Software-defined wide-area networking (SD-WAN) provider Viptela today announced a $75 million series C round of financing.

The round was led by Redline Capital with participation from new investor Northgate Capital and prior investor Sequoia Capital. It brings the company’s total funding to nearly $110 million.

As part of the financing, Tatiana Evtushenkova, director of Redline Capital, has joined the Viptela board of directors.

The company says the proceeds will go toward sales, marketing, technical support, and research and development. It also plans to expand into new geographies.

Viptela says it has 25 Fortune 500 customers, including the carriers Verizon and Singtel, which use its technology to offer managed SD-WAN services to their business customers.

One of the big selling points of SD-WAN is that it allows businesses to reduce usage of redundant MPLS connections, which can get very expensive for organizations with hundreds of branch office sites.

The Viptela platform allows enterprises to reduce WAN costs by augmenting expensive leased lines with cheaper public broadband connections.

Viptela’s SD-WAN technology could even move into the Internet of Things (IoT) category. It recently touted the technology as a way to manage the connections to bank ATMs.
