In 2015, Nuffield Health, a UK-based healthcare organization, was preparing to undertake several projects aimed at improving productivity, efficiency, and patient services, while enhancing user experience across its corporate office, hospitals, and gyms. These projects included a migration to Microsoft Office 365 and the introduction of TrakCare, a new electronic health record application. However, the success of these projects was heavily dependent on the performance of Nuffield Health's network, which needed to secure sensitive patient and personal data flowing in and out of its facilities. At the time, Nuffield Health had only one MPLS network link running at 30 MB at each of its sites, which was insufficient for the upcoming projects and the required resiliency. Furthermore, 60% of its traffic was already destined for the internet rather than its data centers, a percentage that would increase significantly once Office 365 was deployed. The team realized that it needed more bandwidth and more resiliency in its network, and it needed to consider the cost and latency resulting from backhauling all that traffic through the data center. It also had to determine the best way to secure all that internet-bound traffic.

The National Transportation Safety Board (NTSB) was facing significant challenges with its legacy network infrastructure. The agency, which is responsible for conducting independent accident investigations, advocating safety improvements, and deciding pilots’ and mariners’ certification appeals, has a highly mobile workforce that conducts investigations throughout the U.S. in varied environments. However, the requirement to route all traffic through a legacy Trusted Internet Connection (TIC) was not designed to handle an increasingly mobile workforce. This resulted in latency and connection issues, creating a poor user experience and negatively impacting NTSB’s mission. Additionally, the traditional model of routing remote connections through a VPN client, to the agency data center, through a stack of on-premise security devices, and back out through the TIC, where it traversed another stack of security appliances to its destination, was frustrating for remote users and complicated security.

Siemens, a global leader in energy-efficient, resource-saving technologies, was facing a challenge with its traditional hub-and-spoke network architecture.
