Bromium, whose micro virtual machine technology assisted IT administrators in trapping malware, raised USD40 million in investment capital. The size of the company's recent Series C funding round was large because it was oversubscribed. New investor Meritech Capital Partners led the round, with participation from existing investors Ignition Partners, Andreessen Horowitz, Intel Capital and Highland Capital Partners. The recent funding brought the total investment raised by bromium to USD75.7 million since its establishment in 2010.

Bromium's technology provided a different approach in protection from malware and other attacks. Bromium instead keeps a bad link in its virtual machine, wherein an IT administrator reviews it and disposes the link if it deemed unsafe.

The security technology Bromium provides, however, was deemed not perfect. UK-based Leading Edge Forum researcher Simon Wardley wrote in a post that there's no such thing as a perfect security system.

"Hence whilst Bromium does not prevent any zero day exploits being run, it reduces the impact of them to practically negligible. The fear is gone. Just because one email has been compromised, doesn't impact all the other emails or the other applications and environments on my machine," Wardley wrote.
