The challenge of secure messaging
Certain communications or files are so sensitive that delivering them via email using the open, public internet is unacceptable. Since email is the most used business application, employees generally want to use it to easily deliver and receive all their communications and files, whether sensitive or not. They don't want to learn another application and be forced to switch between systems to conduct business. Furthermore, employers don't want more complexity and cost associated with more third-party services.
What organizations need is a user-friendly secure messaging service built directly into their email system that provides security and control over-and-above that which is provided using traditional email encryption, such as TLS.
