WLAN vendor Aruba has nearly doubled its market share since going public in March. Thanks to going public, customers are comfortable with Aruba's long-term viability, says Aruba founder Keerti Melkote. Aruba recently won a contract with Prudential Fox & Roach, the country's largest single-market real estate firm. It has landed several high-profile contracts, including a deal with the U.S. Air Force, Ohio State University and Microsoft.

Aruba reported in May that revenue increased to $34.7 million, up 30 percent quarter over quarter and up 65 percent from the previous year. It was the company's first break-even quarter since its inception in 2002.

However, Aruba has a long way to go before it catches up with heavyweight Cisco. According to research company Dell'Oro Group, Cisco's market share sits around 64 percent.
