The GDPR, EU regulation for data breaches and for the management and protection of sensitive and personal data and for the protection of privacy, requires companies to establish the register of data breaches to ensure proper data processing. The personal or sensitive data of a customer of a bank or the personal and sensitive data of a patient of a hospital or a private clinic or a large analysis laboratory may be violated by compromising the confidentiality, integrity or availability of the data stored by private companies or public entities.
