SD-WAN Rankings: Fortinet Rises as VMware, Cisco, Aryaka Hold Steady

VMware-owned VeloCloud leads the software-defined wide area networking (SD-WAN) industry’s latest revenue rankings.

Research firm IHS Markit unveiled its second-quarter market share results for SD-WAN. VMware, Cisco and Aryaka took the top three for the fifth straight quarter, but Fortinet leapfrogged into fourth place over Silver Peak, Nuage Networks and Huawei. IHS ranked the companies based on revenue generated from SD-WAN “appliances and control and management software.”

The market rose 23% in the second quarter, and IHS Markit cites growing enterprise adoption. Large companies – some reaching as many as 5,000 offices – are replacing their routers in favor of equipment that works with SD-WAN technology.

“In our discussions with vendors, it has become apparent that most recognize SD-WAN as a mainstream technology,” said Josh Bancroft, senior research analyst at IHS Markit. “As a result, larger enterprises have begun to refresh their legacy, router-centric WANs with SD-WAN. Vendors are capitalizing on the refresh opportunities with customers that have large bases of aging router equipment.”

The study also projected total SD-WAN revenue to reach $4.4 billion in 2023. The SD-WAN results are part of IHS Markit’s Data Center Network Equipment Market Tracker.

Fortinet is “benefiting from large enterprise security appliance refresh,” according to IHS Markit. The cybersecurity vendor began appearing on the IHS Markit tracker last year and recently said it was betting big on its updated Secure SD-Branch solution to combine the best of SD-WAN, security, switching and other features.

“We’re hearing from an increasing number of customers who are concerned about the security risks associated with SD-WAN exposing branch offices to the internet,” said John Maddison, Fortinet’s executive vice president of products and chief marketing officer. “We believe our growing market share validates the need for Fortinet’s unique security-driven networking approach, which tightly integrates security and SD-WAN functionality into a single offering.”

Fortinet also signed a partnership with Windstream to become its second SD-WAN vendor alongside VeloCloud. Gartner listed Fortinet as a top three SD-WAN equipment market share holder several weeks ago.

Bancroft said the increasing number of remote workers is driving SD-WAN demand. North American radiologists installed about 200 SD-WAN appliances in their home offices in the second quarter, according to the study.

“In the future, we anticipate further deployments of SD-WAN appliances in the homes of remote employees, with either compact or more traditional appliance form factors being used,” Bancroft said. “Bonding LTE and broadband links ensure session failover for unified communications (UC) users. It also promotes the security of sensitive patient data through security policies that can be established at the device level by health care providers in orchestration portals.”

Mobile workers are also drawing the industry’s eye. Bancroft said vendors are still investing to make traffic steering available for …
