Micromuse Inc. (Nasdaq: MUSE), the leading provider of ultra-scalable, realtime business and service assurance software, today announced that the German Commerzbank Group has deployed the Netcool/Precision(TM) suite of applications to more efficiently manage the service infrastructure across its retail and commercial banking departments. Commerzbank is one Germany's largest private-sector banks with subsidiaries in 43 countries worldwide.

"Commerzbank has more than seven million customers worldwide," said Zeljko Smetko, Vice President Data Services International at Commerzbank. "The bank's IT infrastructure is very complex. It generates massive volumes of event data, and we needed to centralize, correlate, and analyze all of the event data from our trading infrastructure. Netcool solutions provide a flexible platform to implement security, service level, incident and inventory management across an entire network and that is why we at Commerzbank chose it."

Prior to deploying the Netcool suite, Commerzbank was using the Micromuse's Riversoft NMOS technology for root cause analysis and topology mapping of its IT infrastructure. Commerzbank selected Micromuse's Netcool solution in part because of the NMOS technology's ability to integrate seamlessly with the Netcool(R)/Precision(TM) product family. Additionally, the end-to-end Netcool solution deploys rapidly and offers off-the-shelf integrations with existing components, services, and applications across Commerzbank's IT infrastructure. Netcool solutions collect, filter, classify, and visualize status information from Commerzbank's infrastructure in realtime and provide the bank's operations teams with auto-discovery, topology mapping, and root cause analysis.

"Commerzbank considers its network infrastructure the essential foundation for delivering the secure, robust services that its customers expect from a reputable financial institution," said Richard Lowe, Micromuse's Senior Vice President for Europe, the Middle East & Africa. "Micromuse's Netcool solution has been deployed at leading global financial institutions since 1999, and we have many years experience at delivering the robust, secure platforms to support high volume, high value transactions 24 hours a day."
