ARUBA NETWORKS EXTENDS LEADERSHIP IN ENTERPRISE-WIDE SECURITY WITH THE ACQUISITION OF NETWORK CHEMISTRY’S WIRELESS SECURITY BUSINESS

RFprotect™ and BlueScanner™ wireless security technology will be integrated into Aruba’s secure mobility solutions to enhance intrusion detection and fortify attack resistance

Sunnyvale, CA, July 23, 2007 - Aruba Networks, Inc. (NASDAQ: ARUN), a global leader in secure mobility solutions, today announced the acquisition of Network Chemistry's line of award-winning RFprotect and BlueScanner wireless security products. Designed to automatically detect network vulnerabilities, intrusion attempts, and policy violations, the Network Chemistry products are in the forefront of wireless intrusion detection and prevention solutions, and complement Aruba's broad existing line of wired and wireless security products. Aruba plans to integrate the newly acquired products into its secure mobility solutions, as well as provide products and continuing support to existing Network Chemistry customers and partners.

"Aruba has consistently led the industry with respect to client-to-core security solutions, and with this acquisition we have now rounded out our RF Layer 1-2 security offerings," said Dominic Orr, Aruba's president and CEO. "Network Chemistry’s products have consistently won accolades for their ability to accurately find wireless network equipment, detect unauthorized devices, and enforce networking policies. By integrating this capability into Aruba's product family we will extend our position at the vanguard of wireless security providers. We look forward to working with, and providing uninterrupted support to, Network Chemistry's large base of existing enterprise and government customers."

Network Chemistry products covered by the acquisition include RFprotect Distributed, RFprotect Mobile, and BlueScanner. RFprotect Distributed is a patent-pending wireless intrusion detection and prevention system that uses a central security engine and purpose-built sensors to automate threat detection, attack prevention, and 'no wireless' policy enforcement. RFprotect Mobile is a portable analyzer for conducting site surveys, security assessments, and incident responses of wireless networks, while BlueScanner is a portable Bluetooth discovery and vulnerability assessment tool.

"This acquisition presents an array of technical and marketing synergies that Aruba can leverage to its advantage," said Paul DeBeasi, senior analyst at The Burton Group. "Wireless intrusion detection by itself is a point solution, but network security requires a system solution. Supplementing its existing security solutions with Network Chemistry's leading wireless intrusion detection technology gives Aruba a comprehensive system solution. Not only will Aruba add value to its security offerings, but it will also expand the base of prospects to which it can market products and services."
