How to cope with Spam of Web 2.0? Smarter spam solutions

Executive Summary
Spam is growing at record levels, and the objective of spam email has shifted to attempt to infect computers with malicious software. Furthermore, the high volume of spam not only impacts worker productivity, but is a significant burden on IT infrastructure. Reduction of spam to the lowest possible levels is therefore an important objective for any business.
This paper discusses best practices for defending your business against unwanted email using the unique Nitix AntiSpam technology. Nitix AntiSpam 2.0 integrates two different but complementary antispam engines – a network level antispam engine pre-screens emails at the SMTP layer. Email that passes through this pre-screening are further scanned using a content level antispam technology.
By combining two entirely different but complementary industry best-of-breed antispam solutions into a single easily deployed, zero configuration, ultra-low maintenance solution, Nitix AntiSpam 2.0 delivers the best possible solution to the SMB marketplace with performance, value, and effectiveness unrivaled by any other solution.

How Network Layer Spam Detection Works

The pre-emptive network layer engine allows Nitix AntiSpam 2.0 to provide an extremely efficient method of classifying spam based upon the sender’s source address, allowing a substantial portion of spam to be identified without having the email scanned by the more resource-intensive content based engine.

Nitix AntiSpam 2.0 may also be configured to promptly terminate the SMTP connection of identified offending email senders to provide even further processing savings as well as bandwidth savings from not having to deal with the data of the entire message.
The combination of these two separate engines provides overall spam effectiveness ranging from 98% to over 99% while simultaneously reducing the system load by over 75%.
