About the security overview
Organizations that use GitHub Enterprise Cloud can use the security overview for a high-level view of the security status of their organization or to identify problematic repositories that require intervention. These organizations can view aggregate or repository-specific security information in the security overview. Organizations that use GitHub Enterprise Cloud can also use the security overview to see which security features are enabled for their repositories and to configure any available security features that are not currently in use. For more information, see the GitHub Enterprise Cloud documentation.
