Webroot Selects Mailshell's LiveFeed to Provide Reputation-Based Security

Webroot® Email Security SaaS to Provide Additional Protection from Spam, Phishing and Email-Borne Threats

BOULDER, CO - May 7, 2008 - Webroot, a leading provider of security solutions for the consumer, enterprise and SMB markets, today announced the integration of Mailshell's LiveFeed reputation service to provide additional protection from spam, phishing and other emerging email-borne threats. The first deployment of Mailshell Engine for Webroot will be in Webroot® E-mail Security SaaS, but Webroot has also licensed the technology for use in its other product lines and will join more than 6,000 companies and 15 million consumers relying on the technology to protect them from spammers and phishers.

"Over the coming year, each business email inbox will be hit with over 42,000 spam messages. Webroot's goal is to filter spam and phishing attempts in the cloud to keep company networks as clean as possible. We tested several new reputation technologies and were impressed with Mailshell LiveFeed's speed, accuracy and ease of use. With their advanced statistical modeling techniques, Webroot will continue to re-define 'enterprise-class'," said Mike Irwin, COO of Webroot. "By delivering this substantial new capability in our security software-as-a-service offering, customers will immediately be able experience the advantages of this capability without the costly and slow process of upgrading appliances and on-premise software solutions."

E-mail spam can account for over 95 percent of a company's daily e-mail traffic. Viruses transported via spam are a top security concern for SMB and enterprise technology decision makers. Managing these concerns translates into a significant investment in time and money for IT departments.

Webroot E-mail Security SaaS alleviates these concerns by utilizing a multi-layer approach to spam filtering that includes careful attention to connection management and integration of multiple best of breed filters to block the maximum quantities of spam with the lowest possible rate of false positives. In all, Webroot E-mail Security SaaS catches 100 percent of all known viruses, provides zero-hour protection against unknown viruses via advanced heuristics and filters 98 percent of all spam. And, it delivers this better level of security with better support and better manageability.

In addition, the combined solution is the first one specifically designed to quantify reputation via advanced statistical models. Unlike other reputation services that provide only a binary 'good' or 'bad' rating, Webroot E-mail Security SaaS can now provide granular trust ratings with automated adjustment over time as reputations change. By focusing reputation on mathematical models, rather than simply a 'black list' approach, language-agnostic detection can be more accurate and highly scalable.

LiveFeed also helps Webroot E-mail Security SaaS provide greater detection of spam bots by identifying servers connecting to public mail servers against the IP owner's terms of use. Additional anti-spam capabilities include the tracking and updating of reputations in real-time via data collected from spam traps, OEM partners uploading anonymous data statistics from applications, a collaborative end-user network, and data sharing partnerships.

"Webroot has demonstrated its commitment to building and sourcing the best forms of protection for its customers," said Tonny Yu, CEO of Mailshell. "Its use of multiple, complementary techniques ensure its customers are protected both from existing attacks as well as new, unforeseen threats."
