With the introduction of healthcare orientated dictionaries and entities (available from 19th September 2017) you can easily search for one or more sensitive information type. Not only does this require fewer steps, it provides greater control. A default healthcare policy is provided with this functionality.

 

This guide explains how to:

  • Add the healthcare dictionary to a Content Examination definition.
  • Configure the default healthcare policy including:
    • Excluding entities from content matches.
    • Adding additional entities.
