SD-WAN: Software-Defined Wide-Area Network is an application of Software-defined Networking technology applied to Wide Area Networks (WAN). SD-WAN simplifies the administration, management, and operation of a WAN by decoupling the networking hardware from its control mechanism. It connects enterprise networks — including branch offices and data centers — over large geographic distances.

In this blog, we have discussed the Top Best SD-WAN Companies & Providers available in the market. The information is gathered from various resources such as the Gartner WAN Edge Infrastructure report Published on 26 November 2019.
