Businesses NCS - SIS KG340_345 ImageNSA-certified, Innovative government-grade encryption from Raytheon delivers the lowest cost of ownership, enhanced performance, and scalability for Ethernet networks

The demand for network bandwidth has increased dramatically with the need to provide realtime situational awareness and analytical capabilities. This highly sensitive information and infrastructure must be protected. Agencies are connecting to worldwide locations with multigigabit lines at a fraction of the cost that they were paying before. To meet this growing need, agencies are looking for more capacity, finer granularity, and more efficient ways to use existing bandwidth to encrypt both classified and sensitive data.

Why Ethernet?

The requirement for real-time information sharing is driving agencies to eliminate stovepipes and build converged network infrastructures to provide a common operating environment. Ethernet transport technology is being deployed worldwide to efficiently carry data over wide area networks (WANs) that connect regional commands, domestic and international facilities, data centers, and disaster recovery sites. Aligning encryption capabilities with the transport technology can provide substantial benefits to the organization. Unlike traditional solutions that encrypt at Layer 3, Ethernet encrypts at Layer 2, thus minimizing cost, improving performance of the network, and enterprise scalability.


Reduced Cost

Ethernet encryption dramatically reduces the burden of network security and lowers total cost of ownership by simplifying the network architecture, streamlining security policy management, and eliminating the inefficiencies associated with conventional Layer 3 security management.

Maximum Performance

At the protocol level, Ethernet encryption maximizes performance over traditional Layer 3 encryption solutions. Efficiencies are achieved through reduced protocol overhead, eliminating GRE encapsulation for multicast and MPLS environments. In addition, its microsecond latency provides the necessary performance needed for real-time applications. With Ethernet, scarce bandwidth is preserved and the performance of mission critical applications is enhanced.


Ethernet encryption offers true scalability. Network complexity is reduced allowing easy deployment and simple management in thousands of devices. Additionally, Ethernet is transparent to upper layer topology changes, meaning that routing updates will not impact the security configuration or cause network outages. This benefit becomes critically important as agencies plan their migration from IPv4 to IPv6, as it allows network architects to preserve the existing security infrastructure throughout the transition.
