SD-WAN leverages and optimizes the management of wide area networks by using software to control and automate network operations. Unlike traditional WAN solutions, which rely on hardware-based configurations and manual adjustments, SD-WAN leverages software to dynamically route traffic over various network connections, such as MPLS, broadband, and LTE.

This approach improves network performance, enhances security, and reduces costs by enabling more efficient use of available bandwidth and providing centralized control and visibility. SD-WAN is particularly beneficial for organizations with multiple branch locations or remote offices, as it allows for flexible, scalable, and cost-effective network management.
