Microsoft has enhanced its Defender deployment tool for Windows to streamline the onboarding process for device security management. The tool now features improved progress visibility and additional administrative controls, consolidating onboarding files into a single downloadable .exe file for both modern and legacy systems. It supports silent and non-interactive options for large-scale deployments, integrates with Group Policy or Configuration Manager, and allows for custom package identifiers. Administrators can monitor deployment events through the device timeline and advanced hunting tabs for real-time insights. The updated tool is accessible via Settings > Endpoints > Onboarding > Windows and extends support to Linux. Comprehensive onboarding and offboarding guides are available on the Defender portal.
