CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, 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.
Security and platform teams managing multiple LLM providers across agents and applications need Lunar.dev AI Gateway to enforce consistent data governance before requests leave your infrastructure; the combination of prompt sanitization, fine-grained access controls with human-in-the-loop gating, and full token-level auditing directly addresses the control gap that exists between your apps and third-party LLM APIs. The free tier lets you test rate limiting and observability without commitment, which matters when LLM spend is unpredictable. Skip this if you're looking for a single unified platform covering fine-tuning, model governance, and post-response content filtering; Lunar.dev is explicitly designed for outbound traffic management and doesn't replace model evaluation or output scanning tools.
