About this tag
Device Guard is a Windows security feature that uses virtualization-based security (VBS) to isolate critical system processes and protect against advanced threats. Discussions on WindowsForum.com cover Device Guard in the context of enterprise security, including its role in hardening endpoints against privilege escalation attacks like CVE-2026-21223, which targets the Microsoft Edge Elevation Service. IT administrators also explore scaling VBS for hotpatch readiness, where Device Guard is a prerequisite for enabling reboot-free security updates across fleets. Additional threads touch on Device Guard integration with Windows Defender ATP and its inclusion in the Windows 10 Fall Creators Update security stack. These conversations emphasize Device Guard as a core component of modern Windows defense, requiring careful planning for deployment and compatibility.
