NAC's (Network Access Control) role is to restrict network access to Only compliant endpoints and (66) users. However, NAC is not a complete LAN (67) solution; additional proactive and (68) security measures must be implemented. Nevis is the first and only comprehensive LAN security solution that combines deep security processing of every packet at 10Gbps, ensuring a high level of security plus application availability and performance. Nevis integrates NAC as the first line of LAN security (69). In addition to NAC, enterprises need to implement role-based network access control as well as critical proactive security measures — real-time, multilevel (70) inspection and microsecond threat containment.
