Open Policy Administration Layer
</h2>

## What is OPAL?

OPAL is an administration layer for Policy Engines such as <a target="_blank" href="https://www.openpolicyagent.org/">Open Policy Agent (OPA)</a>, and <a target="_blank" href="https://github.com/permitio/cedar-agent">AWS' Cedar Agent</a> detecting changes to both policy and policy data in realtime and pushing live updates to your agents. OPAL brings open-policy up to the speed needed by live applications.

As your app's data state changes (whether it's via your APIs, DBs, git, S3 or 3rd-party SaaS services), OPAL will make sure your services are always in sync with the authorization data and policy they need (and only those they need).

Check out OPAL's main site at <a target="_blank" href="https://opal.ac">OPAL.ac</a>

## OPAL Use Cases

OPAL is the easiest way to keep your solution's authorization layer up-to-date in realtime. It aggregates policy and data from across the field and integrates them seamlessly into the authorization layer, and is microservices and cloud-native.

Here are some of the main use cases for using OPAL:
* **End-to-End [Fine-Grained Authorization](https://www.permit.io/blog/what-is-fine-grained-authorization-fga) service** that can be used with any policy language or data store
* [Google-Zanzibar](https://www.permit.io/blog/what-is-google-zanzibar) support for Policy as Code engines such as OPA and AWS Cedar
* Streamline permissions in microservice architectures using [centralized policy configuration with decentralized data](https://www.permit.io/blog/best-practices-for-implementing-hybrid-cloud-security) sources and policy engines
* Manage and automate the deployment of multiple Open Policy Agent engines in a Cloud-Native environment

OPAL  uses a client-server stateless architecture. OPAL-Servers publish policy and data updates over a lightweight (websocket) PubSub Channel, which OPAL-clients subscribe to via topics. Upon updates, each client fetches data directly (from the source) to load it into its managed Policy Engine instance.

### OPA + OPAL == 💜

While OPA (Open Policy Agent) decouples policy from code in a highly-performant and elegant way, the challenge of keeping policy agents up-to-date remains.
This is especially true in applications, where each user interaction or API call may affect access-control decisions.
OPAL runs in the background, supercharging policy agents and keeping them in sync with events in real time.

### AWS Cedar + OPAL == 💪

Cedar is a very powerful policy language, which powers AWS' AVP (Amazon Verified Permissions) - but what if you want to enjoy the power of Cedar on another cloud, locally, or on premise?
This is where [Cedar-Agent](https://github.com/permitio/cedar-agent) and OPAL come in.

This [video](https://youtu.be/tG8jrdcc7Zo) briefly explains OPAL and how it works with OPA, and a deeper dive into it at [this OWASP DevSlop talk](https://www.youtube.com/watch?v=1_Iz0tRQCH4).

## Who's Using OPAL?
OPAL is being used as the core engine of Permit.io Authorization Service and serves in production:
* \> 10,000 policy engines deployment
* \> 100,000 policy changes and data synchronizations every day
* \> 10,000,000 authorization checks every day

Besides Permit, OPAL is being used in Production in **Tesla**, **Walmart**, **The NBA**, **Intel**, **Cisco**, **Live-Oak Bank**, and thousands of other development teams and companies of all sizes.
