# Cerbos for developers

## How in-house authorization becomes your bottleneck

Whether you built it from scratch or it's buried in your application code, the result is the same: scattered logic, constant rewrites, and compliance work that never ends - all for a problem that's already been solved.

- **You're reimplementing the same logic everywhere** — Authorization checks scattered across microservices, APIs, and frontend layers. Every new surface means duplicating logic, diverging behavior, and debugging inconsistencies across services.
- **Every change means touching code** — New tenant? New role? New feature flag? Each one requires code changes, engineering review, and a full redeployment - for what should be a configuration update.
- **You're responsible for auditing and compliance** — Hardcoded authorization means you also own the audit trail. Building logging, evidence collection, and compliance reporting from scratch - on top of the authorization logic itself.

## Cerbos externalizes and centralizes authorization

End-to-end authorization across applications, infrastructure, and AI systems with a unified policy engine, data layer, and control plane.

## Cerbos Hub

Cerbos Hub is the control plane for policy authoring, testing, versioning, distribution, and audit visibility. Hub provides end-to-end policy management out of the box.

## Cerbos Synapse

Synapse fetches identity, resource, and relationship data from external systems to enrich authorization requests, and translates infrastructure protocols into Cerbos policy checks.

## Policy enforcement points

Cerbos PEPs are language-native client libraries that connect applications directly to PDPs to enforce real-time access decisions, with SDKs available for all major languages.

## Implement authorization once, scale everywhere

Define access in policy, enforce it with one SDK call, and let product and security teams manage changes through Cerbos - without touching your code.

- **One API call replaces your entire authorization layer** — Replace scattered if/else permission blocks with a single Cerbos SDK call. Define access rules in declarative policy, reusable across every service, tenant, and environment. You implement authorization once - Cerbos handles the rest.
- **Offload policy management to product and security teams** — Roles, permissions, and tenant-specific rules are managed through Cerbos - not your codebase. Product owners and security teams get direct control over access logic. You don't get pulled into every permissions change.
- **No need to build auditing or compliance magic** — Every authorization decision is logged automatically with full context - who, what, when, why. Audit trails, compliance evidence, and decision visibility come built in. You don't build it; you don't maintain it.
- **Never reimplement authorization across services** — One policy engine serves every app, API, microservice, and AI agent in your stack. Add new services without duplicating authorization logic. The same policies apply everywhere - consistently, automatically.
- **Fits your infrastructure - deploy anywhere** — Deploy in cloud, self-hosted, on-premise, or air-gapped environments. Native SDKs for every major language. Git-native policy delivery through your existing CI/CD. Cerbos plugs into your stack - you don't rearchitect around it.
