GitHub Advanced Security customers can now view their active committer count and the remaining number of unused committer seats on their organization or enterprise account’s Billing page. If Advanced Security is purchased for an enterprise, administrators can also view the active committer seats which are being used by other organizations within their enterprise.
If the active committer count exceeds the number of purchased committer licences, Repository Admins will no longer be able to enable Advanced Security for additional repositories and will need to purchase new Advanced Security seats or disable Advanced Security elsewhere before being allowed to proceed.
If Advanced Security is purchased for an enterprise, Enterprise Administrators can now ensure a gradual roll-out of GitHub Advanced Security by setting which organizations can enable Advanced Security (on the Settings page). Enterprise Administrators can choose to allow repositories for all organizations, specific organizations, or no organizations to enable Advanced Security.
If Advanced Security is disabled for an organization or repository, admin users will not be able to enable Advanced Security and will be informed that this is because of a policy setting for the organization.
These changes help billing administrators track their usage of Advanced Security against how many committer licences have been purchased, and enable Enterprise Administrators to manage and control the use of Advanced Security across organizations and repositories.
For more information please see documentation about GitHub Advanced Security licensing and viewing your GitHub Advanced Security usage.
This functionality is now available to GitHub Enterprise Cloud customers, and will also be part of GitHub Enterprise Server 3.1 (which is due to be released in Q2).
