Only 40 percent of companies have deployed systems aimed at filtering email for pornography.
White Paper: Controlling Unwanted Content
Perhaps the most effective way to filter email for unwanted content is to scan messages for keywords. These can be anything from offensive, profane, and pornographic terms, to words or phrases that represent company-sensitive information, like “Project XYZ,” or “Company ABC Projected Earnings.” Usually content filtering technologies come pre-configured with lists of standard keywords – offensive material, pornography, and profanity. More sophisticated solutions allow an enterprise to add its own keywords, so email flowing into and out of its network can be scanned for company-specific content.
Attachment control is necessary to both prevent unwanted and illegal content and to reduce bandwidth congestion. A good content control solution allows an enterprise to select the types and size of attachments to block. According to Osterman Research, 75 percent of enterprises block one or more types of email attachments, and 51 percent of enterprises block email messages that exceed a certain size. At a minimum, good email filters should have the capacity to block attachments containing certain unwanted file types, and messages or attachments that exceed a given size.
MANAGED CONTENT CONTROL SOLUTIONS
An enterprise must utilize all of the above techniques for the best protection against unwanted content. However, gathering and implementing these solutions separately can be expensive and time-consuming. Increasingly, enterprises are looking for solutions that provide many content control techniques in one bundled service. But most bundled services still require in-house installation, integration and maintenance, necessitating increased hardware, software, and IT resources.
For this reason, managed content control solutions are being utilized by organizations intent on adding protection without dealing with the hassle and expense of providing that protection in-house. MX Logic’s Content and Attachment Filtering, part of its comprehensive email defense solution, is ideal for enterprises of any size.
