The challenge for Senetas 

Our client, a defence sector provider operating across multiple sites in the United States and Europe, was mandated by the US Government to encrypt its wide area network.

As a contractor handling Controlled Unclassified Information (CUI), the organisation needed to meet NIST SP 800-171 — the federal standard for protecting sensitive information within non-federal systems — or risk losing eligibility for government contracts.

The network itself presented a layered challenge:

  1. A combination of Metro Ethernet and point-to-point links, with some point-to-point connections running MPLS on the local side.
  2. The need to work transparently across this mixed infrastructure, protecting data in transit without adding latency, breaking existing routing or requiring redesign.

Our team designed and delivered a certified encryption layer that could sit across this environment end-to-end. Furthermore, the solution met the compliance mandate without necessitating redesign of the network itself.  

We used a combination of Senetas CN6140 and CN9120 network encryptors at key sites, providing certified encryption that sits transparently across mixed Ethernet network topologies, including the point-to-point segments running MPLS underneath.
The client is now extending the deployment of our solution to additional sites.

Outcomes in summary 

  • CN6140 and CN9120 certified network encryptors across US and European sites

CN6140

CN9120

  • Protocol-transparent encryption across mixed Metro Ethernet and MPLS point-to-point infrastructure
  • Compliance with NIST SP 800-171 for protecting Controlled Unclassified Information (CUI)
  • Zero impact on network performance or existing routing during rollout
  • Encryptors independently certified to FIPS 140-2/140-3 Level 3, providing confidence in a defence-grade security posture
  • A proven solution for rolling out to further sites
