# Overview of Air Gap

Overview and requirements for Air Gap for OneSite Patch.

Air Gap for OneSite Patch is an add-on that allows you to distribute content to devices in highly secure, network isolated (air gap) environments.

![Air Gap server diagram](https://2503798551-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F7VJNM00p5XQ4pMWqCu8y%2Fuploads%2Fgit-blob-66b854a08f249283e8e9d05523a11c9ae1e6f1c1%2Fair-gapped-server.png?alt=media)

This solution allows you to manually sync one or more network-isolated Air Gap servers with your online OneSite Patch server and populate metadata feed updates, patches and installers. The Air Gap server maintains a device and software inventory of your isolated network environment and generates a request for content from your online Patch server. You then physically convey the request to your online Patch server, which downloads relevant content and compiles a payload. This payload is physically conveyed back to your Air Gap server(s) for distribution to clients.

## Requirements

The Air Gap server is designed to be used in highly secure environments, and therefore, only works with the Adaptiva on-premises solution. It is not available in our SaaS product. Currently, we only support Windows OS and 3rd party applications for patch deployment.

You will need a physical drive or media to transport the request files (.txt) and payload files (.zip) between the online and Air Gap servers. The patch request text files can be printed and manually entered into the online Patch server if required.

### Licensing

Each server must [install the OneSite Platform](https://docs.adaptiva.com/platform-install/server-install/install-platform) and then license **OneSite Patch** and the **Air Gap for OneSite Patch** add-on. Note that the OneSite Platform build versions must be the same on both servers.

### Permissions

The configuration of the servers must be done by a Super Admin on each server (you can configure this user during installation).

## Zones

The OneSite platform supports multiple Air Gap environments as "zones", all maintained by your online Patch server. This allows you to administer separate secure environments from a single management interface.
