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 deploying AI agents across internal tools will find Eve AI Agent Registry essential for the one thing most organizations skip: actually knowing what agents exist and what they're doing. The platform maps your agent inventory, enforces policy controls, and catches prompt injection attacks in real-time; its NIST coverage is strongest in asset management and continuous monitoring, which directly addresses the shadow AI problem most teams don't realize they have. Skip this if your agent use is still experimental or limited to third-party SaaS,Eve's value compounds only when you have enough internal AI infrastructure to worry about governance.
Mid-market and enterprise security teams deploying AI agents across multiple LLMs need Onyx Platform because it's the only control plane that catches shadow AI deployments and unapproved model usage before they become compliance violations. The natural language policy engine and real-time prompt injection blocking cover both governance (GV.PO) and continuous monitoring (DE.CM) without requiring security teams to become prompt engineers. Skip this if your organization runs fewer than three LLM integrations or if you need post-incident forensics more than active agent behavior enforcement; the session replay is solid but the tool's real strength is prevention during runtime, not reconstruction after the fact.
