Large Language Models (LLMs) are becoming integral to SaaS products for features like AI chatbots, support agents, and data analysis tools. With that comes a significant privacy risk: if not handled carefully, an LLM can ingest and remix sensitive personal data, potentially exposing private information in unexpected ways. Regulators have taken note – frameworks like GDPR, HIPAA, and PCI-DSS now expect AI systems to implement auditable, runtime controls to protect sensitive data.
