-* **Dependency review:** Enabled by default and cannot be disabled.
-* **{% data variables.product.prodname_dependabot_alerts %}:** Not enabled by default. {% data variables.product.prodname_dotcom %} detects insecure dependencies and displays information in the dependency graph, but does not generate {% data variables.product.prodname_dependabot_alerts %} by default. Repository owners or people with admin access can enable {% data variables.product.prodname_dependabot_alerts %}.
+* **Dependency graph:** Not enabled by default. Available for public and private repositories, and can be enabled or disabled by repository administrators.

+* **Dependency review:** Available when the dependency graph is enabled. For private repositories, the repository must also be owned by an organization that uses {% data variables.product.prodname_team %} or {% data variables.product.prodname_ghe_cloud %} and has a license for {% data variables.product.prodname_GHAS_or_code_security %}. For more information, see [AUTOTITLE](/get-started/learning-about-github/about-github-advanced-security) and [AUTOTITLE](/code-security/supply-chain-security/understanding-your-software-supply-chain/exploring-the-dependencies-of-a-repository#enabling-and-disabling-the-dependency-graph).
+* **{% data variables.product.prodname_dependabot_alerts %}:** Not enabled by default. Repository owners or people with admin access can enable {% data variables.product.prodname_dependabot_alerts %} for repositories that have the dependency graph enabled.
   You can also enable or disable Dependabot alerts for all repositories owned by your user account or organization. For more information, see [AUTOTITLE](/account-and-profile/setting-up-and-managing-your-personal-account-on-github/managing-personal-account-settings/managing-security-and-analysis-settings-for-your-personal-account) or [AUTOTITLE](/organizations/keeping-your-organization-secure/managing-security-settings-for-your-organization/managing-security-and-analysis-settings-for-your-organization).
