More and more large businesses are turning to a combination of message-security services and on-site security appliances to guard against malicious behavior carried out via e-mail and other messaging software,
a recent IDC study says.
An increasing number of the biggest corporations use security services to clean spam out of their e-mail traffic before the
messages ever reach corporate mail servers, according to an IDC report on messaging security.

These big businesses combine services with local security software and appliances that further lock down messages by employing
data-loss prevention, encryption and tight policies on data access and use, the study says.
IDC says that historically, small and midsize businesses flock to security services because they lack in-house expertise to
do the job themselves, but that is shifting.
The study says that 38% of businesses with more than 10,000 employees responded that they use messaging-security services.
That compares with 25% or fewer in three different size ranges of smaller businesses. The study surveyed 372 businesses
These services overall in combination with message-security appliances are making inroads against message-security software,
IDC says. In 2006, more than 60% of message-security money was spent on software with the rest split between services and
appliances. By 2011, that will shift so software and appliances are tied at about 35% each and services reaches about 29%.
The top five messaging security providers overall are Symantec, Trend Micro, McAfee, Message Labs and Microsoft. The study ranks the vendors in three subcategories, software, appliances and services.
Symantec is the only vendor that ranks among the top five in all three subcategories, the survey says.
Business concerns about messaging security include spam, protecting intellectual property and complying with regulations set
by government and industry groups. Automating security processes to keep up with regulators will be a major incentive for
businesses to invest more in messaging security, IDC says.
