Features, pricing, ratings, and pros & cons — compared head-to-head.
CyCraft XecGuard is a commercial llm guardrails tool by CyCraft Technology. Lunar.dev AI Gateway is a free llm guardrails tool by Lunar.dev. Compare features, ratings, integrations, and community reviews side by side to find the best llm guardrails fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Mid-market and enterprise security teams deploying internal LLM applications need XecGuard specifically because prompt injection attacks bypass traditional perimeter controls and jailbreak attempts expose proprietary system prompts; this tool blocks both in real time before an LLM ever processes malicious input. The LoRA adapter architecture means integration takes weeks not months, and CyCraft's red teaming assessment catches attack vectors your team hasn't thought to test yet. Skip this if you're still evaluating whether to use LLMs at all, or if you need guardrails that also handle output filtering and hallucination detection; XecGuard focuses the input side.
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.
