# Multi-tenant SaaS authorization that scales with your customers

Enforce tenant isolation, support custom roles per customer, and audit every access decision across your entire SaaS platform.

## Tenant-aware authorization for every customer

### Tenant isolation without code complexity

Enforce strict tenant boundaries at the authorization layer, not in application code. Each tenant operates in their own secure environment.

- Scope policies by tenant ID to guarantee data isolation across your platform.
- Separate tenant-specific logic from core policies for safer, independent changes.
- Support hierarchical organizations with teams, departments, and custom role structures.
- Scale to thousands of tenants without degrading authorization performance.

### Self-service permissions for enterprise customers

Unlock enterprise contracts by allowing customers to define their own roles and permissions without engineering involvement.

- Let tenants configure custom roles and access rules via API-driven Policy Stores.
- Build internal tools or customer portals that push tenant policy updates securely.
- Combine static base policies with dynamic tenant rules in a single versioned deployment.
- Deploy policy changes instantly without restarting services or redeploying application code.

### Audit trails with full tenant traceability

Complete visibility into tenant-specific access decisions for compliance, debugging, and customer accountability.

- View active policies and version history for each tenant directly in Cerbos Hub.
- Trace every authorization decision back to the exact policy version that enforced it.
- Maintain structured, centralized logs to simplify audits and meet enterprise compliance requirements.

## Implement tenant authorization in four steps

1. **Define tenant boundaries in policy** — Use scoped policies to isolate tenant data and enforce that users can only access resources within their own tenant.
2. **Enable self-service roles per tenant** — Let tenants define their own roles and permissions through Policy Stores, without touching your core codebase.
3. **Deploy tenant policies dynamically** — Push tenant-specific policy updates via API, Git, or CLI. Cerbos Hub validates, builds, and distributes automatically.
4. **Audit every tenant decision** — Trace every authorization decision back to the exact policy version and tenant context that enforced it.
