The GPO -> Security settings section contains a table which lists settings for which "no applicable GPO has been found". Many of the listed settings are in fact set in one or more GPOs. If it's helpful, here's the list of 13 detections with only the bottom two (bolded) being "legitimate":
Guest account
Allow anonymous SID/Name translation
Let Everyone permissions apply to anonymous users
Limit local account use of blank passwords to console logon only
Sharing and security model for local accounts
Do not store LAN Manager hash value on next password change
Do not allow anonymous enumeration of SAM accounts and shares
Do not allow anonymous enumeration of SAM accounts
LDAP client signing requirements
Refuse machine account password changes
Microsoft network server: Digitally sign communications (if client agrees)
