Abstract: The invention provides AI-based system and method for enforcing data-security policies during interactions with AI agents. The system includes a domain-specific, security-aware large language model (LLM) and a sensitive data anonymizer module. The LLM detects sensitive data in user prompts, which the anonymizer encrypts and replaces with encrypted placeholders, preserving the prompt's structure before sending it to the AI agent. Upon receiving a response, the system checks for undesirable content. If none is found and the response contains encrypted data, the anonymizer decrypts it to provide the final user-readable response. This ensures secure, policy-compliant communication with AI agents. The invention can ensure compliance with organizational policies while enabling seamless integration into existing LLM systems, thereby mitigating risks associated with data exposure and enhancing the security of LLM-generated responses.
