NEW YORK (TheStreet) -- RATINGS CHANGES Allot Communications was downgraded at Barclays to underweight from neutral. Twelve-month price target is $9. Allot is a company in transition as the core DPI business slows and its focus shifts primarily to value-added services, Barclays said. This transition will affect revenue, size of deals, geographic mix, bookings and backlog trends, Barclays also said. Borderfree was downgraded at Canaccord Genuity to hold from buy.
