CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Mid-market and enterprise security teams deploying AI agents across multiple environments need Operant MCP Gateway because it's the only gateway that maps MCP tool risks before they execute, not after compromise occurs. The platform covers eight NIST CSF 2.0 functions including asset discovery, continuous monitoring, and access control, with particular strength in detecting tool poisoning and non-human identity abuse that traditional API gateways miss entirely. Skip this if your AI infrastructure is still single-tenant or you're not yet managing dozens of autonomous agents; the value scales with MCP ecosystem complexity, not with simple LLM chatbot deployments.
Teams deploying AI coding agents at scale need visibility into what those models are actually doing, and Oso is built specifically for that job rather than retrofitting general security tools. It covers the full cycle: PR.AA controls around agent access, DE.CM continuous monitoring of agent behavior, and RS.AN incident analysis when things go wrong. Skip this if your AI footprint is experimental or single-use; Oso assumes you're running agents in production where audit trails and control enforcement matter.
