Fine-grained access control in days not months

Externalized, policy-based, runtime authorization for your applications.

Join hundreds of leading companies using Cerbos

Cerbos Hub is Generally Available!

Easily implement, manage, and audit fine-grained access control

Make roles and permissions an asset, not a chore

Faster app development

Externalize authorization and prioritize your app’s core functionalities.

Leverage a plug-and-play, API-based approach, designed to integrate with your existing systems and accelerate development, saving you months of implementation time.

Flexible to changing requirements

Adapt to evolving business needs and regulatory requirements with policy-based authorization.

Centralized management which integrates into governance frameworks, enabling changes without compromising compliance.

Increased security at scale

Ensure least-privilege access across all apps and services in your architecture.

Implement fine-grained, zero trust runtime access controls to protect your data and systems from evolving threats at runtime.

Centralized management, decentralized decisioning

Define RBAC and ABAC policies in a single source of truth.

Manage, govern and audit access control from a central Policy Administration Point.

Deploy distributed Policy Decision Points (PDP) locally alongside applications and services for local decisioning at runtime

External authorization made easy in 3 steps

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

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);
}

if (await cerbos.isAllowed({ principal: user, resource, action: "edit" })) {
  // allowed
}

Before

After

Define the RBAC and ABAC rules in standardized policies, and manage policy decisions points from a central policy administration hub.

Call Cerbos API from anywhere in your stack - New requirements, new policies and conditions can be introduced without having to make a change to your core application.

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);
}

if (await cerbos.isAllowed({ principal: user, resource, action: "edit" })) {
  // allowed
}

What our users say about Cerbos

Rob, Principal Engineer
@ Utility Warehouse

"It's weird to say an outside company has our back, but Cerbos does. It's the people. It's their open-source code: it's high quality, you can read it, it does what it says on the tin"

Joe, Software Engineer
@ 9fin

"It's a good feeling being able to say yes to almost any permissioning requirement." "Cerbos is small, contained and easy to implement. It 100% delivers on the promise of abstracting away the complexity of decision making."

David, Senior Software Engineer
@ Salesroom

"We're not worried about scaling because we can easily increase our load on Cerbos. It will also be easy for us to change how we're distributing policies as we reach different points of scale."

Joe, CEO & Co-Founder
@ Nook

"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."

Chuck, Head of Engineering
@ Salesroom

"Instead of thinking of how much time Cerbos has saved us, I think about how much time it didn't cost us. It didn't cost us any time. Cerbos just works. I don't have to think about it. It's as simple as that."

Steve, Staff Engineer
@ NTWRK

"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."

Engin, Head of Product and Growth & Co-Founder
@ Debite

"If it wasn't for Cerbos, one thing is for sure - we would've launched later than we did. As a result, we would have less customers. And the maintenance part is also very important. Our technical team would be dealing with daily stuff regarding access controls, access logs. Now, we don't have to spend any time on that."

Rounak, Founding Engineer
@ CommandK

"Cerbos policy writing is quite flexible, and deploying as a unit microservice as well. Cerbos "doesn't get in the way" once integrated, that's the best part."

Romina, Tech Lead
@ Wizeline

"It is easy to implement and provides a solution for a problem that is often not properly addressed."

Henry, CTO & Co-Founder
@ Nook

"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."

Rasmus, CTO
@ Firtal

"Just discovered your embedded testing framework. This is probably the best balance between hyperfocused functionality and embedded tooling I've ever seen in an open source project. Damn, good work!"
