Tumbleweed Mailgate Edge

Secure Email Relay and Defense Against “Dark Traffic”

Dark Traffic, which currently represents up to two thirds of all inbound port 25 traffic, is comprised of a combination of spam, spam precursors like directory harvest attacks (DHA), email denial of service (DoS) attacks, malformed SMTP packets, invalid recipient addresses, and other requests and communications unrelated to the delivery of valid email messages. MailGate Edge™ is a secure email relay that delivers state-of-the-art network-based email defense against these threats at the edi gateway.

With MailGate Edge, organizations can:

• Detect and prevent DoS and DHA attacks
• Control inbound connections
• Control SMTP errors
• Verify recipients before they enter your network
• Create IP-based block and allow lists
• Cut inbound traffic and load instantly
• Significantly reduce costs by optimizing network performance and eliminating the need for costly email server upgrades

By looking at the sender IP-address, number of connection attempts, message volume, recipients, and other attributes across SMTP connections, MailGate Edge is able to identify network-level patterns consistent with email security threats and take appropriate defensive action. For example, DHAs generally come from one or a few IP addresses, and send a disproportionately high number of messages with invalid recipients. DoS attacks typically try to establish a very large number of connections, or send a very large number of messages over a small number of connections.

MailGate Edge runs on a simple-to-manage Linux-based appliance that is tuned for high-volume message transfer. This network--level approach provides significant security without the processing bottlenecks caused by content-centric email hygiene gateways, plug-ins, and filters. Organizations can easily scale MailGate Edge to handle large email volumes by deploying multiple MailGate Edge appliances using MX round-robin techniques or a load balancer.

Complete Protection Against Dark Traffic, Right out of the Box

MailGate Edge delivers state-of-the-art defense against network-level email attacks in a simple-to-manage Linux-based appliance Key features include:

An intuitive Web-based administrative user interface offers point-and-click configuration and graphical reporting right out of the box, significantly reducing the time and costs associated with managing your relay. Seamless LDAP/Active Directory support further streamlines management. Integration with your existing email architecture enables MailGate Edge to leverage routing, connection, and authentication information to identify and defend against a variety of email attacks, giving your organization more protection with fewer resources.

Scalability up to very high levels of throughput and the option for redundant configurations improve the overall reliability of your email network. Because MailGate Edge allows you to securely process email in the DMZ, large volumes of inbound junk email never enter your corporate network. This reduces the overall amount of inbound email and allows your anti-spam and anti-virus processes to occur behind the DMZ.
