"Dark Traffic" currently represents up to 70% of all inbound email traffic. It is made up of spam, 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. With most solutions available today, it is quite difficult to identify and block these kinds of email security threats. And the deeper these messages get into an organization's email network, the greater the cost and the higher the security risk. This Dark Traffic Email Report defines and analyzes dark traffic email gathered through a combination of research interviews with enterprise IT and email administrators in the US, and taps of raw port 25 network data aggregated from traffic monitors positioned in top enterprises throughout the US.
