How CWS works with Promptfoo

CWS helps customers evaluate, deploy, and operate Promptfoo 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 Promptfoo. The recommendation is honest, evidence-based, and tied to the customer's posture gaps, not to channel economics.
