The annual listing from Vertical Systems Group named AT&T, Hughes, Verizon, CenturyLink, Windstream, Aryaka and Comcast, as the top seven SD-WAN service providers in the US.
Each company holds 2% or more of installed and billable carrier managed SD-WAN customer sites, which the ranking is based on.
"The US managed SD-WAN market expanded rapidly in 2019 as backlogged orders from the prior year were fulfilled by key service providers," said Rick Malone, principal of Vertical Systems Group.
"While the duration and depth of the coronavirus economic collapse is unknown, we expect resiliency across bandwidth intensive VPN markets, but acute vulnerability for the SD-WAN networks supporting the retail and travel verticals."
Following the aforementioned top seven, the listing includes a further five companies that achieved a Challenge Tier citation, these are Fusion, GTT, Masergy, Meriplex and TPx – listed in alphabetical order.
