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 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.
