Invincea, a cyber security vendor that focuses on combating zero-day attacks, has received $16 million in equity from Dell Ventures and Aeries Capital. Existing backers Grotech Ventures, Harbert Ventures, and New Atlantic Ventures also participated in the round, which brings in the firm’s total funding to an impressive $26.2 million.

The Series C investment was announced on Monday in conjunction with the previously undisclosed acquisition of Sandboxie, a provider of virtual containment software. The startup’s technology has already been baked into Invincea’s flagship FreeSpace solution, which can now automatically seal malicious code in an isolated sandbox that cuts off access to vulnerable system functions and personal data.

Nearly 10,000 organizations are using the software to protect their end-users, according to Invincea, which reported 200 percent year-over-year growth in the third quarter. Much of that can be credited to the channel, especially Dell, which provides a one year subscription of the FreeSpace-based DDP | Protected Workplace service with every Precision, OptiFlex and Latitude system.

Brett Hansen, the executive director of client software at Dell, commented that “investing in Invincea made perfect sense given the unique ability of their solution to address the increasing threat of targeted and zero-day attacks. We look forward to changing the endpoint security paradigm with Invincea as our partner, and as a Dell Ventures portfolio company.”

Dell’s participation in the round Invincea comes just days after the debut of the $300 million Strategic Innovation Venture Fund, which extends the hardware giant’s existing $60 million Fluid Data Storage Fund to cloud computing, Big Data and mobility. These technologies are viewed as central to the company’s product portfolio, which is being overhauled as part of Michael Dell’s ambitious push into the enterprise market.
