Description This article explains the change that needs to be made on the FortiGate for communication towards Microsoft Intune using the ISDB objects.
Scope FortiGate ISDB objects.
Solution

Microsoft has announced that the network service endpoints for Microsoft Intune will use Azure Front Door IP addresses from December 2nd of 2025. Currently, FortiGate has an ISDB object 'Microsoft-Intune' which can be used in policy to control the communication towards Microsoft Intune services.

After the changes in Microsoft, ISDB in FortiGate must also track the new Azure Front Door ranges with the 'AzureFrontDoor.MicrosoftSecurity' tag. A new ISDB object 'Microsoft-Azure.Front.Door.MicrosoftSecurity' is created to cover the IP ranges under the service tag 'AzureFrontDoor.MicrosoftSecurity'.

The administrator needs to add the newly created ISDB object 'Microsoft-Azure.Front.Door.MicrosoftSecurity', along with the ISDB object 'Microsoft-Intune', in the security policy, to control the communication towards Microsoft Intune. 

The ISDB object 'Microsoft-Azure.Front.Door.MicrosoftSecurity' is available only in FortiOS version 7.2 onwards. 

 

config firewall internet-service-name
    edit "Microsoft-Intune"
        set internet-service-id 327886
    next
    edit "Microsoft-Azure.Front.Door.MicrosoftSecurity"
        set internet-service-id 328080
    next
end
