About this tag
Endpoint security discussions on WindowsForum.com cover Microsoft Defender for Endpoint, Attack Surface Reduction (ASR) governance, and the transition from manual Automated Investigation and Response (AIR) to full scans by September 2026. Topics include reconciling ASR rule GUIDs across Intune, Configuration Manager, and Group Policy to prevent drift, as well as the impact of Windows 10 Extended Security Updates (ESU) through October 2027. Other threads examine phishing campaigns targeting Signal backup keys, smart TV proxy SDKs, and the security implications of aging hardware like prison tablets running Windows 10. Microsoft's Defender and Purview add-ons for Business Premium bring enterprise-grade endpoint protection to SMBs, while Intune updates emphasize continuous endpoint operations through auto-updates and privilege management.
