Software-defined wide-area networking (SD-WAN) has been growing rapidly on the corporate side of many organizations. Its benefits have been convincing CIO’s everywhere to ditch their expensive MPLS links for a better WAN technology for connecting their branch locations. Recently, the OT side of the house has started to realize that SD-WAN makes a lot of sense for their distributed operational environments as well. As a result, OT environments are adopting SD-WAN to realize key benefits including reliable connectivity, simplified management, and lower total cost of ownership. Of course, OT asset operators have some specialized needs for deploying an SD-WAN solution at their non-environmentally controlled locations that include, among others, something that is secure, compact, rugged, and able to be remotely deployed, managed, and monitored.
