Cisco says 20,000 customers use its SD-WAN technology. This number, as of its first fiscal quarter of 2020, includes the vendor’s Viptela and Meraki product lines. And, according to a blog touting the customers count, this crosses all industries and the globe.

Some 70% of the Fortune 100 use Cisco’s SD-WAN as of August, the vendor claims. As more companies adopt this SDN technology — IDC research shows that almost 95% of the enterprises they surveyed expect to be using SD-WAN within 24 months — the race to grow revenue and customer counts becomes even more intense.

SD-WAN market reports consistently show Cisco and VMware jockeying for the No. 1 spot. IHS Markit’s most recent report puts VMware at the top of the pack with Cisco close behind, while IDC says Cisco leads the market.

But while Cisco today disclosed its SD-WAN customer count, VMware hasn’t yet followed suit. It’s worth noting, however, that VMware this afternoon will report earnings for its third fiscal quarter of 2020. So, it’s possible the vendor will announce its customer count at that point.

For comparison, Silver Peak, another leading SD-WAN vendor, last month said it surpassed 1,500 customer deployments. Versa Networks, meanwhile, claims 1,000 enterprise SD-WAN customers. In other words, Cisco is winning by a wide margin. At least until VMware weighs in with its customer count.

In the blog post, Sachin Gupta, SVP of product management for Cisco enterprise networking, says his company’s SD-WAN is part of its bigger strategy “to deliver multi-domain networking with an intent-based architecture.”

Gupta wrote that semiconductor testing company National Instruments selected Cisco SD-WAN powered by Viptela because it needed more bandwidth across its 88 sites. “National Instruments’ new network has 30 times the bandwidth of their previous solution, it’s easier to manage, and it’s less expensive to run,” he wrote.

Other customers highlighted in the blog include plumbing company Reece Group, with 5,000 employees and more than 600 branches in Australia and New Zealand; and Associated Bank, which is Wisconsin’s largest bank. The bank deployed the Meraki MX platform to meet their needs, and Associated’s network architect Tim Larson says this saved the company more than $500,000 annually while improving its average bandwidth to branches by 7,800%.
