Gigamon Expands Warranty Coverage on All GigaVUE Data Access Switches and G-TAP Network TAPs

Five-Year Warranty Applies to All Hardware Components

MILPITAS, California, February 15, 2011 - Gigamon(R), the leading global provider of data access solutions, today
announced a five-year hardware warranty for all GigaVUE(R)
(www.gigamon.com/gigamon-products) and G-TAP(R)
(www.gigamon.com/g-tap-network-tap) appliances.

The new warranty covers all hardware components from chassis to
transceivers, and demonstrates Gigamon's solid commitment to ensuring the
highest levels of quality in the design, manufacture, and testing of its
products. As a result, organizations can feel confident in their Gigamon data
access solutions, knowing that they are using products that have met the most
rigorous quality standards in the industry.

"The Gigamon manufacturing team plays a vital role in our quality
standards. Before shipping any GigaVUE or G-TAP appliance, the products must
pass a meticulous 120-hour burn-in test in a lab where temperatures often
exceed 100 degrees with all ports running at full line rate," said Patrick
Leong, CTO at Gigamon. "Gigamon is committed to excellence in quality
assurance, engineering carrier-class network monitoring architectures and
technologies that help customers save valuable time, money, and resources."
