Privacy Data

Data Privacy: What 2019 Holds for U.S. Companies

The European Union’s General Data Protection Regulation (GDPR) went into effect in May 2018, clamping down on those that collect E.U. residents’ personal data—wherever they may be. There is much we could learn from the GDPR’s growing pains; but the GDPR is still in its infancy, and legislative wheels are already turning at home: U.S. lawmakers have begun flirting with GDPR-inspired omnibus data-privacy regimes. As a result, companies do not have the luxury of adopting a wait-and-see approach to data privacy compliance. The time to get up to speed is now.
