Self-managed GitLab customers and administrators are responsible for the security of their underlying hosts, and for keeping GitLab itself up to date. It is important to [regularly patch GitLab](../policy/maintenance.md), patch your operating system and its software, and harden your hosts in accordance with vendor guidance.
