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 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.
Enterprise security teams deploying large language models in production will find value in Zscaler SPLX because it combines runtime input guardrails with automated red teaming, catching both prompt injection attacks and drift in model behavior that traditional security tools miss. The platform maps to six NIST CSF 2.0 functions across asset discovery, continuous monitoring, and supply chain risk, with particular strength in the Adverse Event Analysis phase through real-time LLM log inspection. This tool is overkill for teams still piloting single LLM applications or those primarily concerned with third-party model risk; it's built for organizations managing agentic workflows and internal model customization at scale.
