# Introduction

{% hint style="info" %}
**Public preview**: The Marketplace app is available to select accounts. Contact your Immuta representative for details.
{% endhint %}

The Immuta Data Marketplace was built from the ground up with security and provisioning of access in mind. It allows for the following actions:

* The delegation of [data product managers](user-types#data-product-managers) to publish and manage [data products](share-data-products/reference-guides/data-products) on the Marketplace app.
* Data consumers can quickly discover and [request access](access-data-products/how-to-guides/requesting-access-to-a-data-product) to published data products in the Marketplace app.
* The delegation of data stewards to [receive requests](../review-access-requests/how-to-guides/view-and-respond-to-access-requests#view-access-requests) for access and [make determinations on them](../review-access-requests/how-to-guides/view-and-respond-to-access-requests#respond-to-an-access-request).
* Approvals have a direct impact on access. Once a user is approved, access is [auto-provisioned](review-access-requests/reference-guides/understanding-access-provisioning-and-underlying-policies-in-immuta) in the underlying data platform using powerful access policy management features.
* [Personalization of the Data Marketplace](share-data-products/how-to-guides/customize-the-marketplace-branding) with your brand's logo and colors to give it your own look and feel.

## Why use the Immuta Data Marketplace?

### Supported use cases

1. You have a concept of data products that need to be exposed to your internal lines of business for broader consumption.
2. You want data consumers to [request access to data products](access-data-products/how-to-guides/requesting-access-to-a-data-product), not database roles, which is far more intuitive.
3. Your data products can be accessed from [multiple different data platforms](../configuration/integrations).
4. You want the option for data stewards to [approve (or deny) access](../review-access-requests/how-to-guides/view-and-respond-to-access-requests#respond-to-an-access-request).
5. You want the option to approve access for a [set period of time](../access-data-products/reference-guide/data-product-access#temporary-approvals).
6. You want approvers to have [additional details](../share-data-products/reference-guides/data-products#data-stewards) about the request so they can make the correct determination.
7. You want approvals to automatically [provision access](review-access-requests/reference-guides/understanding-access-provisioning-and-underlying-policies-in-immuta) natively in the data platform.
8. You want the provisioning of approvals to be [represented as scalable policies](review-access-requests/reference-guides/understanding-access-provisioning-and-underlying-policies-in-immuta) instead of one-user-at-a-time grants.
9. You already have tools in place to do some of the above, but want to [streamline provisioning of access using the Marketplace APIs](../developer-guides/api-intro/marketplace-api/marketplace-api-endpoints).

### When you should not use the Immuta Data Marketplace

1. You are trying to share and/or monetize data **externally** (unless you own the data platform those external consumers leverage to query the data).
2. You want to automate access completely, doing away with manual approvals. You can accomplish this using data governance policies in the [Governance app](../governance/getting-started-with-secure).

## Immuta Data Marketplace architecture

The Immuta Data Marketplace is a separate experience from the existing Immuta [Governance app](../governance/getting-started-with-secure), but some actions to set up the Marketplace app must be completed in the Governance app.

### Governance app

* Register tables, views, or files as data sources.
* Manage birthright policies with global [subscription](../governance/secure-your-data/authoring-policies-in-secure/section-contents) and [data policies](../governance/secure-your-data/authoring-policies-in-secure/data-policies). Birthright policies are policies that are pre-computed through rules and do not require manual approvals.
* View reports and monitor Immuta activity and user query activity.
* [Discover](../configuration/tags/data-discovery) and tag data automatically.
* Configure data [domains](../configuration/domains/domains) and permission users to be [data product managers](user-types#data-product-managers), allowing them to publish data products from that domain.
* [Customize the branding](share-data-products/how-to-guides/customize-the-marketplace-branding) of the Marketplace app.

### Marketplace app

* [Data product managers](user-types#data-product-managers) manage and publish data products (from their assigned domains).
* [Data stewards](user-types#data-stewards) receive and process access requests to data products.
* Data consumers discover and [request access](access-data-products/how-to-guides/requesting-access-to-a-data-product) to data products.
