Network engineering and operations leaders are looking to software-defined widearea networks (SD-WAN) to support the influx of traffic and applications driven by digital transformation (DX). These applications improve staff productivity while creating new business opportunities, but they also reshape corporate networking and security needs.

In response, many organizations are beginning to rethink their traditional WAN architecture. SD-WAN has emerged as a replacement, but many SD-WAN implementations also present serious challenges—from inadequate security to high total cost of ownership (TCO). Understanding these issues is key to navigating the increasingly complex market for WAN edge technologies.
