Belden NAC vs Genian NAC

Belden NAC is network access control software for critical IT and OT networks, providing network visibility, device authentication, and granular access control. Its overview shows graphical reports and topology, identifies endpoints, and detects deviations from expected status. Authentication uses 802.1X through an integrated RADIUS server with MAC addresses, credentials, or certificates, and can connect to existing identity stores. VLAN Manager supports static and dynamic segmentation. Guest Service grants external devices temporary, time-limited access to defined LAN and Wi-Fi resources. Advanced Security gathers endpoint details and network measurements to detect devices and incidents such as ARP or MAC spoofing. The software is available as a physical or virtual appliance for VMware, Nutanix AHV, Proxmox, and Hyper-V; Belden says no customer-provided operating system is required. Switches and routers must be manageable through SNMP V1, V2c, or V3 with read and write access, or through SSH or Telnet. Pricing is on request. Packages combine core NAC features, with individually added add-ons and special tiers for smaller companies. A managed service option is also available.

Genian NAC evaluates device identity, posture, and connection context to decide what network access a device receives. Its Layer 2 Network Sensor detects IP-enabled devices in real time without requiring changes to existing network configuration. Device Platform Intelligence adds identity, business context, and vulnerability details, including CVEs. Access controls include 802.1X RADIUS and DHCP, ARP enforcement, TCP reset, inline enforcement, and actions through firewalls or switch ports. Policies can group devices using more than 500 predefined conditions and quarantine or remediate devices that fail requirements. BYOD and guest tools include a captive portal, self-service compliance guidance, role-based access, and approval workflows. The optional agent can manage desktop settings, applications, OS updates, peripherals, wireless connections, and scripts. Genian NAC supports wired, wireless, VPN, and 802.1X access control, and offers cloud-managed, on-premises, and service options. It runs on API, Linux, macOS, self-hosted, web, and Windows platforms. The listed offer includes a 30-day trial, but no free plan.
