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 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."
To learn about what you need to know to plan your GitHub Advanced Security deployment at a high level, see "Overview of GitHub Advanced Security deployment."
To review the rollout phases we recommended in more detail, see "Deploying GitHub Advanced Security in your enterprise."
The site administrator must enable Advanced Security for your GitHub Enterprise Server instance before you can use these features. For more information, see "Configuring Advanced Security features.
Once your system is set up, 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."
