Safe Harbor is a framework that allows the transfer of personal data from the EU to the US in compliance with EU data privacy laws. It provides a bridge between differing US and EU privacy approaches through voluntary self-certification to its principles by organizations doing business between the regions. The principles address issues like notice, choice, security and enforcement to protect EU citizens' privacy rights when their data is transferred to the less restrictive US context. While initially controversial, Safe Harbor has helped enable transatlantic data flows for many companies over the past 15 years.
