CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Enterprise security teams securing internal AI development and third-party agent deployments need Prisma AIRS because it catches prompt injection and data exfiltration risks that standard application security misses entirely. The platform covers the full AI lifecycle from model scanning through runtime protection, and its MCP threat detection addresses the emerging agent architecture risks most competitors ignore. Skip this if your organization hasn't yet deployed custom AI agents or large language models in production; Prisma AIRS solves a problem you don't have yet, and the pricing reflects enterprise scope.
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.
