ESG conducted research on the drivers, levels of adoption, perceptions and procurement sources for SD-WAN by surveying 300 IT professionals responsible for evaluating, purchasing, and managing networking technologies
We found out that 3 in 4 organizations are either using or plan to use SD-WAN. So what are the drivers? It's not one thing, but a combination of reasons such as security improvements, increased bandwidth and simplified management.
What's surprising is that there also isn't one source for procurement. Whether it's a general networking vendor (I provide a small sample of potential vendors in these categories: Cisco (Viptela), Juniper, VMware (Velocloud), etc.), a network service provider (ATT, Verizon), specialized SD-WAN vendor (Aryaka, Cato Networks, CloudGenix, Talari), general WAN vendor (Riverbed, SIlver Peak), or a special managed network services provider (MetTel), the path is open for all of these choices and I think the space is open for many companies to choose from, and, from a vendor's perspective, to co-exist. Many of these vendors offer multiple paths to end-user adoption: It may include direct to the customer in a DIY method, or sales via a telecommunications service provider partner, so the mapping of firms is not exclusive to one category. Furthermore, firms like Aryaka and Cato Networks have created software and operate a service as well.
