Cerbos

Decouple authorization management from your core code using the stateless Cerbos solution. Focus on delivering exceptional products, not maintaining the authorization infrastructure.

shield

Fine-grained access control with RBAC, ABAC, and beyond

Context-aware role definitions and attribute-based access control. Implement adaptable, granular security policies that exceed standard role-based access control.

shield

Streamline access policy management

Implement and update authorization policies in human-readable configuration. Improve visibility, collaboration and security.

shield

Permissions aware data filtering

Query for and only fetch the objects a principal has permissions to. Generate a dynamic set of conditions to filter based on access policy.

shield

Stateless and scalable

Stateless decision points that run inside your environment or at the edge (powered by WebAssembly) allow virtually unlimited scale.

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"

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!"

Decouple authorization logic from your application code

#1

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
}

#2

#3

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
}
