Mazars Goes Live with Tumbleweed’s Managed File Transfer Solution to Scale Business Operations

London, UK - September 26, 2007 - Tumbleweed® Communications Corp. (NASDAQ:TMWD), an industry leader in managed file transfer and content security, today announced that Mazars, the international accountancy and advisory firm, has gone live with its managed file transfer solution, SecureTransport™. The solution’s scalable and single platform will enable Mazars to enhance its customer service by sending and receiving electronic documents securely over a variety of open standard protocols while continuing to boost its customer base.

As Mazars exchanges highly sensitive and valuable information with its large, global financial services clients, its existing security solutions were becoming too complex and outdated to meet its transaction reporting needs. Mazars required an open-standard, industrial strength security solution sitting at the perimeter of its organisation to provide a single point of administration and enforcement of its security policies in this area. Leveraging the existing technology, it was critical that the chosen solution could meet the strategic objectives and support the existing customer base while facilitating the adoption of new customers.

David Cross, Director of IT at Mazars, said: “With our clients, a ‘one size fits all’ approach won’t work – flexibility and scalability are extremely important in the choice of a managed file solution.  Tumbleweed’s solution enables us to streamline the reporting processes and this has eased our operational burden.  It also means that we can enhance services to existing customers and still be flexible enough to continue providing a customised service to new ones.  Having SecureTransport in place to manage, link and audit transactions means that we can scale our IT resources more efficiently as the business grows.” 

Mazars selected Tumbleweed’s SecureTransport following an in-depth evaluation process. Not only does the solution provide the most secure, reliable, manageable and auditable file exchange, Tumbleweed’s experience and expertise of managed file transfer within the financial sector was also a deciding factor for Mazars. Tumbleweed products are used by at least 8 of the top 10 U.S. banks and leading UK banks.

Craig Whitney, Managing Director of EMEA at Tumbleweed, said: “Many organisations like Mazars come to us with the issue of a complex home-grown file transfer infrastructure that no longer corresponds to their needs. With SecureTransport, organisations can leverage their IT investment because the solution easily integrates with the existing IT infrastructure.  The solution will enable IT Administrators at our customers, including Mazars, to gain control of multiple and diverse departmental file transfer solutions while ensuring application reliability, maintaining end-to-end security, and keeping IT costs in check.”
