Expert advisers to growing businesses, BDO Stoy Hayward, recently featured in the Growth Company Investor's published list of Top 50 Movers and Shakers, selected Interliant, Inc. (Nasdaq:INIT), a leading global application service provider (ASP), to host, manage and maintain their corporate Web site. The Web site provides clients with 24-hour access to information about BDO Stoy Hayward and their services

The re-launch of the Web site is part of BDO Stoy Hayward's continuing focus on the e-business arena. It forms part of a deal in which Interliant will host all of BDO International's client extranet sites globally.

The 24-month contract calls for Interliant to provide BDO Stoy Hayward with a fully managed dedicated Domino hosting solution hosted in Interliant's London data center. As part of the contract, Interliant also will deliver a full information-backup service along with 24x7x365 support. The Web site will be protected by a managed firewall solution to prevent unauthorized access or site defacement.

"The BDO Stoy Hayward Web site plays an integral part in communicating to existing and potential customers," said an official spokesperson at BDO Stoy Hayward. "BDO Stoy Hayward offers a broad service range to support entrepreneurial businesses on the challenges they face. We needed a central repository where information about the company and its activities could be reliably and securely communicated. This Web site communicates BDO Stoy Hayward's brand to the outside world, and we needed a partner who could reliably deliver something so core to our brand awareness efforts. Interliant's customer focus and proven track record combined with 24-hour support and security was precisely the solution we sought."
