VirtueGuard is a commercial llm guardrails tool by Virtue AI. Witness Control is a commercial llm guardrails tool by WitnessAI. 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:
Teams deploying AI agents at scale need guardrails that catch prompt injections and unsafe tool calls before they execute, not after, and VirtueGuard's sub-10 millisecond ActionGuard runtime monitoring does exactly that across text, image, audio, and code without requiring model retraining. The multimodal protection and MCP vulnerability scanning address real gaps in agent security that generic LLM firewalls leave open. Skip this if your primary concern is detecting hallucinations or optimizing model output quality; VirtueGuard is purpose-built for blocking malicious inputs and preventing agent actions from breaking your security perimeter, not improving inference.
Security teams deploying ChatGPT, Copilot, and other AI tools across departments need Witness Control because it enforces policy without requiring browser extensions or per-user agents, which actually works in hybrid environments where you can't control every device. Network-level visibility combined with real-time data redaction covers four NIST CSF 2.0 areas (GV.PO, PR.DS, DE.CM, DE.AE), meaning you get policy enforcement and compliance logging in a single deployment. Skip this if your organization only needs point controls for a handful of power users or lacks the infrastructure to route traffic through a cloud gateway.
