ABOUT CARTIER
Cartier is a French luxury goods brand founded in 1847 in Paris. Renowned for its high-end jewelry, watches, and accessories, Cartier is known for iconic collections like Love, Tank, Juste un Clou, and Panthère. A favorite among royalty and celebrities, the brand is a subsidiary of the Richemont Group, a Swiss luxury conglomerate. Cartier has a strong presence in the United States, with boutiques in major cities such as New York, Los Angeles, San Francisco, Miami, Las Vegas, Chicago, Houston, Boston, and Atlanta. Its U.S. headquarters is located in New York City, overseeing national operations. Cartier products are also sold through authorized retailers and department stores. With a large and growing American customer base, the U.S. remains a key market — making this data breach especially concerning for U.S. clients.
What Happened?
In June 2025, Cartier sent out notification letters to affected customers informing them of a cybersecurity incident. The company stated that hackers gained temporary unauthorized access to its systems and exfiltrated a limited amount of customer information.
“We are writing to inform you that an unauthorized party gained temporary access to our system and obtained limited client information,” the notification letter stated.
Although Cartier claims to have contained the issue and enhanced security measures, the data breach still poses a significant risk. The company has notified law enforcement and is working with a cybersecurity firm to investigate and remediate the incident.

Cartier has emphasized that no passwords, credit card numbers, or banking details were exposed in the breach.
However, the stolen information could still be used in phishing attacks or identity-related fraud. Cartier advises all affected customers to be on alert for suspicious communications.
“Given the nature of the data, we recommend that you remain alert for any unsolicited communications or any other suspicious correspondence,” the letter warned.
Notification letters outlining the scope of impacted information and providing protective measures were sent to affected individuals following the conclusion of the investigation.
