What Did Marriott Do to Address the Issue?

Immediate Response

Marriott’s first priority was to contain the breach and prevent any further unauthorized access to their systems. They quickly engaged cybersecurity experts to investigate the attack and identify the scope of the damage. They also notified law enforcement agencies and regulatory bodies, including the FBI and the Information Commissioner’s Office (ICO) in the UK.

To reassure their customers, Marriott set up a dedicated website and call center to provide information and assistance to those affected by the breach. They also offered free enrollment in a personal information monitoring service for one year.

Long-Term Solutions

Marriott recognized that they needed to take more proactive steps to prevent future cyber attacks and protect their customers’ data. They invested in upgrading their cybersecurity systems and procedures, including implementing multi-factor authentication for access to their systems and encrypting sensitive data.

They also conducted a review of their IT systems and processes to identify any potential vulnerabilities and improve their overall security posture. This included hiring additional staff and partnering with outside experts to provide ongoing cybersecurity support and guidance.

Legal Action

Marriott faced legal action from customers and regulators in several countries as a result of the data breach. In July 2019, the ICO announced that they intended to fine Marriott £99 million for violations of the General Data Protection Regulation (GDPR).
