Mirror Security is a commercial ai spm tool by Mirror Security. Witness AI for Developers is a commercial ai spm tool by WitnessAI. Compare features, ratings, integrations, and community reviews side by side to find the best ai spm 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:
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.
Development teams shipping code through AI assistants need Witness AI for Developers to stop proprietary code leaks and prompt injection attacks before they reach production. The platform operates at the network level without SDK requirements, meaning you catch threats across GitHub Copilot, Cursor, and custom agents without forcing developers through friction-heavy integrations. Skip this if your primary concern is post-deployment LLM monitoring; Witness AI prioritizes real-time prevention during the coding phase, not compliance audits of model outputs downstream.
