@David Thanks for posting in our Q&A.
For this issue, the data in Graph detectedApps is the same in discovered apps in intune portal. For intune discovered apps, I will share some information with you:
- Make sure the ownership of the devices in Intune are marked as Corporate, if it's Personal, only managed apps can be listed in the report.
- For corporate Windows 10 devices, it will lists modern apps and MSI installed apps.
Referenece:https://learn.microsoft.com/en-us/mem/intune/apps/app-discovered-apps
It means not all apps will list in discovered apps. Based on my understanding, Windows Defender may not be the appropriate app type.
Thanks for understanding.
