I was wondering what most healthcare providers use for secure email between partners? Back when I was supporting Exchange 2003 we used to have secure site to site connections setup for email communication. Since Exchange 2010 they now have Mutual TLS, but I hear it can be difficult to setup. However our customer has a partner that wants us to setup Mutual TLS with them. Is it worth pursuing this, or is there a better way that would meet HIPAA compliance? <br />

When I was in financial we used ZixMail, but this customer says they want to avoid having anything setup on the end user computer. Last I remember, ZixMail requires an application to be installed and configured.

Encryption is the process of encoding messages or information in such a way that only authorized parties can read it. In an encryption scheme, the intended communication information or message, referred to as plaintext, is encrypted using an encryption algorithm, generating ciphertext that can only be read if decrypted. For technical reasons, an encryption scheme usually uses a pseudo-random encryption key generated by an algorithm. An authorized recipient can easily decrypt the message with the key provided by the originator to recipients, but not to unauthorized interceptors.
