CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Mid-market and enterprise security teams with fragmented risk conversations across business units will see the most value in FYEO Enterprise Threat Model; it forces structured asset cataloging and threat scoping that actually sticks, rather than letting risk assessments languish in spreadsheets. The service covers all four NIST GV and ID risk management functions, meaning stakeholders get aligned on what matters before you're halfway through remediation. Skip this if your organization has already mapped critical assets and runs mature threat modeling in-house; FYEO is built for teams starting from scattered baselines, not optimizing established processes.
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.
