CST VerdictShort answer
Security teams standardizing on multiple LLM providers should use AI Gateway to stop paying for redundant API calls and enforce access controls at the model consumption layer. The semantic caching and smart routing cut token spend measurably, while the granular rate limiting and consumer group-based RBAC address the access control gaps that emerge when developers bypass your approved models. Skip this if your organization runs a single LLM internally or has already baked governance into your application layer; AI Gateway solves the hub problem, not the spoke problem. Mid-market and enterprise security teams deploying internal LLM applications need Zscaler SPLX Platform because it's the only platform that treats AI systems as supply chain risk, not just another application to monitor. The platform covers the full NIST lifecycle from ID.AM asset discovery through DE.CM runtime inspection, with native jailbreak detection and automated red teaming that catches prompt injection attacks before they reach production. Skip this if your organization hasn't yet built or integrated custom LLM applications; you're paying for capabilities you won't use for another 18 months.
