CloudMatos Prompt Firewall vs Lunar.dev AI Gateway: Side-by-Side Comparison (2026)

CloudMatos Prompt Firewall

Security teams deploying multiple LLM models across production workloads need CloudMatos Prompt Firewall to stop prompt injection and data exfiltration at inference time, not after the fact. The tool's zero-trust prompt filtering and real-time jailbreak signature detection address DE.CM and DE.AE functions that most guardrails treat as afterthoughts, while multi-model compatibility means you're not locked into OpenAI. Skip this if your LLM use is experimental or limited to a single vendor's API; the policy enforcement overhead assumes mature, compliance-driven deployments where audit trails matter as much as blocking attacks.

Lunar.dev AI Gateway

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.
