CST VerdictShort answer
Enterprise security and AI teams deploying agents on regulated datasets will see immediate value in Confidential Agents' hardware-level encryption during inference, which eliminates the typical choice between data utility and privacy. The platform covers NIST PR.DS and PR.AA controls with cryptographic verification built in, meaning you get attestable proof of data isolation rather than policy assertions. Skip this if your use case is consumer-scale or doesn't involve cross-organizational data sharing; the operational overhead and pricing model assume you're solving a specific high-stakes problem, not running commodity AI workloads. 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.
