As noted earlier, Needham analyst Alex Henderson upgraded Allot Communications to Buy from Hold with a price target of $6.35, citing the results from the company's adjusted focus from Deep Packet Inspection, or DPI, technology to Service Provider Network Intelligence and Security. The analyst notes that he has "patiently" watched the transition, but now believes that the strategy has "taken hold", anticipating Allot to produce "double digit growth, improving margins and returning to profitability in 2019". Henderson adds that the company's recent wins are indicative of the strategy's progress.
