Global Internet Performance Conference (GIPC) East

NEW YORK--(BUSINESS WIRE)--Oct. 28, 2002

First Ever Global Internet Performance Conference East in NYC;

Five New and Updated Services Announced, One Previewed

Against a backdrop of hundreds of IT professionals focused on optimizing the experience of online users, Keynote Systems(TM) (Nasdaq:KEYN) today held its first ever Global Internet Performance Conference East in New York City. The event is an opportunity for Keynote to educate IT executives on 'best practices' in Web performance management, and continue to showcase its 'Total Performance Management' strategy unveiled at GIPC West held in June in San Francisco.

Keynote delivered on the TPM promise today with the announcement of five new or enhanced services, one based on the acquisition of Enviz called Keynote WebEffective(TM) (see separate press releases issued today), and the preview of an exciting new service dubbed "MyKeynote(TM) Inside," that for the first time brings a real-time feed of Keynote's Web performance data directly into the network operations centers large enterprise businesses use to monitor and manage all their information-based systems.

In testing and diagnostics Keynote announced WebEffective, Enterprise HTML Toolbox and Test Perspective(TM) 5.0:

-- WebEffective is a brand new service based on the acquisition of Enviz, the leader in user experience testing technology. WebEffective is a testing service for diagnosing and improving Web effectiveness by testing the total quality of user experience, capturing everything the user sees and does: how users interact with pages, how users navigate (including back and forward buttons), where they encounter difficulty with navigation, why they do not complete key business processes, and whether their needs are met. Questions may be asked, in context, of users to diagnose reasons for user actions. The new service is offered as a full service or self-service appliance-based solution.

-- Enterprise HTML Toolbox is a new self-service, Web site content and integrity testing service developed to meet the needs of enterprises operating large Web sites. The Enterprise HTML Toolbox now adds an additional layer of testing functionality to Keynote's testing solutions, providing self-service content testing. The Keynote Enterprise HTML Toolbox is delivered via an appliance that resides in a customer's data center and can test public or private (i.e. Intranet content, content on staging servers) sections of the Web site. It provides link integrity testing, HTML standards conformance testing, browser compatibility testing, image load time optimization and spell check.

-- Test Perspective is an updated version of Keynote's self-service Web site load testing solution that delivers increasingly accurate and realistic load test results using new ground-breaking `arrival rate' methodology and a more powerful script recorder. The updated version also introduces much more flexible hours-based pricing and packaging to meet the dynamic and changing needs of customers and partners.

In benchmarking and application performance management Keynote announced Traffic Perspective(TM) and Keynote Diagnostic Services:

-- Traffic Perspective is a new service that combines passive

monitoring of real-time end user traffic with data collected

by Keynote's benchmarking services to create a unique

non-intrusive solution to quantify, isolate, diagnose and

resolve Web performance issues. The new service brings

together business level metrics about real end users with

system and application response information and offers two-way

integration between Keynote and partner products (Adlex and

Emissary to start). The service marries together for the first

time and 'in context' a graphical real-time view of active and

passive monitoring data. Traffic Perspective is designed to

quantify the performance impact of traffic volume, network

conditions, server performance and visitor abandonment.

-- Keynote Diagnostic Services is a new Keynote service that

provides interpretive services, diagnostic tools and

expertise, proactive performance monitoring of alerts and

immediate remediation, and customer advocacy with service

providers and others on behalf of Keynote customers.

Keynote is the clear benchmarking market leader with over 80% market share and the world's largest distributed infrastructure of measurement computers that provides customers with the most representative and accurate benchmarking data available.

"With our many announcements today Keynote is deepening and broadening its Web performance management services for solving specific e-business performance problems. WebEffective and Enterprise HTML Toolbox take Keynote in the new direction of user experience testing and content integrity testing, two areas critical to optimizing the quality of e-business," said Umang Gupta, chairman and CEO of Keynote. "In tough times we believe it's better to help customers run existing business solutions better, rather than attempt costly architectural changes to them. Every one of our services announced today helps enterprise companies leverage what they already have so they can do more with less.
