Multi Level File Protection

  • Need2Know operates with a single source of truth
  • Data handlers can mark multiple sections of information within an original document with differing levels of audience / redaction mark-up.
  • A publication is then generated for each audience.
  • Security is enhanced because if a document is not being read or edited, then it doesn’t exist. Documents are brought together when needed and broken into encrypted pieces when stored on a secure server by our Need2Know server application.
