Tumbleweed Bolsters Email Security Products with Addition of Outbreak Detection Publication date: Monday, 23 May 2005 MailGate Email Security Solutions Now Provide Zero Hour Protection Against Spam, Phishing, Email Viruses and Worm Outbreaks Redwood City, CA — May 23, 2005 — Tumbleweed® Communications Corp. (NASDAQ:TMWD), a leading provider of e-mail and file transfer security solutions , announced today that it has extended its comprehensive, industry leading MailGate email security suite with Recurrent Pattern Detection™ technology to enable Outbreak Detection as a new layer of defense against breaking spam, phishing, spyware, virus and worm attacks sent out in email blasts. As reported in the most recent Dark Traffic Report issued by Tumbleweed Communications’ Message Protection Lab, valid email now comprises less than 5-10% of all inbound enterprise message traffic. With the volume and complexity of malicious traffic growing all the time, multi-layer multi-technology approaches have proven to be the most successful at stopping the widest range of known and unknown email threats. The addition of Outbreak Detection to the Tumbleweed MailGate products provides customers with the most effective, complete approach to inbound email security. Tumbleweed’s MailGate suite provides the comprehensive, multi-tiered security framework required to deliver comprehensive protection from inbound email threats: 1. Preventive Defense – These technologies block invalid email traffic in real time using network-level SMTP analysis and traffic shaping, before a message is accepted into the enterprise network. Threats stopped include Dark Traffic, spoofed messages, and invalid recipients. This kind of analysis is generally deployed at the network edge, and can drop anywhere from 50% to 95% of incoming email traffic as junk. 2. Reactive Defense – Once a message is determined to be valid, and is accepted into the enterprise network, Tumbleweed email security applies a number of reactive technologies to block previously identified threats. These include heuristic rules, content signatures, lexical analysis, DNS block lists, and sender reputation service approaches. This layer of defense is used to block traditional spam, phishing, spyware, virus, and worm attacks, with extremely high capture rates and very low false positives. The challenge with this approach is that new, innovative threats that have not yet been analyzed can slip past this layer of defense, which is why a Proactive Defense layer is crucial. 3. Proactive Defense – Proactive technologies complement Reactive approaches by identifying new, emergent email threats in real time, providing true Zero Hour defense. This type of analysis provides near real-time protection against spam, phishing, and virus outbreaks. This approach is particularly strong at defending against zombie attacks sent from hijacked personal computers, which are virtually impossible for traditional sender reputation services to identify. Technologies providing proactive defense include Intent-Based Filtering (IBF), which performs intelligent natural language processing, and Recurrent Pattern Detection (RPD™) which checks each message against Internet traffic to identify outbreaks. In order to combat increasingly sophisticated malicious email attacks, we’re committed to providing our customers with an expanding arsenal of security features,” said John Thielens, CTO of Tumbleweed Communications. “Outbreak Detection, combined with Tumbleweed’s other threat protection technology, ensures that our customers are comprehensively protected from the first minute onward.” The new Outbreak Detection functionality will roll out to existing MailGate Email Firewall customers immediately with the 6.1.1 update, and to existing MailGate AntiSpam Appliance customers in early June with the 2.5 update, free of charge. About Recurrent Pattern Detection (RPD) Spam, phishing, spyware, viruses, and worms are evolving at a frantic pace, and dangerous new spam/malware hybrids continue to emerge. Messages are continuously modified to stay far ahead of rule-based methods, and temporary distribution sources (sender IPs) undermine reputation-based services. Rather than addressing individual messages, RPD technology detects the outbreaks themselves – and blocks all messages associated with them. The most significant advantage of this approach is that it overcomes one of the most pressing issues in the industry: response time to new threats. RPD detects outbreaks as soon as they emerge: the faster an outbreak proliferates, the faster it is identified. Messages associated with mass outbreaks are blocked immediately, with no need to analyze each message. The result is that users are protected in real-time, all the time. RPD is effective against any mailing that is mass-distributed over the Internet: malware, frauds and spam in any language or format.
