CyCraft XecGuard is a commercial llm guardrails tool by CyCraft Technology. Promptfoo Guardrails is a commercial llm guardrails tool by Promptfoo. 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, company size fit, deployment model, 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 teams deploying multiple LLM applications will prefer Promptfoo Guardrails because the adaptive feedback loop actually reduces false positives over time instead of requiring constant manual tuning like static guardrails do. The self-improving mechanism learns from your red team findings and feeds them back into active defenses, which meaningfully shrinks alert fatigue within weeks of deployment. Skip this if you need guardrails for a single internal chatbot or lack red teaming capacity; the tool's strength compounds with scale and organized adversarial testing.
