Client SDK Example

if cerbos_client.is_allowed("edit", user, resource, None).await? {
    // access allowed
}

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

Make use of context such as IP address and time of day to make realtime access decisions

Ultrafast API

Access decisions in milliseconds.

GitOps

Develop, test, and deploy policies just as you do with your source code.

Multiple Environments

Built-in policy versioning to support canary deployments and different environments.

Cloud Native

Containerised deployment as a microservice or a sidecar. REST and gRPC interfaces. Top-notch observability.

Audit Logs

Capture every decision and analyze them later.
