Ensim Unify to Help Siemens Provide Managed IT Services for Small to Medium-Size Businesses

Sunnyvale, Calif., March 9 , 2005 - Ensim Corporation, the global leader in hosting automation software, today announced that Siemens Solution1 selected Ensim Unify as the hosting automation platform for its messaging and collaboration offerings. With Ensim Unify, Siemens is able to effectively offer Exchange 2003, Windows SharePoint Services and additional add-on email solutions as hosted services. The company will migrate current customers over to the Ensim Unify platform, and will be targeting new small and medium-size business (SMB) customers with an offering that includes full-featured Exchange 2003 MAPI mailboxes, anti-SPAM, and Outlook Web Access.

The Ensim Unify solution offers robust extensibility features that enable Siemens to integrate key service add-ons such as anti-SPAM, as well as plan for additional future service add-ons such as mobility and archiving. One key component of the Siemens Solution1 offering will be an end-customer self-management portal. Designed with comprehensive integration frameworks, Ensim Unify provides robust APIs for building custom interfaces.

According to Jonathan Evans, Head of Marketing for Siemens Solution1, “Microsoft recommended Ensim, and upon evaluation of the Ensim Unify solution we were confident that they were the right partner for managing and delivering hosted services. Ensim brought a deep expertise in Hosted Exchange 2003, and their technical team was with us every step of the way in implementing a complex solution. Most importantly, Ensim understands the need for differentiation and designed their platform with extensibility in mind to help us meet the needs of our ever-changing market.”

Micheline Germanos, director of Microsoft Hosting EMEA, commented "Siemens Solution1 addresses the needs of Small Businesses for hosted services supported by a streamlined networking and datacenter solution. Ensim Unify is well-positioned to meet Siemens’ requirements for an open, extensible platform for Windows-based messaging and collaboration.
