TMWD Tumbleweed Communications Corp (MM)

Tumbleweed(R) Communications Corp. (NASDAQ:TMWD), a leading provider of email security, managed file transfer, and identity validation appliance and software products, today announced that it has received a "Positive" rating in the latest Gartner MarketScope Email Encryption report. To view the entire report, please visit: http://www.tumbleweed.com/products/mailgate/gartner_marketscope.html "We are very pleased to receive a 'Positive' rating in this Gartner MarketScope report. We feel these findings confirm that Tumbleweed continues to provide one of the industry's most effective e-mail security solutions available," said John Thielens, CTO of Tumbleweed Communications. "Our mission is to provide the best e-mail security tools possible to meet the challenges of data privacy protection, regulatory compliance, and protection of intellectual property for our customers. We are excited to be recognized by Gartner for our efforts." This MarketScope report focused on a specific e-mail encryption market -- the gateway encryption market, in which no desktop software is required by sender or receiver. Gartner continues to see the majority of user demand for specific solutions in this market. Gartner states that gateway e-mail encryption is an emerging security market estimated at less than $40 million to $50 million in revenue worldwide at this time. According to the Gartner report, within this space, vendors that offer e-mail security functionality -- such as spam, antivirus and content filtering -- and e-mail encryption, and that also possess more extensive resources from a large existing enterprise installed base, which they can sell e-mail encryption to as an add-on functionality, are best-poised for longer-term viability. Gartner reviewed a total of seven email encryption vendors in the report, basing results on criteria including customer experience, market understanding and product strategy, as well as other criteria. Gartner defines a "Positive" rating as meaning that a vendor has demonstrated strength in specific areas, but is largely opportunistic and recommends that existing customers continue incremental investments, while potential customers should put this vendor on a short list of tactical alternatives.
