GitHub has many features that help you improve and maintain the quality of your code. Some of these are included in all plans. Other security features require a GitHub Advanced Security.
There is no charge for GitHub Advanced Security on GitHub AE during the beta release.
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 "About dependency review."
Security overview - Review the security configuration and alerts for an organization and identify the repositories at greatest risk. For more information, see "About the security overview."
