Kindly need to know if we have devices onboarded to defender portal and not on intune, the Antivirus, Disk Encryption, EDR, Attack Surface Reduction with other features can be configured to affect them?
Devices that onboard to Microsoft Defender for Endpoint and have registered but aren't managed by Intune display Microsoft Defender for Endpoint in the Managed by column. These are the devices that can receive policy for security management for Microsoft Defender for Endpoint.
You can also find two labels for devices that are using security management for Microsoft Defender for Endpoint:
MDEJoined - Added to devices that are joined to the directory as part of this scenario. MDEManaged - Added to devices that are actively using the security management scenario. This tag is removed from the device if Defender for Endpoint stops managing the security configuration.
