Genian NAC
South Korea
What it is
Genian NAC is network access control software from Genians, founded in 2005 and headquartered in South Korea. It evaluates a device’s identity, security posture, and connection context before applying access decisions. A Layer 2 Network Sensor provides real-time visibility into IP-enabled devices without changing network configuration. Device Platform Intelligence adds identity, business context, and vulnerability details such as CVEs. Administrators can enforce access with 802.1X RADIUS and DHCP servers, ARP enforcement, TCP reset, inline controls, or firewall and switch-port actions. Policies use more than 500 predefined conditions to group devices and quarantine or remediate non-compliant systems. BYOD and guest tools include a captive portal, compliance guidance, role-based access, and approval workflows. Hybrid deployment supports wired, wireless, VPN, and 802.1X access. A 30-day trial is listed, but no free plan.
