IronPort stops 98% of image spam

By | November 14, 2006

IronPort has announced significant progress in the war against image spam. The company is reporting that its product, IronPort Anti-SpamTM, stops 98 percent of image spam – twice the accuracy of any other enterprise class spam product.

The company adds that their Context Adaptive Scanning Engine (CASE), which examines the complete context of a message and is very effective in stopping image spam, has driven a significant number of new customers to IronPort.

Current statistics from IronPort’s Threat Operation Center confirm the worldwide increase in image spam. Among the findings:

  • Worldwide spam volumes increased from 31 billion messages a day in October 2005 to 61 billion messages per day in October 2006, an increase of nearly 100%.
  • Image spam reached a new high of 25% of total spam volume in October 2006 compared to 4.8% in October 2005, an increase of 421%.
  • Due to the increase in image spam, the average spam message size has grown from 8.9KB to 13KB, a 46% increase.
  • Bandwidth used by spam increased from 275 terabytes per day in October 2005 to 819 terabytes per day in October 2006, an increase of nearly 200%.

“Due to increases in spam and declining capture rates, the average email user is seeing two to three times more spam since the start of 2006,” said Tom Gillis, Senior Vice President of Worldwide Marketing at IronPort. “Catch rates are falling because signature-based solutions can’t keep up with spammer’s rapidly changing randomization techniques. IronPort’s success is based on a solid foundation of technology prowess and our ability to quickly marshal resources to stop the latest Internet threats.”
