Based 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 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.
Mid-market and enterprise security teams drowning in unmanaged AI agents across their identity stack should start here; Silverfort AI Agent Security finds and controls what you don't know exists, which is the only real problem in this category. The platform maps agents to human owners through visual workflows and enforces least privilege through real-time MCP gateway inspection, covering NIST ID.AM and PR.AA where most identity tools go silent. Skip this if your organization has fewer than 50 employees or hasn't yet standardized on a single IdP; the discovery value collapses without scale and integration breadth.
