When designing a network to connect central and far-flung offices, IT leaders are increasingly turning to a Software-Defined Wide-Area Network (SD-WAN) overlay. A software-defined wide-area network (SD-WAN) is a virtual WAN architecture that's service provider-agnostic. This allows enterprises to leverage any assortment of transport services to securely link to desired applications. The list of transport services includes broadband Internet, Multiprotocol Label Switching, and Long-Term Evolution (wireless).
The increasingly popular and flexible SD-WAN architecture provides a network overlay and decouples network software services from hardware-provided WAN links. SD-WAN gives you a wide array of cost-effective and versatile services with which to build and enhance your enterprise network to meet today’s ever-changing business needs.
Catalyst SD-WAN connects any user to any application with integrated capabilities for multicloud, security, predictive operations, and enhanced network visibility. The offering enables you to deliver network connectivity that’s cloud-agnostic, efficient, and simple to manage, lowers operational costs, and increases control and visibility.

Researching SD-WAN providers requires much vendor-specific information gathering. It includes reading reviews, use cases, and provider rankings – from top independent entities – such as Garner Group. Vendor websites provide a good deal of information. Following coverage and explanation of current trends, pros and cons, and user case studies is also essential. Published buyers' guides are also an asset.
Before diving into the deep end of the pool, it’s paramount to lay out your company’s WAN needs today and going forward. What strategic business goals are on the to-do list, and what capabilities do your employees need to reach them in the most effective manner and shortest timeframe?
Check on SD-WAN pricing and project costs, as they are top considerations in the transition and ongoing operations. How do they compare to those of other providers? Are there discounts or other breaks for businesses that bundle SD-WAN with other services? Don't forget possible incentives for long-term service commitments.
A crucial part of your research process, time spend poring over posted reviews by customers, and media outlets is time well spent on SD WAN. Perhaps users in your vertical industry would share their candid experiences with SD WANs with you. Also, ask providers for a list of customer references.
A final suggestion on the customer reviews front: check to see if providers have more than a few reviews and if any are current. Be wary of reviews from unnamed customers and from those that are superficial and lack useful specifics.
It's important to determine if an SD-WAN solution provider is truly aware of its competition, large and small. Push beyond those that dismiss rivals out of hand and those that appear to lack a comprehensive understanding of the market sector – which is growing by the quarter. Compare the financials of rivals with an eye to revenue growth and investment in SD-WAN product evolution.
When researching SD-WAN solution providers, don't forget to seek out and speak with qualified staff members who can discuss with you the top issues, challenges, and advances in this increasingly crowded space. This can require separating marketing and communications staff from solutions engineers and those in charge of defining product development. Credentials are key.
For this potentially make-or-break aspect of research, you and your company's security experts should evaluate all relevant SD-WAN provider materials and discussions regarding each solution's current features, capabilities, and strengths in detail. Security feature plans should also be discussed.
It could prove useful in discussions with SD-WAN solution providers to determine if they have experience – and installations – in different vertical industries, as one size doesn't necessarily fit companies from diverse lines of business. A solution that does well with manufacturers may not be as effective in the financial tech space. Seek out provider customers in your industry.
Feel free to ask your own staff, SD-WAN providers, current users, market researchers, and industry experts questions wherever necessary in this core undertaking to prepare yourself for shortening the contender list to semi-finalists and finalists. Be wary of those who avoid, dodge, or simply can’t respond to queries in the above-listed areas.
