Features, pricing, ratings, and pros & cons — compared head-to-head.
AI Security Gateway™ is a commercial llm guardrails tool by AI Security Gateway. Zscaler AI Runtime Protection is a commercial llm guardrails tool by SPLX. Compare features, ratings, integrations, and community reviews side by side to find the best llm guardrails fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Mid-market and enterprise teams deploying LLMs at scale need Zscaler AI Runtime Protection primarily for its near-zero latency filtering of prompt injections and jailbreaks without slowing inference. The tool's real-time detection paired with full prompt and response logging addresses NIST DE.CM and DE.AE requirements that most AI security offerings skip over. Skip this if your organization runs fewer than three LLM applications in production or needs post-incident recovery capabilities; Zscaler is detection and blocking only, not forensic reconstruction.
OpenAI-compatible proxy for LLM DLP, PII redaction, and cost governance.
