Security alert will be available for both private and public repository. To get the alert you will need to enable dependency graph. Since public repositories are already enabled with dependency graph and security alert, they will get the notification by default. But, in private repositories you will need to enable them.
Once dependency graph is enabled, admin can also add someone from team to get security alert from dependency graph settings.
