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 agentic AI should use Enkrypt AI MCP Gateway because it's the only tool that enforces policy at the point where agents actually call external tools, not after the fact. The inline proxy architecture with pre-execution evaluation and post-execution validation covers the full request-response cycle, and multi-tenant policy scoping by role and environment means you're not rebuilding rules for each deployment. Skip this if your agents are mostly isolated from sensitive systems; the approval workflow and secrets detection add friction that only pays off when agents touch production data or privileged APIs.
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.
