Sonicwall
Sunnyvale, Calif.

Sonicwall was founded in 1991, but since it refocused on small-business clients in 2003, revenues for this IT security firm have jumped more than 85 percent. Its projected 2006 revenues are $175 million.

"Small businesses are spending more than enterprise, and their IT budgets are expected to grow twice as fast as enterprise spending. We're going to continue to see small businesses' economic power grow substantially."
