Using the industry standard S/MIME (Secure MIME) protocol, Secure Messenger removes both the confidentiality and integrity threats by ensuring that e-mail messages are read only by designated recipients, regardless of their e-mail platform. Secure Messenger's convenient and intuitive user interface allows S/MIME files to be dragged and dropped into any e-mail client on the desktop, giving users freedom of choice, while securing their electronic environment over the Internet or corporate Intranet. Secure Messenger also includes special security plug-ins for a variety of e-mail clients that integrate S/MIME security seamlessly with the messaging application. 
One of the largest barriers to everyday use of encryption and digital signatures is that current solutions are cumbersome and difficult to understand. With Secure Messenger, sending a signed or encrypted message is as easy as clicking a toolbar button or checking a check box. 
ecure Messenger uses the industry standard Secure MIME (S/MIME) protocol, providing interoperability with other S/MIME compliant products. In addition to supporting the range of encryption grades discussed above, Secure Messenger also supports a wide variety of encryption and digital signature algorithms to provide the broadest interoperability available.
