The maker of Web-security and Web-filtering software projected net earnings of 16 cents to 17 cents a share. Non-GAAP earnings, which exclude stock-based compensation expenses and the related tax effects, are expected to be 24 cents to 25 cents a share. The earnings estimates match its prior guidance.
