Any login can see their own login name, the system logins, and the fixed server roles. To see other logins, requires ALTER ANY LOGIN, or a permission on the login. To see user-defined server roles, requires ALTER ANY SERVER ROLE, or membership in the role.

In SQL Server 2005 and later versions, the visibility of the metadata in catalog views is limited to securables that a user either owns or on which the user has been granted some permission. For more information, see Metadata Visibility Configuration.
