The Global Privacy Enforcement Network’s annual survey focused on the management of data breaches by public and private entities; the 2019 sweep survey involved 16 Authorities for the processing of personal data, including the Italian one. The investigation has taken into account various aspects of the management of a data breach, including how the reports/notifications and the implementation of the counter-measurements to prevent the repetition of the breach were managed.  The Study revealed that only a few entities have an in-depth knowledge of data breach management.
