In May 2014, Rowan Companies experienced a system intrusion that compromised personal information of employees, vendors, and contractors. The breach led to subsequent misuse of credit cards, PayPal accounts, and bank details belonging to affected individuals. Investigators suspected the unauthorized network access originated from compromised login credentials. In response, the organization engaged forensic specialists, mandated a company‑wide password reset, and restricted external network access points. Rowan Companies deployed enhanced monitoring controls and initiated further security upgrades to strengthen its defenses. Affected individuals were offered complimentary credit monitoring services as part of the remediation effort.

The source material does not specify any parent or subsidiary relationships for Rowan Companies, indicating it operated as an independent entity at the time of the reported incident. No additional ownership details are provided in the available information. Subsequently, Rowan Companies combined with Ensco plc to form Valaris Limited, altering its corporate structure. This concludes the factual profile based on the confirmed information supplied.
