CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Enterprise and mid-market security teams building or deploying large language models need Zscaler AI-SPM because it's the only tool that maps AI risks to actual business impact rather than just flagging misconfigurations. The platform covers the full AI supply chain from training data access control through prompt injection detection and LLM output monitoring, with explicit compliance mappings to NIST AI RMF and EU AI Act requirements that auditors actually ask for. Skip this if your organization treats AI security as a footnote to your existing cloud posture program; AI-SPM assumes AI is now a primary business system worth dedicated governance.
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.
