Concord Announces Siebel Validation - Successfully Integrates Business Service Management Software with Siebel Business Applications.

MARLBORO, Mass. -- End-to-End Approach to Application Management Assures High CRM Performance Levels and Identifies and Resolves IT Issues Prior to Business Performance Being Compromised

Concord Communications, Inc. (NASDAQ: CCRD), a global provider of Business Service Management (BSM) software solutions, today announced that the integration between its BSM software and Siebel 7 and 7.5 has been successfully validated by Siebel Systems, Inc. Siebel Systems is a leading provider of business applications software. In February, Concord joined the Siebel Alliance Program as a Strategic Software Partner and began working toward this important integration milestone. Concord is currently working toward validation on Siebel 7.7.

Siebel Systems provides organizations with a proven set of industry-specific best practices, CRM applications software, and business processes, enabling corporations to sell to, market to, and service customers across multiple channels and lines of business. Concord's BSM solution for Siebel business applications assures the performance and availability of the critical business processes delivered by Siebel applications. Leveraging Concord's eHealth(R) Suite, the newly validated solution optimizes IT services to drive business success, delivering the end-to-end visibility and management necessary to assure that companies get the most from their Siebel investments.

Concord's eHealth Suite for Siebel business applications maps business processes to the IT infrastructure, measures the actual end-user experience, and manages the applications, systems and networks that end users rely on to do their jobs. While Siebel Service Analytics shows how well the internal users and call center agents are performing, Concord's eHealth Suite tracks how well the Siebel business applications, systems, and networks are performing to support those users. This end-to-end approach to application management assures that performance levels remain high and that IT issues can be resolved before they affect the business.

"Partnering with Siebel Systems supports our vision to provide large enterprises and service providers with a single, comprehensive view of their business services - including their applications, systems, and networks - from the perspective of the end user," stated Dayton Semerjian, Executive Vice President of Marketing and Strategic Alliances for Concord Communications. "With the successful integration of Concord's Business Service Management solutions with widely-deployed Siebel business applications, joint customers are able to tie the behavior of their Siebel applications to the underlying infrastructure and proactively identify and troubleshoot problems before business performance is compromised. Concord's strategic partnership and validation with Siebel 7 and Siebel 7.5 demonstrates our commitment to deliver on our BSM strategy, enabling organizations to assure the highest possible performance from their packaged applications."

"Siebel's partnership with Concord addresses the needs of our customers, including the ability to assure the performance and availability of critical business processes," said Craig Crawford, Group Director, Alliances for Siebel Systems. "Through this partnership, our joint customers will have a more accurate view of their IT infrastructure performance and realize a competitive advantage by being able to better service their end-users."

Siebel Systems forms alliances with proven technology leaders to deliver tangible business benefits throughout the enterprise. By choosing Siebel business applications and validated partner solutions, Siebel Systems' customers can pursue a best-of-class software acquisition strategy. The Siebel Validation Program applies rigorous technical scrutiny to evaluate the integration of third-party solutions with Siebel business applications. Integrations that meet the strict testing criteria are validated and documented by the Siebel Validation Program. Validation documentation is available on the Siebel Partner Directory at www.siebel.com/partners/dir/directory.shtm.
