As email has become the preferred medium for business communications, organizations have become increasingly concerned about ensuring the security of individual messages. Email is now used to transmit both unclassified and sensitive or confidential information across all parts of the enterprise, including operational data, trade secrets, legal documents, financial information and human resources data.
The need to secure confidential information and comply with a growing body of regulations that govern the transmission of private data have made policy-based email encryption a “must have” feature of a complete messaging security solution.
Email-borne viruses, worms and trojans continue to pose a substantial threat to enterprise operations. A competent messaging security solution should provide an always-up-to-date anti-virus solution with convenient, centralised administration, high-performance message analysis and flexible anti-virus policy management.
Unsolicited Commercial E-mail, or Spam, has become a widespread problem because it is financially profitable. This is due to the low start-up costs for spammers, and because of the extremely low cost of sending each new spam message.
Spam is not only growing in volume, but also changing in nature; in order to be effective, a spam filtering solution must be self-updating and rely on several different technologies.
