You can now export your Advanced Security license data to review usage across your business. The CSV data can be downloaded at both enterprise and organization level, and contains: the organization, repository, username, and the user's most recent commit date. This data can be used to answer questions like, "which users are consuming an Advanced Security committer seat?", "which Advanced Security-enabled repos is a user contributing to?", and "how are Advanced Security licenses being consumed across orgs?".

For organizations, download the CSV on the organization billing settings page and security & analysis settings page.

The Advanced Security billing data can also be retrieved via the billing API. For organization-level data use the /orgs/{org}/settings/billing/advanced-security endpoint, and for enterprise-level data use the /enterprises/{enterprise}/settings/billing/advanced-security endpoint.

This has shipped on GitHub Enterprise Cloud and will be available on GitHub Enterprise Server 3.4.
