A council briefing claims XDR is 'just antivirus on each PC.' What correction best describes Microsoft Defender XDR at fundamentals depth?
Select an answer to reveal the explanation.
Short Explanation
Antivirus on one box is a smoke detector in one room. XDR is the whole-building alarm panel — correlating email, identity, endpoint, and app signals together. It is not Entra ID, a SharePoint template pack, or a network firewall SKU.
Full Explanation
Microsoft Defender XDR emphasizes extended detection and response with correlation across Defender domains, which is broader than a single local antivirus agent. It is not an identity directory replacement, a SharePoint template gallery, or an Azure Firewall product. Fundamentals teaching contrasts XDR correlation with single-endpoint AV thinking.
