Microsoft Defender for Endpoint

Defender for Endpoint is a fleet-security decision rather than a replacement name for the antivirus setting on one home PC. Its organizational product page describes multiplatform detection and response. Map the devices to be onboarded and identify who will investigate alerts before choosing a deployment. A useful evaluation follows an alert through investigation and the permitted response. Keep those responsibilities clear alongside the Microsoft services already managing the devices.

Microsoft's data-storage guide for Endpoint Plans 1 and 2 and Defender for Business lists file, process, registry, network and device data collected into the customer's tenant. It describes 180-day portal retention and 30-day advanced-hunting query access. Inventory data has separate expiry rules. Plan investigation and export needs around those different windows rather than assuming every view preserves the same history.
