The Total Cost of Ownership For Mail Server Security

"Today, anywhere from 87% to 95% of all email is spam and approximately one out of every 160 emails contains a virus. That means that an organization with an average email volume of 100,000 messages per day, can expect to receive up to 95,000 spam messages and 625 virus-laden messages every day. As a result, robust anti-spam, antivirus and other malware defenses are absolutely critical to the health of any organization’s email infrastructure. These defenses must be continually updated, they must be easy to use and – given that they are a necessary component of any organization’s defense system – they should cost as little as possible to deploy and manage.
This report discusses a research program comparing four leading mail server security solutions designed for Microsoft Exchange environments. The four solutions – from Trend Micro, Symantec, Microsoft and McAfee – were cited as among the most commonly considered solutions in a separate research project undertaken by Osterman Research earlier in 2007."
