AT&T tops US carrier managed SD-WAN leaderboard


AT&T has achieved the top spot in the 2019 US carrier managed SD-WAN services leaderboard benchmark.

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.

Service providers included in the Challenge Tier citation hold between a 1% and 2% share of US carrier managed SD-WAN sites.


All remaining service providers are grouped in the Market Players classification and have a site share below 1%, this includes global network providers that manage US customer sites.

In alphabetical order, the 2019 list includes: AireSpring, Bigleaf, BT, CBTS, Cincinnati Bell, Cogent, Colt, Consolidated Communications, Cox, DQE Communications, FirstLight, Frontier, Intelsat, MetTel, Neutrona, NTT, Orange Business, PCCW Global, PS Lightwave, RCN Business, SES, SDN Communications, Segra, SingTel, Spectrum Enterprise, Sprint, Syringa, T-Systems, Tata, Telefonica, Telia Carrier, Veracity Networks, Virgin Media Business, Vodafone, Zayo among others.

Key findings from the 2019 full year research show that billable US installations of carrier managed SD-WAN services increased 89% in 2019 as well a number of position changes from 2018.

CenturyLink moved up to fourth position, which dropped Windstream from fourth to fifth position. Comcast moved up to seventh position from eighth in 2018, while Fusion dropped off the leaderboard into the Challenge Tier for 2019.
