Representatives from some of the world’s most powerful tech companies, Facebook Inc., Uber Technologies Inc., Dropbox Inc. and, spoke on a panel this week that addressed the challenges potentially posed by General Data Protection Regulation compliance.

The discussion, hosted by the High Tech Law Journal at Santa Clara University School of Law on Wednesday night, brought leaders from all four companies together to discuss how they’re preparing for the impending GDPR implementation date. On May 25, the new regulation on data protection and privacy will kick in for all companies collecting and processing European Union citizens’ data.
