Belden NAC vs ExtremeControl

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.

ExtremeControl centralizes network access control, visibility, and policy management for users, endpoints, and IoT devices. It supports wired, wireless, and VPN access control, including role-based access, guest access, BYOD onboarding, 802.1X, and secure IoT access through third-party networking devices. Administrators can build policies around user, time, location, vulnerability, or access type, then apply VLAN, ACL, and QoS rules. The product can share user, IP address, and location context with perimeter firewalls and coordinate endpoint isolation and remediation after alerts. Reports and alerts cover authentication, guest access, onboarding, device profiles, and endpoint health. Listed integrations include NGFW, SIEM, CMDB, internet security, and EMM/MDM tools; an open northbound API supports custom integrations. Virtual engines are documented for VMware ESX/ESXi and Microsoft Hyper-V. ExtremeControl is paid, with pricing on request based on unique MAC addresses connected within the past 24 hours; there is no free plan. An initial ExtremeCloud IQ Site Engine installation does not include an end-system license, though its generated evaluation license includes unlimited end-systems.
