When enabled with wireless security features, as is the case with its NGX model, the product supports a number of security protocols, such as 802.1X, IPsec over WLAN, RADIUS, WPA2/802.11i and WEP authentication, in addition to MAC address filtering. A recently added option can require users to authenticate to a RADIUS server, aiding proper identity and access management. Its integrated unified threat management (UTM), firewall, VPN, intrusion prevention (IPS) and antivirus offer a comprehensive set of protection services for 802.11b and 802.11g wireless devices.
