Yahoo! Inc. Monday unleashed a major corporate portal initiative which allows companies to offer their employees content and services from the portal giant on in-house networks.

Co-developed with portal technology from TIBCO Software Inc. Yahoo! Corporate Yahoo! is an enterprise information portal based on the My Yahoo! interface.

The two companies created Yahoo! Portal Builder software to enable the integration of customized Internet content delivered by Yahoo! and corporate content from a company's intranets, databases and enterprise applications.

Corporate Yahoo! consists of a highly personalized portal where employees can pull up financial news, human resource news, stock quotes and a slew of relevant information released by their firms.

Yahoo! inked a number of technical and content alliances en route to rolling out the latest major enterprise strategy, a sector that Merrill Lynch predicts will climb from $4.4 billion in 1998 to $14.8 billion in 2002.

The first clients to deploy Corporate Yahoo! include Alcatel, Inktomi Corp. and Network Appliance.

In addition to soliciting TIBCO for portal solutions, Yahoo! has called upon Hewlett-Packard Co. will act as a premier reseller and will also provide sales, marketing, system integration and customer support.

Inktomi Corp., Yahoo!'s default search provider for the last two years, will provide premier search and navigation technology. Ironically, Inktomi was replaced Monday as the portal giant's default search provider by Google.com which released what it claims to be the world's largest search index.

Yahoo! has also developed alliances with the following technology solution providers to boost the quality of Corporate Yahoo!'s service:

• Citrix Systems' NFuse technology will enable server-based applications to be launched from a standard Web page simply by clicking on a link or icon
• Netegrity's SiteMinder secure management platform will enable single sign-on, authentication management and entitlement management
• Critical Path will support messaging, personal information management and collaboration through its InLine Resource Management, InSchedule Calendaring, InScribe E-mail Messaging and InScribe Secure File Services

"Corporate Yahoo! will help Global 2000 companies maximize the investment they have already made in their intranets and extranets by providing a compelling service for accessing both corporate and personal information," says John Willcutts, vice president, Yahoo! Enterprise Services.

"We have developed this solution in response to strong demand from companies that want to leverage Yahoo!'s current popularity in the workplace to increase productivity and improve communications."
