How CWS works with LLM Guard
CWS helps customers evaluate, deploy, and operate LLM Guard products as part of an AI security program. Engagements span vendor selection, proof-of-concept design, integration with existing controls, day-2 operations, and exit planning if the fit changes over time.
CWS does not resell LLM Guard. The recommendation is honest, evidence-based, and tied to the customer's posture gaps, not to channel economics.
