Late last year I moderated a MicroScope roundtable in the UK on the challenges and opportunities of SD-WAN. The representatives included 12 leading SD-WAN vendors, including Michael O’Brien, vice president of worldwide channel sales for Silver Peak. I started off the discussion by introducing a data point from a TechTarget survey (TechTarget owns MicroScope) that only 26 percent of companies surveyed had an SD-WAN deployment underway. This spans any stage of the deployment cycle, including testing. Given the hype around SD-WAN and how many conversations I have with IT leaders about it, this number seemed low to me, so I wanted to get a better feel for what the leading vendors thought about it.
