# API Provider & Enterprise

## Example: API Provider

An API provider uses Sestra to:

* protect endpoints
* require verified access
* avoid managing user accounts

The API only checks whether a session is active.

***

## Example: Enterprise Internal API

An enterprise uses Sestra to:

* control internal API access
* avoid storing employee identity
* enforce temporary access

Access is granted only when needed.
