SD-WAN's Shift to Security

While the key SD-WAN transformation use case was built around network cost and resiliency, its focus is now shifting to security.

Enterprises have moved to more internet connectivity. Traffic patterns have moved away from on-premise data centers to neutral colo facilities or cloud service providers/hyperscalers. And over the past two years, edge access has moved out of the corporate site—to home and remote connections.

These forces changed how enterprises approach network security, and SD-WAN vendors have responded with new partnerships and feature sets.

This review looks at enterprise security trends and how SD-WAN vendors have adapted to accommodate security needs.

Submarine Networks and the Digital Transformation of East Africa

But in 2016, submarine cable capacity reached 33 countries; seven sub-Saharan countries had access to three or more systems.

Today, Africa leads the globe in international bandwidth growth. This has been facilitated by improved international connectivity along the critical Europe-to-India-and-Asia submarine corridor that connects East Africa to the rest of the world.
