Protecting Confidentiality with the Secure Email Add-In

If you work with personal information, such as health, financial or other confidential information, you can protect its confidentiality and privacy by using MessageLabs Policy Based Encryption. The Secure Email Add-In was developed by Zix Corporation to be used with the MessageLabs Policy Based Encryption service. The Secure Email Add-In adds an Encrypt & Send button to your Microsoft Outlook or Lotus Notes email client that, when clicked, forces an email message to be sent encrypted.

By installing the Secure Email Add-In and setting up a content control rule, you can force confidential information to be sent securely. For additional information on how to setup a content control rule, see Setting Up a Secure Email Content Control Rule.
