About this page
35 sources
A change belongs to Defender when it comes from a source about the product or one of its names (Defender, Microsoft Defender, Defender XDR, Microsoft Defender XDR), when a roadmap entry, Windows release, or known issue lists it, or when an MSRC CVE, CISA entry, or lifecycle date names it. Another product's notes and community posts that only mention Defender are listed under "Also mentioned in" and are not counted as its changes. Sources marked quiet are about Defender alone and have had nothing new for 30 days; check the source before reading silence as "no change".
