SAN MATEO, Calif., — March 19, 2002 — Keynote Systems, (Nasdaq:KEYN), the Internet Performance Authority®, today announced new versions of its flagship services, Web Site Perspective™ 6.0 and Transaction Perspective™ 4.0, that give users many new next-generation diagnostic and operational features targeted at the enterprise.

With the availability of the two new services Keynote fundamentally redefines performance benchmarking to include diagnostic capabilities making them an integral part of a complete application performance management solution. The new features include instant drill down from the alert message to the cause of the problem, side by side graphing of performance and availability, complete page element detail available and faster problem notification. The new capabilities are not available from any other vendor today.

The shift towards greater diagnostics and operational functionality represents a broad new approach across Keynote's family of services that permits large enterprises to improve service level management, third party content management and operational efficiency through faster problem resolution.

Web Site Perspective 6.0 and Transaction Perspective 4.0 allow users, for the first time, to graphically view real-time performance and availability metrics side by side and immediately correlate the two. Easy to learn and use, with immediate diagnostic results, Keynote's new benchmarking approach reduces training time, increases staff competency and saves time, allowing customers in just three clicks to drill down from an alarm to discover when, where and why a problem occurred.

"REI's mission is to provide high quality goods and exceptional service. Our Web presence is an important part of our business and it is critical that our Web site perform at optimal levels. REI sets the standard in Web performance and Keynote helps us provide our visitors with a superior customer experience which is a priority," said Rod Ketchum, systems architect, Recreational Equipment Incorporated. "As a long-time supporter and customer of Keynote, we believe that the diagnostic and operational enhancements to Web Site Perspective 6.0 are a quantum leap in our ability to isolate problems and address them quickly."

E-businesses require operational functionality in their performance management services, a broader (end-to-end) view into their e-business applications and greater value in terms of diagnostics, results and return on investment. Keynote's new approach is tailored to meet these requirements and satisfy multiple audiences from IT to marketing to management.

"As Internet performance becomes faster and more reliable, customers are becoming more concerned with the business value of their operations," said Umang Gupta, chairman and CEO of Keynote. "Enterprise IT managers are under tremendous pressure to do the same amount of work – or more – with smaller budgets and lower headcounts. If a tool does not provide the capability to diagnose problems, it is not perceived as critical to their business. Operational efficiency is a must and tools must be justified by providing a return on investment, otherwise they are not critical to the business."

"With Web Site Perspective 6.0's straight-forward approach to problem diagnosis, everyone in the data center can become instant Keynote experts and quickly find the source of performance problems," continued Gupta. "The new capabilities are all aimed at facilitating collaboration among multiple departments and vendors who are all looking at the same data taken from the same time frame."

What's New in Web Site Perspective 6.0

The following features in Perspective 6.0 facilitate problem notification and diagnosis, leading to faster problem resolution:

• Alarm Enhancements: more informative alerts and alarms; performance and/or availability information; a hyperlink to the alarm data to quickly access the data behind the alarm; new alarm logs sortable by date/time, URL, severity with links to historical alarm data; more frequent alarm cycles calculated every five minutes; user defined warning/critical thresholds and contacts; inclusion of critical markets and maintenance windows.
• Improved Measurement Detail: identify intermittent server and network problems; quickly untangle problems created by the complexity of multiple redirections; diagnostic measurements identify server IP addresses and break down redirections into their individual parts.
• Improved Data Visualization: performance and availability metrics charted in a single view to compare performance to service level objectives; performance and availability metrics compared to user defined thresholds; available for all Keynote performance charts including performance over time, by backbone/ISP, by city and by agent (measurement location).
• Content Error Graph: can be sorted by time, agent, error, server IP address and URL (failed object); pinpoints consistent and intermittent content delivery problems.
• Scatter plot Graph: data visualization and interactive diagnostics in a single view to run diagnostics from the data view; focus on "outliers" to quickly determine if there is any commonality with respect to geography or backbone; quickly compare and analyze historical performance data to current conditions, including DNS, TCP connect time, First Byte time and content download time or errors.

What's New in Transaction Perspective 4.0

Transaction Perspective V4.0, utilizing an embedded version of Internet Explorer, integrates all the new operational and diagnostic features of Web Site Perspective 6.0, while providing a true end-user experience. New features, specifically for customers who need to measure and diagnose performance problems in multi-page transactions, include support for Web services, advanced cookie support for MSN Passport and SSL handshake breakout, as well as end-to-end performance benchmarking and fast diagnosis to correct performance-related problems and reduce time to corrective action

Pricing and Availability

Web Site Perspective 6.0 is available immediately with domestic service plans from $395 to $695 per URL and global service plans from $995 to $1895 per URL.

Transaction Perspective 4.0 will be available in June of 2002. Pricing will start at $995 for US10 per five-page transaction.
