(Nasdaq: SUNW - news) today announced it will rebrand its popular iPlanet, Forte, StarOffice and Chili!Soft product lines under the Sun Open Net Environment (SunONE) brand. This move reflects Sun's commitment to its wide array of software offerings -- spanning from portal server and middleware to directory solutions, developer tools and productivity suites -- that make up the Sun ONE platform for Services on Demand. Branding all of the products under the Sun ONE name will result in a singular focus that simplifies Sun's software portfolio for customers and streamlines marketing efforts.

"This rebranding is the culmination of what we've been successfully doing for the last several years -- delivering best-of-breed and integrated product solutions for the enterprise," said Marge Breya, vice president, Sun ONE. "It's time for our software brand to reflect what our customers already know; there is no more complete, secure and productive platform for making the net work than Sun ONE."

Sun has launched a global marketing campaign to support the rebranding effort that will kick off this week with a series of print advertisements scheduled to appear in major business publications. The advertisements feature Sun's Global Fortune 500 customers and will highlight how they are investing in Sun technology to provide superior cross-business integration, improve cost efficiencies and enable them to build a web services infrastructure that will deliver higher Return on Assets.
