Build AI applications that respect data boundaries and scale to billions of documents with proven authorization infrastructure.
Every AI response respects user permissions with accurate, instant, and scalable access filtering.
Filter document retrieval before context reaches your LLM. AI responses never include information from documents the user isn't authorized to see, maintaining data boundaries at retrieval time.
Replicate permission models from Google Drive, OneDrive, SharePoint, and Box without custom code. AuthZed's flexible schema expresses any permission structure in a single unified system.
Keep authorization current as permissions change in source systems. Revocations are reflected immediately across your AI pipeline, not minutes or hours later when damage is already done.
Handle billions of documents with unique fine-grained permissions at consistent latency. Proven at OpenAI scale with 37+ billion documents, where authorization performance never becomes a pipeline bottleneck.
"We decided to buy instead of build early on. This is an authorization system with established patterns. We didn't want to reinvent the wheel when we could move fast with a proven solution."

When enterprise customers connect their data, they expect their permissions to be respected. AuthZed makes sure your AI never surfaces information users aren't authorized to see, at any scale.
Permission checks complete in single-digit milliseconds. Authorization never becomes the bottleneck in your AI pipeline. For bulk filtering, AuthZed's Materialize feature pre-computes results so queries across millions of documents return instantly, making permission-aware RAG performant at scale.
Express Google Drive's folder inheritance, OneDrive's sharing semantics, Box's collaboration rules, or your custom permission model in a single declarative schema. Add new integrations by updating the schema. No code changes, no re-architecture, no per-customer logic scattered through your codebase.
37 billion documents with fine-grained permissions. This isn't theoretical capacity. It's what AuthZed handles in production for the world's largest enterprise AI deployments, with reliability that eliminated most SRE burden for the OpenAI team.
Power AI assistants that integrate with enterprise knowledge while respecting existing permissions. Employees only see information from documents they're authorized to access, maintaining trust in AI outputs.
Build multi-tenant AI services with data isolation guarantees. Multiple customers and use cases run on shared infrastructure without compromising security boundaries or leaking training data across tenants.
Secure access to code repositories, secrets, deployments, and infrastructure with fine-grained controls. Supports the complex permission requirements of platform engineering teams building internal developer platforms.
Enforce row-level and column-level permissions across data warehouses and analytics platforms. Users query exactly the data they should see, nothing more, with performance that doesn't degrade as permission complexity grows.
Leading AI companies trust AuthZed to handle authorization at scale while maintaining data boundaries.

OpenAI securely connects enterprise knowledge with ChatGPT using AuthZed to manage fine-grained permissions across billions of documents for millions of business users.

Workday uses AuthZed Dedicated to deliver secure, scalable authorization for their AI-native contract lifecycle management platform, unifying access control across millions of documents.
