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 at scale need Eos Identity Security Platform because it's the only platform treating agent identity as a separate security perimeter. The tool maps AI agent access patterns and detects prompt injection plus credential theft in real time, addressing NIST PR.AA and ID.AM controls that traditional IAM platforms skip entirely. Skip this if your organization hasn't operationalized AI agents yet or if you're still evaluating whether agents belong in production; Eos assumes you've already decided they're here.
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.
