Enabling Dependabot for your enterprise

You can allow users of GitHub Enterprise Serverインスタンス to find and fix vulnerabilities in code dependencies by enabling Dependabotアラート and Dependabot updates.

Enterprise owners can enable Dependabot.

About Dependabot for GitHub Enterprise Server

Dependabot helps users of GitHub Enterprise Serverインスタンス find and fix vulnerabilities in their dependencies. You can enable Dependabotアラート to notify users about vulnerable dependencies and Dependabot updates to fix the vulnerabilities and keep dependencies updated to the latest version.


With Dependabotアラート, GitHub identifies insecure dependencies in repositories and creates alerts on GitHub Enterprise Serverインスタンス, using data from the GitHub Advisory Database and the dependency graph service.

We add advisories to the GitHub Advisory Database from the following sources:

After you enable Dependabotアラート for your enterprise, vulnerability data is synced from the GitHub Advisory Database to your instance once every hour. Only GitHub-reviewed advisories are synchronized. For more information about advisory data, see "Browsing security advisories in the GitHub Advisory Database" in the documentation.

また、脆弱性データはいつでも手動で同期することができます。 For more information, see "Viewing the vulnerability data for your enterprise."

Note: When you enable Dependabotアラート, no code or information about code from GitHub Enterprise Serverインスタンス is uploaded to

When GitHub Enterprise Serverインスタンス receives information about a vulnerability, it identifies repositories in GitHub Enterprise Serverインスタンス that use the affected version of the dependency and generates Dependabotアラート. You can choose whether or not to notify users automatically about new Dependabotアラート.

For repositories with Dependabotアラート enabled, scanning is triggered on any push to the default branch that contains a manifest file or lock file. Additionally, when a new vulnerability record is added to GitHub Enterprise Serverインスタンス, GitHub Enterprise Server scans all existing repositories on GitHub Enterprise Serverインスタンス and generates alerts for any repository that is vulnerable. 詳しい情報については、「Dependabotアラート について」を参照してください。

Dependabot updatesについて

Note: Dependabot security and version updates are currently in private beta and subject to change. Please contact your account management team for instructions on enabling Dependabot updates.

After you enable Dependabotアラート, you can choose to enable Dependabot updates. When Dependabot updates are enabled for GitHub Enterprise Serverインスタンス, users can configure repositories so that their dependencies are updated and kept secure automatically.

Note: Dependabot updates on GitHub Enterprise Server requires GitHub Actions with self-hosted runners.

By default, GitHub Actions runners used by Dependabot need access to the internet, to download updated packages from upstream package managers. For Dependabot updates powered by GitHub Connect, internet access provides your runners with a token that allows access to dependencies and advisories hosted on

With Dependabot updates, GitHub automatically creates pull requests to update dependencies in two ways.

  • Dependabotバージョンアップデート: Users add a Dependabot configuration file to the repository to enable Dependabot to create pull requests when a new version of a tracked dependency is released. 詳しい情報については「Dependabotバージョンアップデートについて」を参照してください。
  • Dependabotセキュリティアップデート: Users toggle a repository setting to enable Dependabot to create pull requests when GitHub detects a vulnerability in one of the dependencies of the dependency graph for the repository. For more information, see "About Dependabotアラート" and "About Dependabotセキュリティアップデート."

Dependabotアラート の有効化

Before you can enable Dependabotアラート:

  1. GitHub Enterprise Serverの右上で、プロフィール写真をクリックし、続いてEnterprise settings(Enterpriseの設定)をクリックしてください。 GitHub Enterprise Serverのプロフィール写真のドロップダウンメニュー内の"Enterprise settings"

  2. In the enterprise account sidebar, click GitHub Connect. GitHub Connect tab in the enterprise account sidebar

  3. Under "Repositories can be scanned for vulnerabilities", select the drop-down menu and click Enabled without notifications. Optionally, to enable alerts with notifications, click Enabled with notifications. 脆弱性に対するリポジトリのスキャンを有効化するドロップダウンメニュー

    Tip: We recommend configuring Dependabotアラート without notifications for the first few days to avoid an overload of emails. 数日後、通知を有効化すれば、通常どおり Dependabotアラート を受信できます。

When you enable Dependabotアラート, you should consider also setting up GitHub Actions for Dependabotセキュリティアップデート. This feature allows developers to fix vulnerabilities in their dependencies. For more information, see "Managing self-hosted runners for Dependabot updates on your enterprise."

If you need enhanced security, we recommend configuring Dependabot to use private registries. For more information, see "Managing encrypted secrets for Dependabot."
