Bluebox, an enterprise security startup, has secured a fresh $18 million round of funding, the company announced today.

Bluebox focuses on making mobile tech secure for businesses, which is even more important given the number of people who conduct both company and personal business from a sole smartphone. The company is still in stealth despite launching nearly two years ago, but is planning to unveil a public service February 19, according to founder Caleb Sima.

The company said it plans to use the new capital to scale its sales and marketing operations in anticipation of next month’s launch.

The round itself, Bluebox’s second, came from new investor Tenaya Capital as well as existing investors Andreessen Horowitz, Sun Microsystems Co-founder Andreas Bechtolsheim, and SV Angel. As part of the funding deal, Tenaya’s Brian Melton will also join the company’s board of directors.

Founded in 2012, the San Francisco, Calif.-based startup has raised a total of $27.5 million in funding to date.
