Also, the European Union will soon roll out its equivalent to Sarbanes-Oxley, and so compliance is quickly becoming a must-have
feature for security appliances, he says.
McAfee has also enhanced its appliances’ spam-catching abilities by adding an IP address reputation service provided by e-mail
security hosted service provider Postini. Powered by Postini’s Threat Identification Network, the appliances’ anti-spam module
can now flag inbound e-mail coming from an IP address with a questionable reputation and immediately reject the message, significantly
reducing the amount of spam entering a company’s network while improving the appliance’s performance by cutting down on the
number of messages to be scanned, they say.
Pricing for McAfee’s E-mail Compliance module starts at $16.03 per user. It works with McAfee’s Secure Messaging Gateway and
Secure Internet Gateway appliances.
CipherTrust has also upgraded its IronMail messaging security appliances with new compliance features. The company on Monday
introduced its Compliance Profiler analysis engine that it says goes beyond word matching to learn about the content being
sent out of an organization so it can flag compliance breaches. The new analysis engine uses artificial intelligence to help
prevent employees from disseminating sensitive information, according to Atri Chatterjee, senior vice president of marketing
with CipherTrust.
Compliance Profiler matches outbound e-mail messages with existing corporate documents to learn which should not be sent outside
the organization. It does this in three ways: through adaptive lexical analysis that learns the type of content considered
confidential by an organization; through clustering, or correlating relationships among words in a document and the frequency
with which they occur; and fingerprinting, which breaks a document down into components and assigns unique alphanumeric identifiers
to each portion so they can be easily identified, Chatterjee says.
