Allot Communications Revises Revenue Outlook for 2007

Announces Date for Quarterly Conference Call

Hod Hasharon, ISRAEL – October 9, 2007 – Allot Communications Ltd. (NASDAQ: ALLT), a leader in IP service optimization solutions based on deep packet inspection (DPI) technology, today announced that the Company now expects to report revenues for 2007 in the range of $32 million to $35 million, which is lower than its previous guidance.

The Company anticipates that based on preliminary results for the third quarter ended September 30, 2007, revenues for the quarter will be approximately $7.0 million. These results reflect slow sales during the quarter coupled with delays in customer purchase decisions due to growing interest in the Company’s newly introduced 10GB Service Gateway product. In addition, during the quarter the Company received a $2 million order from a major telcom operator in Latin America. The Company expects that revenues from this order may be recognized over an extended period of time, most likely commencing during 2008.

The annual revenues are also expected to be affected by longer than originally anticipated sales cycles for the Company’s Service Gateway. The Company recently commenced trials of the Service Gateway product with potential customers and expects to generate some initial revenue from this product during the fourth quarter.

“Overall, despite the lumpiness in sales we are experiencing this year, we remain confident in our service provider strategy, our ability to execute on this strategy and on the long-term outlook for our DPI products,” said Rami Hadar, Allot’s President and CEO.
