FOR IMMEDIATE RELEASE

FORTUNE-100 WAN OPTIMIZATION CUSTOMER
ORDERS ~$1.2M OF SILICOM’S BYPASS PRODUCTS

– Explosive Growth of WAN Optimization Market
Continues To Accelerate Silicom’s Momentum –

        KFAR SAVA, Israel, March 19, 2007 – Silicom Ltd. (NASDAQ & TASE: SILC) today announced that a Fortune 100 leader of the Internet Networking industry has ordered Silicom products valued at approximately $1.2 million. Silicom will deliver advanced BYPASS adapters to this recently-announced Design Win in three separate shipments over the next three months as required to meet the customer’s WAN Optimization appliance manufacturing schedule.

        These sizeable shipments, the largest that Silicom has shipped to this prestigious customer since securing a Design Win with them in late 2006 (as reported in December 2006 – http://www.silicom.co.il/pgx.php?p2=396), confirms the importance of the WAN Optimization market as a growth driver for Silicom. The fact that Silicom has won three Design Wins from major WAN Optimization market players demonstrates that its BYPASS adapters are increasingly perceived as the WAN Optimization industry’s continuity solution of choice. The BYPASS adapter’s ability to automatically reroute traffic around non-functioning components enables WAN Optimization appliances to assure continuous traffic flow in all conditions, safeguarding against network disruption of any kind. As such, BYPASS functionality is necessary in practically all WAN Optimization and gateway appliances.

        “The explosive WAN Optimization market started to be an important target market last year and has become an important incremental growth driver for Silicom,” said Mr. Shaike Orbach, President and CEO of Silicom. “The Design Wins that we have secured with WAN Optimization players have significantly expanded our platform of potential repeat sales, and have also made it easier to penetrate new customers in this exciting market. As an industry just beginning its growth trajectory, we believe WAN Optimization is a huge opportunity with the potential to become one of our primary revenue drivers.”
