Why Secure Email?
The benefits of email communication are numerous and widely recognized, but because of its vast size and reach, many people have a false security with respect to email.
Secured email can provide not only privacy protection, but also productivity enhancement by enabling organizations to move more sensitive and higher value transactions online, as well as enabling electronic delivery of regular communications with customers and partners (such as billing and account statements, insurance claims and application processing documents).
Messages, previously limited to more traditional methods of communication such as faxes or postal mail to security concens, now be rity online.
And with the recent expansion of government and industry regulations such as Sarbanes-Oxley and PCI (Payment Card Industry) the need to secure email communications has become an important element of corporate compliance. The ability to secure mail concerns, communications will not only protect and build a company’s brand equity, but can also help to strengthen relationship wits its suppliers, partners and customers.

Internal Communication Between Employees (Enterprise)
Email generated by day-to-day communications between employees with an enterprise constitutes the vast majority of communications. These internal messaging environments tend to be relatively homogeneous and are usually based on a single email infrastructure, such as Microsoft Exchange or Lotus Notes, although many companies must manage multiple messaging platform as a result of consolidations, mergers, acquisition or local/regional IT deployments.
The requirement for security is often departmentalized in areas such as Legal, R&D, HR and Finance, or at the CEO and director board level where confidential information is frequently exchanged.

Some of the key characteristics of an enterprise messaging environment are as follows:

• Email is a priority tool for collaboration
• The majority of emails are exchanged within the enterprise
• Email reach is expanding to the mobile workforce through the use of email-enabled wireless devices
• Instant Messenger applications such as MSM IM, if enabled within an organization, are widely used by employees to discuss both work, and non-work related topics, and even to exchange file attachments

Communication With Partners (B-to-B)
Inter-organizational email is growing rapidly as organizations exploit the business advantages of fostering closer relationship with their customers, partners and suppliers.
In this type of exchange , we are more likely to encounter a heterogeneous environment where organizations are communicating between two interoperable, yet different email infrastructures.

Typically these environments can be characterized by the following points:
• Information exchanges are between individuals collaborating to accomplish a specific goal, and flow both ways
• The partner has an existing email environment that they are not prepared to change
• Web mail access to the email environment may be an option used by the partner company
• Both parties have a vested interested in securing their information exchange
• Security is dictated by standards-based protocols that are mutually supported by each organization’s email infrastructure (primarily S/MIME)

Examples of this type of information exchange are wide-ranging, covering service contracts, financial auditing, legal and management consulting to more cooperative ventures like joint design and development, organizational mergers or inter-governmental collaboration.
