About this tag
The network access control tag covers practical links between endpoint security posture and connectivity decisions. Recent discussions examine how Portnox Cloud can use Microsoft Defender device risk and Intune Mobile Threat Defense status to block, quarantine, or restrict access for devices that fall below policy. Other coverage focuses on Windows 11 feature updates and the need to validate wired 802.1X Network Access Control gates before broad deployment. That testing includes machine certificate authentication, DOT3SVC behavior, policy state, VLAN assignment, DHCP, and recovery procedures, especially where upgrades may disrupt wired authentication on managed hardware.
