Our ISP customers constantly tell us that outbound spam is the biggest operational headache they face. Each week they spend countless hours getting off blacklists and chasing down compromised accounts or spammers on their networks. With Commtouch’s new solution, our ISP customers will instantly identify and stop zombie and intentional spammers, so they can keep their customers’ mail flowing, preventing them from being blacklisted and maintaining their reputations.
Customer loss, damage to service provider’s’ reputation and brand, operational cost increases and even potential lawsuits are just some of the possible consequences service providers face as a result of spam, malware and phishing emails emanating from their networks. Commtouch’s Outbound Spam Protection solution not only enables service providers to stop these unwanted emails but also provides immediate identification of the sender. This enables appropriate management of the source of the problem, and not only the symptoms.
Because the problem differs significantly from that of inbound spam, the potential hazards of outbound spam require a distinctive approach to protect service providers against this rapidly growing threat. Patchwork solutions such as blocking port 25 and employing standard inbound anti-spam filters on outbound traffic results in very high false positives and frustrated users.
Commtouch has specifically tailored a solution to properly address outbound spam, malware or phishing. The solution also detects any type of outbound spam source, including zombie computers, compromised accounts, spammer accounts and webmail spammers.
A small, efficient local engine installed at the service provider’s network implements the same patented Recurrent Pattern Detection™ (RPD) technology used in Commtouch’s cloud-based detection centers to analyze local service provider traffic, detecting outbound spam within seconds with almost no false positives. The service provider receives the sender address as well as samples of the blocked emails for analysis.
