Columbus Nova Technology Partners also took part in the financing, which covered a $15m Series B round closed in December last year and a $21m Series C round.
The company said it planned to use the new capital to scale its development and sales teams.
Menlo general partner Pravin Vazirani and Columbus’ Mohsen Moazami will both join the vArmour board of directors following the investment.
Moazami said, “vArmour has the escape velocity to completely disrupt the security industry.
“We went all in on vArmour as I’m confident that vArmour’s continued growth will deliver a solution for the enterprise that can visualize, manage and ultimately protect the data center in a way we’ve never seen before.”
Citi Ventures managing director Arvind Purushotham added, “Our investment in vArmour is a testament to the potential for its technology to shape the future of enterprise security for the data center.
“As an organization that supports billions of secure transactions per day, Citi is dedicated to consumer trust, and vArmour’s management team shares our vision for the importance of enterprise security.”
