Implement once, enforce everywhere

Replace scattered if/else permission blocks with a single Cerbos SDK call. Define access in policy, enforce it across every app, API, and AI agent - without reimplementing logic per service.

Plugs into your existing stack

Native SDKs for Go, Node, Python, Java, .NET, Rust, PHP, and Ruby and more. Integrates with your identity provider, API gateway, and CI/CD pipeline. No new infrastructure to learn.

Offload policy management

Let product owners and security teams manage roles, permissions, and tenant rules through Cerbos. You implement authorization once - they handle ongoing changes without touching code.

“What caught our attention was the deployment modes of Cerbos, which were very adherent to our new infrastructure running Kubernetes. We could choose to run as a server or as a sidecar. And it was focused on performance and easier to integrate than other solutions out there because Cerbos uses JSON or YAML; you choose.”

Update access logic without engineering sprints

Product owners update roles, permissions, and tenant-specific rules through Cerbos - no code deploys, no waiting on engineering.

Support any access model your customers need

RBAC, ABAC, PBAC, multi-tenancy, custom roles - meet enterprise buyer requirements without building from scratch.

Unblock your roadmap from IAM bottlenecks

Stop losing sprints to authorization rework. Cerbos externalizes access control from product code so your team stays focused on what matters.

“Having the separation of the permissions from the code base just makes the code base more elegant. It means they're not tied to specific endpoints. And ultimately it means that different business owners have the ability to actually make updates.”

Henry Arnold, CTO & Co-Founder, Nook

Ship policy changes through your CI/CD

Deploy authorization updates through your existing Git and CI/CD workflow. No manual steps, no separate deployment pipeline.

Full visibility into every access decision

Log requests, actions, resources, and authorization decisions across all services - human and machine.

Stay audit-ready without the fire drill

Centralized, structured logs simplify compliance cycles for SOC 2, ISO 27001, HIPAA, PCI DSS, and GDPR.

“One of our favorite features is the audit logs because they allow us to understand what's happening inside the black box. This level of visibility gives us confidence in our security posture.”

Rob Crowe, Principal Engineer

How in-house authorization becomes your bottleneck

Whether you built it from scratch or it's buried in your application code, the result is the same: scattered logic, constant rewrites, and compliance work that never ends - all for a problem that's already been solved.

You're reimplementing the same logic everywhere

Authorization checks scattered across microservices, APIs, and frontend layers. Every new surface means duplicating logic, diverging behavior, and debugging inconsistencies across services.

Every change means touching code

New tenant? New role? New feature flag? Each one requires code changes, engineering review, and a full redeployment - for what should be a configuration update.

You're responsible for auditing and compliance

Hardcoded authorization means you also own the audit trail. Building logging, evidence collection, and compliance reporting from scratch - on top of the authorization logic itself.

Your authorization headache solved

Cerbos externalizes and centralizes authorization

if (
  user.email.includes("@mycompany.com") ||
  (
    user.company.package === "premium" &&
    user.groups.includes("managers")
  )
) {
  if (user.region === resource.region) {
    // access allowed
    AuditLog.record("ALLOWED", "edit", user, resource);
  } else {
    // access denied
    AuditLog.record("DENIED", "edit", user, resource);
  }
} else {
  // access denied
  AuditLog.record("DENIED", "edit", user, resource);

Define your policies

Replace the spaghetti if/else case/switch code with a single function call.

Programmatic policy management

Create, update and manage policies using the Cerbos CLI or via API from your applications.

Flexible policy delivery

Deliver policies from from your existing Git provider, any CI/CD pipeline or directly from the Cerbos Hub interface.

Validate policy changes automatically

Run automated tests in Cerbos Hub's CI pipeline before deploying to your Policy Decision Points.

How Complex centralized scattered roles and permissions with Cerbos.

Consistency across services

Permissions managed from one place

Faster app iterations

“It used to be that somebody on the product team goes to change something, and we forgot to change it in 9 of 10 places. So it was always a disaster. With Cerbos, we have one repo of policies. That's all you have to worry about.”

Cerbos Hub

Policy Administration Point

Cerbos Hub is the control plane for policy authoring, testing, versioning, distribution, and audit visibility. Hub provides end-to-end policy management out of the box.

Data and Integration

Cerbos Synapse

Enrichment and Orchestration

Synapse fetches identity, resource, and relationship data from external systems to enrich authorization requests, and translates infrastructure protocols into Cerbos policy checks.

Cerbos PDP

Policy Decision Point

PDP is an open source authorization engine that evaluates requests against policies and returns access decisions. It's stateless, high-performance, and built to scale horizontally.

Native SDKs

Cerbos PEP SDKs

Policy Enforcement Point

Cerbos PEPs are language-native client libraries that connect applications directly to PDPs to enforce real-time access decisions, with SDKs available for all major languages.

Implement authorization once, scale everywhere

Define access in policy, enforce it with one SDK call, and let product and security teams manage changes through Cerbos - without touching your code.

Replace scattered if/else permission blocks with a single Cerbos SDK call. Define access rules in declarative policy, reusable across every service, tenant, and environment. You implement authorization once - Cerbos handles the rest.
