vArmour, a startup focusing on security of the data-defined perimeter, announced today that is has brought in $36 million in investments after closing a $15 million Series B round last December and a $21 million Series C round this month.

Menlo Ventures led last year's investment, while Columbus Nova Technology Partners, Citi Ventures, and Work-Bench Ventures headed up this month's funding. The large boost in funding brings vArmour's total to $42 million.

"We will use the capital to scale our development, operational, and sales teams," said vArmour CEO Tim Eades in an email to SDxCentral. "The interest from customers and partners for our security technology to protect their data centers has been huge and we are growing the team to scale and support this significant opportunity."

vArmour's strategy relies on securing the data defined perimeter to offer a more secured network. It utilizes software-defined networking (SDN) to provide better security, because SDN allows for better insight and control over the increased east/west traffic flows that data centers are experiencing.

Those traffic patterns call for security measures within the data center that are as complex as the applications and information they are there to protect. vArmour's goal is to secure the data-defined perimeter using SDN capabilities, giving companies immediate visibility and control over traffic regardless of whether their data center architectures are new or dated. Once it launches broadly, vArmour will offer more details on its upcoming products.

Although vArmour is currently working under the radar, it has been preparing for its eventual launch later this year by assembling a board of directors, as well as a robust team of developers to deliver new products that will help to visualize, manage, and protect the data center.
