CyCraft XecGuard is a commercial llm guardrails tool by CyCraft Technology. Lumeus Secure Vibe Coding is a commercial llm guardrails tool by Lumeus. 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, 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.
Development teams shipping code through ChatGPT and other LLMs need to stop credentials and sensitive data from leaking into AI prompts, and Lumeus Secure Vibe Coding blocks that inline while mapping which AI tools developers are actually using. The tool covers ID.AM and PR.DS strongly with shadow AI discovery and MCP server data access mapping that most LLM guardrails skip entirely. Skip this if you need post-generation code scanning or SAST integration; Lumeus focuses on input/output filtering and access control, not vulnerability detection in the generated code itself.
