Implement fast, flexible and scalable access control with ease

The Cerbos Policy Decision Point (PDP) provides a simple, yet powerful solution for authorization that can be up and running in minutes. Cerbos PDP helps you separate your authorization process from your core application code, making your authorization system infinitely scalable, more secure and easier to change as your application evolves.

Fast and secure

Flexible deployment models

Self-hosted, compatible with air-gapped, high security environments. Deploy with serverless functions or a sidecar model.

Near-instantaneous response times

Stateless design enabling sub-millisecond policy evaluation without having to synchronize application state or rely on slow network fan-out.

Full auditing and accountability

Compliance with ISO27001, SOC2, and HIPAA with real-time change logs. Keep track of every request and action.

Row-level authorization

Decouple data filtering requests from the code via a query plan API, managed by the same policies as application access.

Plug and play

Bring your own identity

Cerbos supports integration with any authentication provider.

Designed for full stack architectures

Cerbos PDP uses an API-first approach. Seamlessly integrate with frameworks.

SDKs for multiple languages

Including Javascript, Python, Go, Ruby, PHP, and more.

RBAC, ABAC and more

Cerbos offers context-aware role definitions and attribute-based access control.

Developer friendly

Define policies in YAML

Human readable configurations for better cross-functional collaboration and communication

Testable with GitOps

Manage, test and deploy fine-grained access control policies using a CI/CD/GitOps workflow.

Management API

Add or update policies using the Cerbos Admin API to simplify administration functions.

No vendor lock-in

As a stateless, self-hosted solution, Cerbos can run on public / private clouds, serverless platforms, or your data center

Where teams go after the open source core

The Cerbos PDP is free to run forever, with no limit on checks or environments, and nothing held back. What you take on yourself is everything else. Testing every policy change, getting it out to every running instance, and keeping a record of every decision someone will ask about later.

Writing policy

Every permission change is a pull request, so product and security wait on an engineer.

Writing policy

Product and security change policy themselves, without an engineer in the loop.

Testing

A policy mistake shows up once it is running, and you hear about it from a user who got let in or locked out.

Testing

Tests run on every commit and a broken policy never reaches production.

Keeping instances in sync

Instances drift apart, so the same request is allowed in one environment and denied in another.

Keeping instances in sync

Every running instance has the same policy within seconds, with no redeploy.

Audit trail

When someone asks who could access what, and when, the answer has to be reconstructed from logs sitting on each instance.

Audit trail

Every decision searchable in one place and traceable to the exact policy version, so security has the evidence without asking engineering for it.

Data for each decision

Every service fetches user and resource details itself, so the same lookups get built again in each one.

Data for each decision

Your app sends a user ID and the rest is fetched for you from your identity provider or database.

Note: Moving up is a configuration change, not a rewrite. Building the equivalent of the Cerbos platform around the open source core by yourself is roughly 19 engineer months. See the full comparison.

Why teams choose the Cerbos platform

Chuck Hardy company logo

"When I did an audit, I found that the cost of managing authorization and authentication in-house over the entire lifespan of the company was in the 7 figures. Cerbos saved that. Deploying Cerbos has allowed our engineers to spend their time on what really matters for our success."

"Having to modify authorization is a five-minute job now. Having to troubleshoot authorization is a five-minute job. So that has actually allowed the team to spend more time where it really matters on the platform."

"We went from one user - every role, to a world where there are many users - many roles. And the product, it relies on Cerbos to actually bring the value that we want to bring to customers. All of our customers are relying on Cerbos, by relying on the product, which is of course relying on Cerbos."

"One of our big considerations was speed. We have strict latency tolerances. When it comes to Cerbos - you can call it a hundred times during a request and it doesn't matter. It's incredibly fast."

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