Security software maker Fortinet's results beat estimates

(Reuters) - Security software maker Fortinet Inc reported better-than-expected quarterly profit and revenue as businesses spent more to protect their networks and data.

Fortinet's net income fell to $41.1 million (25.61 million pounds), or 2 cents per share, in the third quarter ended Sept. 30, from $11 million, or 7 cents per share, a year earlier as it spent more on marketing and research and development.

But excluding items, the company earned 12 cents per share, beating the average analyst estimate of 11 cents, according to Thomson Reuters I/B/E/S.

Revenue rose 25 percent to $193.3 million, exceeding the average forecast of $184.9 million.

Fortinet's shares were up about 1 percent at $25.45 in extended trading on Wednesday.
