Boston, MA, at the Netezza User Conference, September 25, 2007 — Netezza Corporation (NYSE Arca: NZ), the global analytic appliance market leader, today announced that the Netezza Performance Server® appliance has completed and achieved the stringent and prestigious Common Criteria Evaluation Assurance Level (EAL) 3+ certification. Netezza’s active participation in the Common Criteria evaluation process signifies the Company’s commitment to providing users with solid product security.

“Achieving Common Criteria certification and an EAL3+ designation means that Netezza has obtained a critical assurance level that is recognized by the international community,” said Steve Williams, vice president and general manager, federal operations, Netezza Corporation. “With this certification, our government and commercial customers worldwide are assured that Netezza’s appliance meets stringent and standardized security requirements.”

Common Criteria is an internationally recognized set of guidelines (ISO 15408), which define a common framework for evaluating security features and capabilities of Information Technology security products. The standard consists of several predetermined evaluation assurance levels, each one more stringent than the last. Common Criteria allows vendors to have their products tested against a chosen level by an independent third-party testing laboratory. Common Criteria certifications are accepted by 24 countries through the CCRA (Common Criteria Recognition Agreement), including the United States government.

Netezza partnered with Corsec Security, a consulting firm with over nine years of validation experience in order to facilitate the prompt completion of the evaluation process. “Corsec is thrilled to have worked with Netezza on their Common Criteria evaluation,” said Matthew Appler, CEO, Corsec Security. “Common Criteria is a rigorous, lengthy process and Netezza’s dedication to this effort was apparent from the start. Netezza’s continuous hard work clearly exemplifies the commitment to their customers.”

The Netezza Performance Server appliance is built specifically to analyze terabytes of detailed data significantly faster than existing data warehouse options, at a much lower total cost of ownership. The NPS system stores, filters and processes terabytes of records within a single unit, analyzing only the relevant information for each query. Netezza has placed the CPU power next to the data, allowing the NPS system to speed through processes that would occupy most data warehouse systems for hours, or even days, thereby enabling dramatic increases in productivity across the organization.
