Deploy Robust Botnet Security with Intelligent Edge Defense

MailGate Intelligent Edge Defense module combines anomaly detection and rate throttling with real-time zombie detection and IP reputation services to provide an effective defense against distributed botnet attacks. This unique combination of capabilities correlates and identifies spam outbreaks across multiple IP addresses, even if they have been recently hijacked and have no existing negative reputation.

The Intelligent Edge Defense module reduces raw email loads by more than 90 percent by eliminating directory harvest attacks, email denial-of-service attacks, malformed SMTP packets, invalid recipient addresses, and other forms of malicious and invalid messages. And by verifying valid recipients at the perimeter, MailGate enables you to create IP-based block and allow lists, identify suspicious senders, and apply intelligent traffic shaping and message throttling for invalid messages.

MailGate’s Domain Keys Identified Mail (DKIM) technology authenticates user email domains to ensure senders are who they say they are within an organization. Bounce Address Tag Validation (BATV) is a powerful antidote to the recent proliferation of non-delivery email attacks, in which spammers spoof individual email addresses for use in spam activities.
