LLM observability, evaluation, and prompt management.
CWS helps customers evaluate, deploy, and operate LangSmith 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.
