  • The statistics are based on the known incidents listed here.
  • Since only some of the cases become known, the evaluations are not representative.
  • Industries where incidents are immediately visible due to public access (e.g. healthcare) are more represented than others.
  • An incident may be assigned to multiple countries or industries. Also, a country cannot always be assigned. So the totals shown on the charts may be different.
