Aiceberg Guardian Agent vs Onyx Platform: Side-by-Side Comparison (2026)

Aiceberg Guardian Agent

Mid-market and enterprise security teams deploying autonomous AI agents need Aiceberg Guardian Agent because it's the only tool that actually traces agent decisions back to their inputs with deterministic oversight, not just logging what happened after the fact. The millisecond-latency monitoring and patented explainable AI technology deliver the input-to-output linking that NIST DE.CM and DE.AE demand, giving you real control over LLM calls and tool execution chains before they cause damage. Skip this if your agents are simple retrieval tools or if you're still in the "let's see what happens" phase; Guardian Agent is built for teams that need to audit and justify every agent action to compliance.

Onyx Platform

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.
