Zscaler AI Runtime Protection is a commercial ai threat detection tool by SPLX. Protect AI Layer is a commercial ai threat detection tool by Protect AI. Compare features, ratings, integrations, and community reviews side by side to find the best ai threat detection fit for your security stack.
CST VerdictBased 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.
Security teams protecting AI applications in production need Protect AI Layer because it catches multi-turn attacks and RAG poisoning that static scanning misses entirely. The platform monitors 27 turnkey policies mapped to NIST and MITRE frameworks with automated remediation, covering the full detection-to-response chain that most AI security tools abandon after flagging a problem. Skip this if you're looking for pre-deployment code scanning; Protect AI Layer is runtime-only and assumes your AI app is already running.
