CloudPassage raises $14M for cloud security

The company's flagship product, Halo, has driven a big boost in subscriber growth

CloudPassage, a San Francisco-based cloud server security provider, announced Wednesday that it has raised $14 million in a Series B round led by Tenaya Capital, with help from existing investors Benchmark Capital and Musea Ventures.  The round brings the company's total raised to more than $21 million.

Founded in 2009, CloudPassage is off to a strong start this year, with subscriber growth up 70% in the first two months of 2012 compared to the first two months of 2011.  The company now has "thousands of servers under protection, with hundreds of companies using the tool in active deployments," according to CEO Carson Sweet.  (Side note: best CEO name ever.)  Some of CloudPassage's more notable customers include FourSquare, StrongMail, Exois, Avatar New York, and more.

What's fueling the company's growth?  It could be the number of customers who are drawn to CloudPassage's award-winning cloud security server platform Halo, which was built to operate across public, private, and hybrid clouds.  Halo automates firewall management, vulnerability management, network access control, server account administration, and security event alerting.

CloudPassage released Halo Professional in November for 10 cents per server hour, and Halo NetSec in February for 3.5 cents per server hour.  Halo Basic is free and protects up to 25 servers.

“We’re excited to have the continued backing and expertise of top-tier investors; both Benchmark and Tenaya are well-known leaders who strengthen the company’s ability to refine and execute on our vision," said Sweet, in a statement.

The company plans to use the new funds to drive market penetration of Halo.
