CST VerdictShort answer
Development teams shipping code with AI assistants need Mirror Security to prevent secrets and PII from leaking into training data and model outputs. The tool enforces access control at the developer level with encrypted vector indexing and policy-based blocking, covering PR.DS and PR.PS across the NIST CSF 2.0. Skip this if your org hasn't standardized on specific AI coding tools yet; Mirror works best when you're already committed to Copilot, Claude, or similar and need guardrails around what those tools can see. Security teams protecting AI applications in production need Protect AI Layer because it catches multi-turn attacks and RAG poisoning that static scanning misses entirely. The platform monitors 27 turnkey policies mapped to NIST and MITRE frameworks with automated remediation, covering the full detection-to-response chain that most AI security tools abandon after flagging a problem. Skip this if you're looking for pre-deployment code scanning; Protect AI Layer is runtime-only and assumes your AI app is already running.
