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.

网络访问控制(NAC)的作用是限制对网络的访问,只允许注册的终端和认证的用户访问网络。然而NAC不是一个完整的LAN安全解决方案,另外还要实现主动的和被动的安全手段。Nevis是第一个也是仅有的全面的LAN安全解决方案,它以10Gbps的速率对每一个分组进行深度的安全处理,在提供高级别安全的同时能保证网络应用的可利用性和适当的性能。Nevis集成了NAC作为LAN的第一道安全防线。此外,企业还需要实现基于角色的网络访问控制,以及起关键作用的主动安全测试——实时的多级安全威胁检测和微秒级的安全威胁堵截。集中的安全策略配置、管理和报告使其能够迅速地对问题进行分析,对用户的活动进行跟踪,这些都是实时可见的,也是历史可查的。
