Founded in 2012, DPI focuses on trainings on the crossroads of data protection, governance and security. We believe in a digital and data driven world, where industries must build their innovation pipelines with security and privacy in mind. All stakeholders involved, from board members to data protection officers, information security professionals and data managers must understand how these domains interact and can be harmonized.
