FOR IMMEDIATE RELEASE

SILICOM ACHIEVES DESIGN WIN WITH
ADDITIONAL TOP-TIER U.S.-BASED INTERNET
SECURITY COMPANY

– $400K Orders Received So Far to Replace Competitor’s Adapters in One of the
Customer’s Major Security Appliance Product Lines –

        KFAR SAVA, Israel, August 28, 2006 – Silicom Ltd. (NASDAQ & TASE: SILC) today announced that it has achieved a Design Win with an industry-leading U.S.-based provider of Internet security solutions. The customer will use the Silicom high-performance Fiber Dual-Port Gigabit Ethernet Server Adapters customized for use in network appliances, and has so far placed orders valued at $400,000. The customer is using Silicom’s sophisticated adapters in one of its top-selling security appliance product lines to replace the standard adapters of a major competitor.

        The customer is a world-leader in the area of security products and services that pre-emptively protect enterprise organizations against Internet threats. It uses proprietary, leading-edge technologies in the areas of vulnerability assessment and enterprise-wide intrusion detection/prevention.

        The Design Win followed a lengthy process of discussions and evaluations of various products, after which the customer began offering Silicom’s adapters to customers who required the special features of the Silicom offering. In parallel, the customer’s contract manufacturer, which uses Silicom’s products in appliances that it builds for another top-tier security company, recommended Silicom’s adapters as a superior solution. The combination of the customer’s positive experience and the recommendation of the contract manufacturer then led the customer to standardize on Silicom.

        “This Design Win contributes substantially to our growing momentum in an expanding marketplace,” said Mr. Shaike Orbach, President and CEO of Silicom. “On a technological level, the fact that another leading security industry player has replaced a competitor’s adapter with ours is a strong validation of our card’s superiority. Further, the fact that we were recommended by a top-tier contract manufacturer demonstrates the differentiated standing that we have achieved in a competitive industry, a reputation that will help us generate additional business opportunities. Taken as a whole, with industry-leading products, top-tier customers and a superb team, we have established an excellent business foundation, and are building on it to take Silicom to the next level.”
