CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Organizations deploying multiple LLM applications will see immediate value in Akamai Firewall for AI because it enforces consistent security policy across any model or vendor without requiring integration rewrites. The model-agnostic architecture and real-time monitoring against prompt injection, jailbreaks, and data exfiltration address the compliance gap most teams face when LLMs touch sensitive data. Skip this if your use case is a single, narrowly scoped chatbot with no access to customer information; the policy overhead won't justify the spend.
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.
