Recurrent Pattern Detection adds outbreak detection as an additional layer of defense against spam, phishing, spyware, virus and worm attacks sent out in email blasts. It is a strong complement to our comprehensive email security offering. Outbreak Detection, combined with Tumbleweed's other threat protection technology, ensures complete protection from increasingly nefarious email attacks. 
With spam and malware comprising the majority of all email, enterprises and service providers face bloated IT costs, and deterioration in the quality of service for valid traffic. Commtouch's GlobalView™ Mail Reputation Service fights unwanted mail at the perimeter, reducing more than 85% of incoming messages at the entry-point, before these messages enter the network. Additionally, GlobalView can optimize traffic flow so that legitimate sources gain optimal access, while unauthorized sources attempting to abuse the network are blocked.
GlobalView differs from other similar-sounding services in terms of its unique breadth of coverage, and its analysis and delivery of information in real-time. Built on Commtouch's comprehensive view of global Internet traffic, GlobalView distinguishes in real-time between legitimate corporate senders, valid publishers, zombies, and spammers/malware distributors.
Commtouch global detection centers analyze more than two billion Internet transactions per day, providing visibility into network traffic in every location around the world. This critical mass of data is analyzed using Commtouch's patented RPD technology, enabling the real-time delivery of IP address classification. GlobalView determines if a particular address is sending spam and/or legitimate email, and if it has been compromised into a zombie. These capabilities enable the GlobalView service to block distributed attacks the moment they start.
Many public services deliver free information about blacklisted sources. Some services even enable setting central and personal policies for whitelisting during the SMTP session. However, these solutions are not designed to handle the ever-changing sender landscape, where zombies can be activated and de-activated at a moment's notice. Commtouch's global collection network analyzes over one billion messages every day. Included in this analysis is a process whereby Commtouch dynamically classifies and reclassifies the reputation of each source IP with a series of meaningful and measurable values that is constantly updated to include the most up-to-date information and reflect even the slightest change in credibility to meet the requirements of every messaging, security and networking vendor.
Commtouch GlobalView Mail Reputation classifies traffic in real time, based on these and other factors:
The built-in Decision Manager module captures all of the inputs of the GlobalView service, combines it with data particular to the local implementation, and computes a recommended action using advanced flow control algorithms. In this way accurate blocking decisions can be made, keeping unwanted traffic out, and clearing the way for legitimate traffic.
