The series B round was led by Tenaya Capital and included existing investors Benchmark Capital and Musea Ventures. Tenaya's Brian Melton will join CloudPassage's board.
The company says it will use the funds to continue upgrading and selling Halo, its cloud server security platform. It has been aggressively courting customers after it introduced Halo Professional in November and Halo NetSec in February. (It also offers a basic, free version for up to 25 servers.)
The platform offers cloud firewall management, vulnerability management, network access control, server account administration and security event alerting across public, private and hybrid clouds.
With the cloud security market expected to grow, investors see opportunity.
"We invested in CloudPassage based on the company’s ability to deliver innovative products that address a large market opportunity," Tenaya's Melton said. "Security has been a key barrier to cloud adoption, and the company’s comprehensive cloud server security platform is well positioned to solve this problem."
