The EU General Data Protection Regulation (GDPR) will start applying on 25 May 2018, affecting businesses operating within the EU or handling personal data of EU citizens. Businesses must ensure that all personal data is stored and processed in compliance with GDPR requirements. This includes storing data within the EU unless specific criteria are met, allowing individuals to request deletion of their data, implementing procedures for managing message history, ensuring proper agreements between data controllers and processors, maintaining high security standards, and having a plan in place for detecting and reporting data breaches. Businesses should conduct a data protection impact assessment (DPIA) and enable customers to withdraw consent for processing their personal data.
