TMWD Tumbleweed Communications Corp (MM)

Tumbleweed� Communications Corp. (NASDAQ:TMWD), the industry�s leading pure play messaging security vendor, today announced the availability of its newest MailGate� messaging security appliance and Validation Authority (VA) identity validation appliance, both setting performance benchmarks in their respective fields. The newest MailGate appliance is able to process up to 1.8 million messages per hour, a new messaging security performance standard and substantial performance advantage over competing appliances. The Tumbleweed Validation Authority� identity validation appliance, used for real-time validation of digital certificates, has now increased appliance performance by up to 40 percent. The enhanced performance of Tumbleweed�s newest MailGate appliance enables enterprises to remain ahead of the recent increase in spam volume and size, due to larger image spam messages. Companies can also use MailGate to efficiently perform outbound content filtering to protect intellectual property and other sensitive data. Validation Authority�s performance gains will now allow banks, government agencies, and businesses around the globe to even more effectively utilize their Public Key Infrastructure (PKI) and digital certificates to secure access to networks, electronic transactions and physical access of military and government facilities. �We are releasing two high-performance appliances to counter the recent doubling of worldwide spam volumes and need for content filtering, along with our insistence on offering the fastest possible VA appliance�, said Joe Fisher, vice president of product management at Tumbleweed. �Tumbleweed recognizes the need for constant innovation to remain ahead of threats and exceed customer expectations, so these new appliances set new standards amongst competing products that will enable our customers to remain secure and focus on their core businesses.� To enhance MailGate�s performance, Tumbleweed has incorporated sophisticated dual-core processors, redundant drives with RAID controllers, and embedded systems-management processors for remote serviceability into the MailGate line. Tumbleweed has also further enhanced its worldwide support levels with same-day, onsite service for any hardware issues that may arise. �Businesses need to stay ahead of the ever-increasing amount of spam, which increased some 100 percent between May 2006 and January 2007,� said Michael Osterman, president of Osterman Research. �By constantly improving product performance and placing an emphasis on innovation, companies like Tumbleweed enable businesses to retain control of their messaging security and data protection." The MailGate performance advancements come on the heels of two SC Magazine honors for the MailGate line, both an SC Magazine Best of 2006 Award and finalist honors for the SC Magazine Excellence Awards.
