Belden NAC
St. Louis, Missouri, USA
What it is
Belden NAC provides network visibility, device authentication, and granular access control for critical IT and OT networks. Its overview presents graphical reports and topology, identifies endpoints, and detects deviations from expected status. An integrated RADIUS server supports 802.1X authentication using MAC addresses, credentials, or certificates, with connections 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 collects endpoint and network measurements to identify devices and incidents such as ARP or MAC spoofing. The product is available as a physical or virtual appliance for VMware, Nutanix AHV, Proxmox, and Hyper-V, without requiring customers to provide or maintain an operating system. It supports wired, wireless, and VPN access control. Pricing is available on request, with packages, add-ons, and smaller-company tiers.
