Google was hit with a $57 million fine over alleged General Data Protection Regulation violations this week—a hefty price most tech companies would like to avoid.

The financial penalty came from France’s data privacy enforcement agency, Commission nationale de l’informatique et des libertés (CNIL), on Monday. It’s the first GDPR fine to hit a major U.S. tech company. CNIL said in a press release that the penalty stemmed from a “lack of transparency, inadequate information and lack of valid consent regarding the ads personalization.”
