  The GDPR grants data subjects certain rights, like the right to access their
data from companies, but in practice multiple problems exist with exercising
these rights such as unknown data holders or interpreting the received data.
Small and medium enterprises on the other hand need to facilitate the
obligations given by the GDPR, but often lack proper systems, staff and other
resources to do so effectively. For the GDPR to be effective in practice, these
problems need to be addressed. With the work at hand we provide an overview of
existing software solutions for these problems (from an internet research),
discuss to which degree they solve the various problems and what issues remain.
