The Secure E-Mail provides PKI security solutions for leading e-mail applications which include Microsoft Outlook, MS Outlook Express, Netscape Messenger and Lotus Notes. All solutions support the S/MIME standard to provide interoperability between secure messaging clients.

Using public key cryptography, confidential information in the forms of EDI docuements, images, graphics and drawings can be sent by Secure E-Mail as attachments and be transmitted via the Internet securely. With digital signature, the Secure E-mail message provides the non-repudiation of origin. And the digital signature applied is also used for acknowledgements, which provides the non-repudiation of receipt.

The Secure E-Mail has been integrated with the Secure EDI's traditional EDI system, which enables the receving/sending of EDI information in the form of e-mail contents or attachments.
