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.
Built for modern SaaS
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.
Multi-tenancy at scale
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.
Seamless integration
Works with your existing tools, workflows, and infrastructure
Flexible policy sources
Add tenant policies from any Git provider, CI/CD tool, Cerbos Hub API, CLI, or direct UI upload.
SDKs for every stack
First-class SDKs for JS, Go, Python, Java, .NET, Rust, PHP, and Ruby.
Deployment targets
Deploy Cerbos PDPs in containers, serverless, edge, or multi-region clusters.
Compliance ready audit logs
