PALO ALTO, CA -- (MARKET WIRE) -- April 11, 2007 -- The Radicati Group, Inc.'s latest study, "Email Security Market, 2007-2011," offers an in-depth analysis of the market for Email Security. The study divides the market into three distinct segments: email security software, email security appliances, and hosted email security services. It provides market size, installed base and revenue market share by vendor, four-year forecasts, and much more.

The report explains that stopping spam remains a top messaging priority for most organizations, and the past year's image spam and botnet attacks have overwhelmed many corporate email networks.

According to the study, many software-based security solutions are increasingly being displaced by appliance-based solutions and hosted email security services, due to their ease of deployment and simplicity. These two segments are forecasted to experience strong growth throughout the next four years.

In the report, The Radicati Group forecasts that the overall email security market is expected to grow from $3.3 billion in 2007, to over $5 billion in 2011.
