without requiring configuration. The MAESTRO framework covers 12 documented agentic failure modes,privilege escalation, prompt confusion, ghost agents, infinite recursion,that traditional threat modeling misses entirely. Not suited for organizations running agents across multiple languages or those needing runtime enforcement rather than design-phase analysis; Repello is a pre-deployment mapping tool, not a monitoring system.
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.
