AuthZed's Authorization Infrastructure for AI is designed to provide fine-grained permission systems for RAG pipelines and agentic AI systems, ensuring data protection, authorized actions, and compliance. It leverages SpiceDB, an open-source database inspired by Google Zanzibar, to store and compute permissions data, enabling scalable authorization controls for massive datasets. The infrastructure supports secure access control across every stage of the AI pipeline, from document ingestion to vector search to agent behavior, ensuring that sensitive customer or corporate data remains properly governed. It also addresses the authorization problem for AI by providing a better solution for teams building with LLMs, reducing the attack surface and mitigating risks such as exposure of customer records or unauthorized access to payroll data. With AuthZed's Authorization Infrastructure for AI, teams can safely scale their AI features without introducing security risks or violating data boundaries, ensuring that AI systems respect the same access controls as the rest of the system.
