On July 22, 2022, companies are required to notify the Arizona Department of Homeland Security when they experience a data breach impacting more than 1,000 Arizona residents. This notification requirement is in addition to obligations to notify affected individuals, the Arizona state attorney general and the three largest national consumer reporting agencies. The notification to the Arizona Department of Homeland Security must be made within “45 days after a determination that there has been unauthorized acquisition and access that materially compromises the security or confidentiality of unencrypted and unredacted computerized personal information maintained as part of a database of personal information regarding multiple individuals.”
