Bluebox, a start-up developing the next evolution in enterprise security technology, announced today that it has closed a $9.5 million Series A financing round led by Andreessen Horowitz. Additional investors include Andreas Bechtolsheim, co-founder of Sun Microsystems and one of the first investors in Google, SV Angel, Ram Shriram, board member of Google and one of its first investors, and Brian Cohen, former CEO of SPI Dynamics (acquired by HP). Along with the initial round of funding, Bechtolsheim and Scott Weiss, general partner at Andreessen Horowitz, have been named to the company's board of directors.

Bluebox is founded by veteran entrepreneurs with strong security DNA. Bluebox CEO and co-founder Caleb Sima served as Chief Technology Officer for HP's Application Security Center and was responsible for directing the lifecycle of the company's web application security solutions. He joined HP following the acquisition in 2007 of SPI Dynamics, the company he co-founded and led as CTO, where he oversaw the development of WebInspect - a solution that set the bar in Web application security testing tools. Prior to co-founding SPI Dynamics in early 2000, Caleb worked for Internet Security Systems' elite X-Force R&D team and as a Security Engineer for S1 Corporation.

Co-founder Adam Ely was previously CISO of the Heroku business unit at salesforce.com. Prior to salesforce.com, Adam led security operations, application security, and compliance for TiVo. Before TiVo, he led security functions within The Walt Disney Company, responsible for properties including ABC.com, ESPN.com, and Disney.com.

"Enterprise security on mobile is an unsolved problem, and, frankly, is in need of innovation," said Bechtolsheim. "Bluebox is developing a solution that will change the way enterprises think of how to successfully and seamlessly protect their data."

"This is the most amazing security team that I've seen in a long time," said Scott Weiss, general partner at Andreessen Horowitz and former CEO of IronPort Systems, which was acquired by Cisco. "They are going after one of the hardest problems that companies face and where incumbents have floundered."
