FOR IMMEDIATE RELEASE

SILICOM ACHIEVES DESIGN WIN WITH ANOTHER
WORLD-LEADING WAN OPTIMIZATION PLAYER:
4TH DESIGN WIN IN EXPLODING MARKET

– First Production Quantities Already Shipped –

        KFAR SAVA, Israel, April 4, 2007 – Silicom Ltd. (NASDAQ & TASE: SILC) today announced that it has achieved a new Design Win for its BYPASS adapters with a U.S.-based global leader of the WAN optimization market, and that it has already delivered production quantities against the customer’s purchase order.

        The customer’s scalable WAN Optimization appliances are used by thousands of companies to monitor, shape, compress, accelerate and manage application traffic across all WAN links, whether in data centers, branch offices or remote sites. Silicom’s BYPASS adapters will be deployed in one line of the customer’s appliances to assure continuous traffic flow in the event of network disruption, automatically rerouting traffic around non-functioning components.

        In total, Silicom is now supplying BYPASS products to six suppliers of WAN Optimization appliances. In addition to the four Design Wins it has achieved in the booming WAN Optimization market, Silicom is also shipping BYPASS products to two security customers that have extended their offerings to include WAN Optimization solutions. This demonstrates that Silicom’s BYPASS adapters have become the continuity solution of choice for WAN Optimization appliances.

        “We are witnessing explosive growth in the Wan Optimization market, and believe that it will become a multi-billion dollar market that will last at least 2-3 years, benefiting many players including Silicom,” said Mr. Shaike Orbach, President and CEO of Silicom. “With four major WAN Optimization Design Wins and a growing flow of orders, including the $1.2 million repeat order that we received about a month ago from a Fortune 100 networking leader, we are more excited than ever regarding the WAN Optimization market’s potential to drive our revenues to a new level. To take full advantage of the opportunity, we continue with aggressive sales efforts to extend our market penetration.”
