GitHub has many features that help you improve and maintain the quality of your code. Some of these are included in all plans, such as dependency graph and Dependabot alerts. Other security features require a license for GitHub Advanced Security to run on repositories apart from public repositories on GitHub.com.
For more information, see "About licensing for GitHub Advanced Security."
A GitHub Advanced Security license provides the following additional features:
Code scanning - Search for potential security vulnerabilities and coding errors in your code. For more information, see "About code scanning."
Secret scanning - Detect secrets, for example keys and tokens, that have been checked into the repository. For more information, see "About secret scanning."
Dependency review - Show the full impact of changes to dependencies and see details of any vulnerable versions before you merge a pull request. For more information, see "Reviewing dependency changes in a pull request."
For public repositories on GitHub.com, these features are permanently on and can only be disabled if you change the visibility of the project so that the code is no longer public.
For other repositories, once you have a license for your organization or enterprise, you can enable and disable these features at the organization or repository level. For more information, see "Managing security and analysis settings for your organization" and "Managing security and analysis settings for your repository."
If you have an enterprise account, license use for the entire enterprise is shown on your enterprise license page. For more information, see "Viewing your GitHub Advanced Security usage."
