Software-defined wide area networking (SD-WAN) vendor VeloCloud announced that it has closed a $35 million Series D led by Hermes Growth Partners, bringing the company’s total funding to $84 million.

Other round participants included new investors, Telstra Ventures and Khazanah Nasional Berhad, as well as old investors New Enterprise Associates (NEA), March Capital Partners, Cisco Investments, and other undisclosed investors.

The new round of funding will be used for global sales and marketing  and for new product development.

Since its last round of funding more than a year ago, VeloCloud has seen its number of SD-WAN sites grow to more than 50,000. The company has also picked up a few big name customers including AT&T, Sprint, Mitel, TelePacific, Earthlink, and Windstream.

Last October, AT&T announced that it selected VeloCloud to offer two types of SD-WAN: a network-based system and an on-premises-based system. This allows the carrier to provide connectivity across multiple site types and provides an easy transition for customers with existing AT&T VPN services to expand its footprint.

Yesterday, the SD-WAN vendor also announced a new partnership with Tata’s new subsidiary business NetFoundry. Using VeloCloud’s SD-WAN, NetFoundry customers will be able to connect branch offices to its platform.

VeloCloud’s SD-WAN technology allows for wired or wireless broadband Internet, with or without MPLS connections. It also provides carriers and enterprises with more bandwidth and direct access to cloud applications and data.
