GitHub Enterprise Server is the self-hosted version of GitHub Enterprise. It is installed on-premises or on a private cloud and provides organizations with a secure and customizable source code management and collaboration platform.

One of the key advantages of GitHub Enterprise Server is that it provides organizations with complete control over their source code and data. Organizations can choose where to store their repositories and can control who has access to them. Administrators can also customize the platform to meet specific needs, such as integrating other tools or implementing custom workflows.

GitHub Enterprise Server also offers enhanced security and compliance features. Organizations can configure their instance to meet their specific security requirements, such as using LDAP or SAML for authentication, setting up two-factor authentication, or implementing network security measures. Compliance features are also included, such as audit logs, access controls, and vulnerability scanning.
