The rapid growth of data has intensified security risks for Large Language Model (LLM) use cases handling sensitive information. Thales addresses these challenges with the CipherTrust Data Security Platform, protecting data at rest, in transit, and during execution. The solution secures LLM backends, prompts, and responses, including Retrieval-Augmented Generation (RAG) workflows, using transparent encryption and strong access controls to preserve data confidentiality and integrity.
