Exhibit 99.1

Allot Notified of Class Action Lawsuits

Hod Sharon, ISRAEL – May 3, 2007 – Allot Communications Ltd. (NASDAQ: ALLT), a leader in IP service optimization solutions based on deep packet inspection (DPI) technology, announced today that it has been notified that purported class action complaints had been filed in the United States District Court for the Southern District of New York against the Company and certain of its directors and officers. The complaints allege that the Company failed to disclose in the registration statement for its initial public offering that at the time of the IPO it was experiencing declining sales “in its indirect distribution channels, such as enterprise, education and smaller ISP customers, in North America,” and on that basis the complaints assert violations of U.S. Federal Securities laws.

The Company believes that the allegations made in the complaints are without merit and that it intends to vigorously defend itself against the complaints.

These forward-looking statements are made only as of the date hereof, and we undertake no obligation to update or revise the forward-looking statements, whether as a result of new information, future events or otherwise.
