Enforcing repository management policies in your enterprise

About policies for repository management in your enterprise

You can enforce policies to control how members of your enterprise on GitHub AE manage repositories. You can also allow organization owners to manage policies for repository management. For more information, see "Creating and managing repositories and "Organizations and teams documentation."

Configuring the default visibility of new repositories

Each time someone creates a new repository within your enterprise, that person must choose a visibility for the repository. When you configure a default visibility setting for the enterprise, you choose which visibility is selected by default. For more information on repository visibility, see "About repositories."

If an enterprise owner disallows members from creating certain types of repositories, members will not be able to create that type of repository even if the visibility setting defaults to that type. For more information, see "Enforcing a policy for repository creation."

1. In the top-right corner of GitHub AE, click your profile photo, then click Enterprise settings.

   

2. In the enterprise account sidebar, click Policies.

3. Under Policies, click Options.

4. Under "Default repository visibility", use the drop-down menu and select a default visibility.

   Warning: If you add an image attachment to a pull request or issue comment, anyone can view the anonymized image URL without authentication. To prevent unauthorized access to image URLs on GitHub AE, consider restricting network traffic to your enterprise. For more information, see "Restricting network traffic to your enterprise with an IP allow list."
