Cyber Security Leader Selects Silicom Edge System as its High-End Next-Generation Platform

– Initial orders totaling over $1M are in hand: full ramp-up expected to reach ~$2M/year – KFAR SAVA, Israel – February 9, 2026 – Silicom Ltd. (NASDAQ: SILC), a leading provider of networking and data infrastructure solutions, today announced that an existing customer, a Tier-1 cyber security leader, has selected one of its Edge systems as the platform for its next generation of a high-end product line. To date, initial orders of over $1M have been received for delivery in 2026, and quantities are expected to ramp to approximately $2 million per year. In parallel, discussions continue about additional products for the customer’s additional product lines.

“This design win demonstrates once again the strength of our product line and the design-win-generating power of our long-term customer relationships,” commented Liron Eizenman, Silicom’s CEO.

“When this prestigious customer first engaged with us several years ago, the focus was solely on networking server adapters. Over time, as they gained confidence in our technology, execution and support, our collaboration broadened to encompass the rest of our product lines. Consequently, last year the customer awarded us a design win for one of our Edge systems. Now, a year later, they have expanded our relationship further with an additional design win, selecting a more sophisticated, higher-end Silicom Edge system as their platform for a next generation product line. This progression underscores the strength of our portfolio: our product lines do not cannibalize one another. Instead, they serve different segments of the customer's roadmap, ensuring that each new design win stacks on top of the last to deliver consistent, additive revenue growth.”

Mr. Eizenman concluded, “Relationships like these, with trust, sales and upsells that build steadily over the years, have given us a thriving core business that is growing faster than we originally projected.  It represents a solid, stable basis from which we can pursue venture-like upside opportunities including AI inference, post Quantum cryptography, and white label switches.”
