The functionality that is most valuable is the solution's ability to detect patient data in email attachments. Whenever a user sends out an email with patient data embedded in an attachment, it triggers an alert. The tool can detect a social security number and various other forms of patient identity. Emails are then automatically generated and sent.

Improvements can be made to the products generic offering. It's not customized for health care. It doesn't understand the meaning of health care related concepts. Providing a greater degree of industry specificity would make the tool much more unique and valuable.
