The onset of digital transformation (DX) has introduced new technologies and solutions alongside lower-cost connectivity options for business, resulting in many organizations modernizing their legacy wide-area networks (WANs). With more and more data becoming digitized, the emergence of the public cloud, including the adoption of Software-as-a-Service (SaaS) applications, necessitates a redesign of the WAN architecture, specifically the branch, edge network, and security architecture. Software-defined WAN (SD-WAN) solutions leverage corporate WAN and multi-cloud connectivity to protect application performance at the network edge of branch sites.
