Tumbleweed Builds Momentum in North America with Premier Channel Partners

Tumbleweed® Communications Corp. (NASDAQ: TMWD), the industry's leading pure play messaging security vendor, today announced major expansion in its Tumbleweed Alliance Program (TAP) with the signing of several reseller leaders in the North American channel. Fishnet Security, Midwave Corporation, Cadre, Accudata Systems, ESI Information Technologies Inc., and Choice Solutions have all joined Tumbleweed as leading resellers, opening new vertical markets including retail, manufacturing, energy, transportation and education for the messaging security leader. Today’s announcement underscores the company’s significant momentum in the channel and comes on the heels of recent key sales appointments and several new channel partners in the Asia Pacific region. On a global basis, Tumbleweed is rapidly enabling qualified security resellers to sell Tumbleweed’s managed file transfer, email security and identity validation products. Tumbleweed’s new North American TAP partners are deploying hundreds of new professionals selling Tumbleweed products in North America. "Tumbleweed has an exceptionally strong track record in the enterprise space, which makes them a natural fit for our clients,” said Jim Leslie, CEO of Midwave Corporation. "Their highly differentiated managed file transfer products will enable us to go deeper and broader with our existing customers – and their product roadmap shows tremendous promise for future revenue growth.” Currently, Tumbleweed offers leading security products, largely in the financial, health care and governmental markets, supporting 8 of the top 10 financial institutions and all four branches of the U.S. armed forces. The TAP expansion has been driven by strong demand for innovative, reliable and easy-to-use messaging security solutions into new verticals ripe for these products. According to Gartner, messaging security represents a $2.9 billion market opportunity by 2009. "Partnering with Tumbleweed allows us to meet our customers’ needs with the strongest suite of messaging security solutions in the market – spanning managed file transfer to email to encryption,” said Jim Steinlage, president of Choice Solutions. "Tumbleweed considers us a true partner and provides unparalleled TAP support. Their best-of-breed products, exceptional programs and strong margins will fuel our success. They even have a program that enables us to promote greater revenues through professional services.” Meanwhile, rapid consolidation and acquisition in the messaging security industry is squeezing some channel programs. Tumbleweed has made a sizeable investment in growing a differentiated program and a long-term commitment to driving channel success. "We have signed industry leaders among security resellers, a move that will fuel significant adoption of Tumbleweed’s highly differentiated products,” said Nick Hulse, executive vice president of Worldwide Field Operations. "In particular, our managed file transfer products will drive significant growth and profitability for our partners, and we are delighted to support their success.” Not Another "Me Too” Channel Program Tumbleweed has attracted top-tier resellers with a channel program that is innovative and distinguished from the rest.
