E-mail is the most widely recognized vehicle for distributing critical business data. In recent years, regulatory compliance laws have emerged, driven by the need to protect confidential and highly sensitive information. This recognizes that everyday communication between the workforce and the outside world has now become a business risk. As a result, organizations have been mandated to monitor the content of outbound information. Compliance requirements, whether regulatory or self-imposed for corporate governance, now touch every organization, no matter their size or market focus.
