Fortinet's guidance and CFO comments have been added to this story. SUNNYVALE, Calif. ( TheStreet) -- Fortinet's ( FTNT) star is still firmly on the rise, if the security specialist's first-quarter results, released after market close Wednesday, are anything to go by. The hardware maker reported revenue of $93.3 million, an increase of 34% compared to the same period last year, and a post comfortably above analysts' estimate of $86.9 million. Excluding items, Fortinet earned 17 cents a share, up from 8 cents a share in the prior year's quarter. Analysts surveyed by Thomson Reuters were looking for earnings of 14 cents a share. "The first quarter marked a strong start to the year for Fortinet with solid execution and a healthy pipeline of business," said Fortinet CEO Ken Xie, in a statement. "Our recent investments in our global sales organization and sharpened focus on penetrating the large enterprise have resulted in significant momentum in our business across geographic regions."Boosted by demand for its products, the company increased its cash position during the first quarter.

Fortinet's cash flow from operations was $40.2 million, up from $21.8 million 12 months ago. "I don't think that there were any negatives that we saw
during the quarter ," Fortinet CFO Ken Goldman told TheStreet. "We were able to overcome a couple of challenges in Japan and the turmoil in the middle east - we were able to compensate for that in other areas." Fortinet's total billings in the Americas, for example, rose 64% year-over-year, according to the CFO. For the second quarter ending in June, Fortinet expects revenue between $95 million and $96 million and earnings between 16 cents and 17 cents a share. Analysts currently anticipate sales of $92.1 million and earnings of 15 cents a share.
