ZEROSPAM, Parus Interactive and B2B2C Successfully Deploy Cloudmark Authority for SpamAssassin to Provide Carrier-Grade Spam, Phishing and Virus Protection; Cloudmark Launches Free Trial Program for SpamAssassin Users

San Francisco, June 18, 2007 – Cloudmark, Inc., the global leader in carrier-grade messaging security, today announced that ZEROSPAM, Parus Interactive and B2B2C have successfully deployed Cloudmark AuthorityTM for SpamAssassin, giving subscribers the industry's fastest and most accurate spam, phishing and virus protection. The addition of these leading independent service provider organizations to Cloudmark's customer base reflects the company's continued momentum among mid-market service providers. Cloudmark's solution has already been proven in the most demanding messaging environments. In the past year, seven of the top 10 ISPs/carriers in North America have selected Cloudmark Authority to protect more than 180 million mailboxes from messaging abuses.

SpamAssassin is an open source platform for email filtering that is already deployed in more than 100,000 organizations. Utilizing a unique combination of Advanced Message Fingerprinting and real-time corroborated feedback from the Global Threat Network, Cloudmark Authority for SpamAssassin rapidly detects messaging abuse with more than 98 percent accuracy and near-zero false positives. In addition, by requiring only a fraction of the processing power of alternative solutions and automatically distributing the latest threat definitions every 45 seconds, Cloudmark Authority for SpamAssassin frees IT resources and reduces administrative time while delivering the highest level of protection against new threat outbreaks.

Cloudmark Authority for SpamAssassin Customers Experience Immediate Results

ZEROSPAM is a leading managed email filtering service launched in Montreal in 2003 that was developed specifically to eliminate email-related threats and nuisances, such as spam and viruses, from messaging systems. Today, more than 200 clients from the public and private sector, including a score of prestigious organizations representing thousands of mailboxes, are taking advantage of the ZEROSPAM service.

"Image spam has been a significant challenge for us and the global anti-spam community over the last six months," said David Poellhuber, ZEROSPAM founder and CEO. "After evaluating several different providers, Cloudmark Authority for SpamAssassin came out far ahead of the pack with impressive efficiency in blocking all forms of messaging abuse, from simple nuisance spam to phishing attacks to complex images embedded with malicious code, and with no false positives. Integration of Cloudmark's solution into our messaging infrastructure was a snap--we were up in a matter of minutes and our customers noticed an improvement in detecting and blocking image spam right away. With Cloudmark, we can be certain that a spam campaign originating in Asia at 1:15 in the morning is detected at 1:16 and blocked at 1:17. Cloudmark Authority for SpamAssassin was really the ideal complement to our multi-layer filtering architecture."

Parus Interactive is the nation's largest hosted unified communications provider, with tens of thousands of customers relying on it to easily send and receive emails, phone calls and faxes through a single phone number. A leading applications service provider, Parus also offers email and voice messaging, audio and video conferencing, interactive voice response (IVR) and virtual assistant communications services to a diverse range of enterprises and small business customers.

"As host to thousands of mailboxes, we are focused on ensuring the highest level of protection for our subscribers against a growing universe of email-borne threats," said Keith Fenech, vice president of engineering & operations, Parus Interactive. "Despite staying current with the latest rulesets and recommended configurations on SpamAssassin, we quickly realized that our customers were still being inundated with spam. Cloudmark Authority for SpamAssassin was the perfect choice for us, delivering the industry-leading accuracy and performance we needed with seamless integration into our existing messaging infrastructure. It took us just one hour to download and implement and we saw filtering rates jump from 50-60 percent to more than 95 percent almost immediately. The result has been a precipitous drop in spam and junk mail making its way into our customers' inboxes, which makes them, and us, extremely happy."

These results are echoed by B2B2C Inc., who began using Cloudmark Authority for SpamAssassin in early 2007. "Cloudmark Authority for SpamAssassin enables us to easily integrate Cloudmark Authority into our legacy messaging system without the need for additional development or tools," said Martin Lathoud, system administrator for B2B2C Inc. "The powerful combination of SpamAssassin's email filtering with Cloudmark's Advanced Message Fingerprinting technology has lowered CPU utilization and reduced the incidents of false positives, making a huge difference in the cost of ownership and overall customer satisfaction."

"Following on the heels of our success in the Tier 1 ISP market, Cloudmark has focused on helping mid-market and independent service providers like ZEROSPAM, Parus Interactive and B2B2C dramatically improve the quality of service offered to their subscribers while also optimizing infrastructure efficiency," said Jacinta Tobin, vice president of worldwide sales and business development at Cloudmark. "These smaller organizations have voiced a clear need for the same level of security and processing efficiency as their Tier 1 counterparts, but can ill afford major infrastructure changes, additional administrative burden or expensive integration. Cloudmark Authority provides independent ISPs using SpamAssassin with a pre-built solution that delivers the most accurate and cost-effective content filtering available today. The rapid adoption we have experienced over the past few months is a clear indication that our solutions are hitting the mark."
