Implement roles and permissions in under 4 mins

Watch the Cerbos video tutorial on adding a typical CRUD policy to a simple express app in Node.

A developer-built, developer-friendly authorization service

shield

Configuration not code

Define permissions as config outside of your application logic meaning no more code changes when requirements change.

Decoupled authZ
shield

Flexible deployment options

Cerbos PDPs are self hosted, and can be deployed as a sidecar, service, or function to ensuree seamless integration with your existing infrastructure.

Deployment
shield

Developer Tooling

Ensure policies are production ready using first class support for GitOps including a built-in testing framework and CI/CD integration.

GitOps & CI/CD
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

avatar

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"

avatar

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."

avatar

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."

avatar

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."

avatar

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."

avatar

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."

avatar

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."

avatar

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."

avatar

Romina, Tech Lead
@ Wizeline

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

avatar

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."

avatar

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!"
