CST VerdictShort answer
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. Startup and SMB engineering teams drowning in false positives will find Xygeni SAST's malware detection and CWE-506 threat alignment worth the switch; it catches obfuscated backdoors and supply-chain risks that generic SAST engines miss entirely. The one-click auto-remediation with pull request generation actually reduces remediation time rather than just flagging code, and IDE integration keeps scanning left where developers will use it. Skip this if your organization needs vulnerability correlation across runtime, infrastructure, and dependencies; Xygeni prioritizes source-code accuracy over breadth.
