EU-US Privacy Shield is the trans-Atlantic data transfer agreement that might replace Safe Harbor. Safe Harbor was the agreement that allowed multinational organizations to store European citizens’ personal data in the US. The European Court of Justice struck down Safe Harbor in October. Privacy Shield puts in place more oversight for data protection for the U.S. and EU citizens. It also hardens rules as it relates to “onward transfer” of data to third-party data processors. The EU General Data Protection Regulation (GDPR) is expected to be ratified by European Parliament this spring.”]
