Team: Huntress Managed Endpoint Detection and Response (EDR)
Product: Managed Microsoft Defender
Environment: Windows OS
Summary: Microsoft Defender checks for hourly updates, but is always up to date if the endpoint machine is up to date.
Managed Defender - Can I force an update? How do I know if my Microsoft Defender is up-to-date?
These are done through Windows Update and Microsoft Defender itself checks for updates, so if your machine is up-to-date, Microsoft Defender is. Microsoft Defender also checks for updates every hour.
