Can I use Pipefile to send sensitive documents to clients?

Pipefile is designed for the workflow of collecting documents. Documents can be sent via our attachments feature however this is designed for sharing sample documents and blank forms. If you plan on attaching sensitive information, we recommend using password protected PDFs as attachments are not afforded the same level of security as uploaded documents. Attachments are not encrypted with GPG and are not password protected. They are transferred via TLS and are addressed using highly unguessable URLs via UUID v4.
