Changes brought about by digital transformation are pressuring traditional wide area networks (WANs) because of expanded public-cloud workloads, mobile connectivity, and the security ramifications of network traffic shifting from secure corporate data centers to branch offices. Enter the software-defined WAN (SD-WAN), which uses network virtualization and cloud-based technologies to simplify the delivery of WAN services, accelerate deployments, and deliver deep visibility and control across the network.
In this guide, we explain:
- Today’s network challenges, as described by enterprise IT leaders
- How SD-WAN delivers new functionality that answers these challenges
- What to look for in a secure SD-WAN solution
- Key elements of a truly unified SD-WAN offering.
