Agent Vault is a commercial agentic ai security tool by Ntur AI. Onyx Platform is a commercial agentic ai security tool by Onyx Security. Compare features, ratings, integrations, and community reviews side by side to find the best agentic ai security fit for your security stack.
CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Enterprise security teams deploying autonomous AI agents at scale need Agent Vault's cryptographically enforced tool execution and immutable audit trails, because agent-generated decisions leave traditional access controls behind. The platform's zero-trust agent-to-agent communication and post-quantum cryptography support address NIST PR.AA and PR.DS in ways purpose-built for agentic systems, not bolted onto legacy IAM. Skip this if your agents are still in sandbox testing or you're treating agentic security as a future problem; Agent Vault assumes you're already running agents in production and need forensic proof of what they did.
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.
