Finjan was a company which provided enterprise web security solutions, including real-time and behavior-based malware prevention, before being acquired by M86 Security in 2009. Finjan continues to hold patents for various Web security technologies. Prior to this acquisition, the company was headquartered in San Jose, California
Finjan was founded in 1997 by Shlomo Touboul, a serial entrepreneur who founded his first company, Shani Computers, in 1985 and sold it to Intel in 1994. He then worked for Intel for a while, before starting Finjan. In 1998 Touboul decided to bring in an experienced seasoned CEO, who would be able to develop and grow the company more quickly, he then left to start his own venture capital fund.
In 2001, the company ran into financial difficulties and Touboul was asked by the board of directors to rejoin the company as CEO. Touboul realigned the company's strategy, moving away from developing only software solutions to combined hardware and software security appliances; additionally, the company moved to a channel sales model. In December 2002 Finjan acquired  the assets of Alchemedia, a software developer with a DRM product called Clever Content, and several DRM patents; Alchemedia also had ties to Israel, as its founder Daniel Schreiber was Israeli, though the company was technically headquartered in the Dallas area. In 2005, following disagreements with the board, Touboul left again and started a new company Yoggie Security Systems.
In November 2009 the company was sold to M86 Security, a global computer security firm based in Orange, California with international headquarters in London and offices worldwide.
Finjan appliances are now sold as Trustwave Secure Web Gateway.
Finjan was privately owned and its major shareholders included Cisco, Microsoft, Bessemer Venture Partners, Benchmark Capital, HarbourVest Partners and Israel Seed Partners. In November 2008, the company secured an additional investment of $22M, which brought the total capital invested in Finjan since its founding to $67 million.
