What are the benefits of Cisco SD-WAN? Traditional WAN architecture is limited between enterprise, branch, and data center. As businesses adopt cloud-based application services in the form of SaaS/IaaS, their WAN architecture experiences an explosion of traffic accessing these globally diverse applications. With Cisco SD-WAN, organizations can deliver routing, threat protection, efficient offloading of expensive circuits, and simplification of WAN network management.
