Using ConfidentSend™ to Remove Hidden Data & Metadata

When an email is being sent, ConfidentSend™ prompts the user for hidden data types to be removed from the attachments. ConfidentSend™ then inspects the attachments and removes these hidden data types, while keeping the rest of the data intact, and sends the email to the recipients. ConfidentSend™ can also be configured to clean attachments automatically without prompting for purification options.
