SD-WAN

Software that intelligently manages traffic across multiple internet connections at a site, for reliability and speed.

SD-WAN lets a business combine multiple connections (e.g. a leased line plus a broadband backup) and intelligently route traffic across them — prioritising business-critical traffic, failing over automatically if one connection drops, and often reducing cost compared to a single expensive dedicated line. It earns its keep once you're managing more than one site or a lot of cloud/remote traffic.
