    Title = 'Unknown and unmanaged device exposure'
    Description = 'Classifies every device (corporate, BYOD, shared, kiosk, PAW, unknown) and measures the share of active devices that are unknown or unmanaged.'
    Rationale = 'Unmanaged endpoints carry no compliance signal and no endpoint protection; a large unmanaged share means Conditional Access device controls protect only part of the estate.'

    Remediation = 'Enrol or register unknown devices, retire stale device objects, and require device signals through Conditional Access so unmanaged access is the exception.'
