AI Gateway is a commercial llm guardrails tool by NeuralTrust. Prompt Guard is a commercial llm guardrails tool by NeuralTrust. Compare features, ratings, integrations, and community reviews side by side to find the best llm guardrails fit for your security stack.
CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
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.
Teams deploying LLM applications across multiple models and endpoints need Prompt Guard primarily for its sub-10ms injection detection that won't throttle production inference; the multimodal coverage across text, images, and audio catches attack vectors most guardrails ignore entirely. The hybrid deployment model and customizable policies by application or user group let you enforce different security postures without forking your LLM infrastructure. Skip this if you're looking for post-generation output filtering or if your threat model centers on data exfiltration rather than prompt manipulation; Prompt Guard is built for injection prevention specifically, not broader LLM observability or compliance logging.
