US-based stealth security company VArmour raised $21m on Wednesday in a series C round that included Citi Ventures, financial services firm Citi’s corporate venturing unit.
There was also involvement from venture capital firm Menlo Ventures, accelerator Work-Bench and investment firm Columbus Nova Technology Partners.
VArmour helps users understand how network traffic flows throughout their data centres in order to prevent hacking attacks. The new funding will enable the company to meet product demands and expand its sales team.
Pravin Vazirani, general partner at Menlo Ventures, and Mohsen Moazami, managing director of Columbus Nova Technology Partners, will join VArmour’s board of directors in conjunction with the funding.
VArmour raised $15m in a series B round in December 2013 from Menlo Ventures, which followed a $6m series A round led by Highland Capitalo Partners in January 2013. Prior to that, the company raised $2m in seed funding.
VArmour has been in stealth mode since being founded in 2011 and has raised $42m to date. It is now preparing for a late 2014 launch.
