Note: Code scanning is in beta in GitHub Enterprise Server 2.22. For the generally available release of code scanning, upgrade to the latest release of GitHub Enterprise Server.
With code scanning, developers can quickly and automatically analyze the code in a GitHub repository to find security vulnerabilities and coding errors.
You can configure code scanning to run CodeQL analysis and third-party analysis. Code scanning also supports running analysis natively using GitHub Actions or externally using existing CI/CD infrastructure. The table below summarizes all the options available to users when you configure your GitHub Enterprise Server instance to allow code scanning using actions.

A license for GitHub Advanced Security
Code scanning enabled in the management console (see "Enabling GitHub Advanced Security for your enterprise")
A VM or container for code scanning analysis to run in.
GitHub Enterprise Server can run code scanning using a GitHub Actions workflow. First, you need to provision one or more self-hosted GitHub Actions runners in your environment. You can provision self-hosted runners at the repository, organization, or enterprise account level. For more information, see "About self-hosted runners" and "Adding self-hosted runners."
You must ensure that Git is in the PATH variable on any self-hosted runners you use to run CodeQL actions.
To run code scanning on GitHub Enterprise Server with GitHub Actions, the appropriate actions must be available locally. You can make the actions available in three ways.
- Recommended: You can use GitHub Connect to automatically download actions from GitHub.com. The machine that hosts your instance must be able to access GitHub.com. This approach ensures that you get the latest software automatically. For more information, see "Configuring GitHub Connect to sync GitHub Actions."
- If you want to use the CodeQL analysis workflow, you can sync the repository from GitHub.com to GitHub Enterprise Server, by using the CodeQL Action sync tool available at https://github.com/github/codeql-action-sync-tool. You can use this tool regardless of whether your GitHub Enterprise Server instance or your GitHub Actions runners have access to the internet, as long as you can access both your GitHub Enterprise Server instance and GitHub.com simultaneously on your computer.
- You can create a local copy of an action's repository on your server, by cloning the GitHub.com repository that contains the action. For example, if you want to use the actions for CodeQL code scanning, you can create a repository in your instance called
github/codeql-action, then clone the repository from GitHub.com, and then push that repository to your instance's
github/codeql-actionrepository. You will also need to download any of the releases from the repository on GitHub.com and upload them to your instance's
github/codeql-actionrepository as releases.
- If you want to download action workflows on demand from GitHub.com, you need to enable GitHub Connect. For more information, see "Enabling GitHub Connect."
- You'll also need to enable GitHub Actions for your GitHub Enterprise Server instance. For more information, see "Getting started with GitHub Actions for GitHub Enterprise Server."
- The next step is to configure access to actions on GitHub.com using GitHub Connect. For more information, see "Enabling automatic access to GitHub.com actions using GitHub Connect."
- Add a self-hosted runner to your repository, organization, or enterprise account. Weitere Informationen findest Du unter "selbst-gehostete Runner hinzufügen."
If you don't want to use GitHub Actions, you can run code scanning using the CodeQL runner.
The CodeQL runner is a command-line tool that you can add to your third-party CI/CD system. The tool runs CodeQL analysis on a checkout of a GitHub repository. For more information, see "Running code scanning in your CI system."
