If you received a data breach notification from CyrusOne, your first step should be to carefully review the letter for any specific guidance or services offered, such as credit monitoring.

Under Indiana's data breach notification law (Indiana Code § 24-4.9-3-1 to -3), companies are legally required to protect your personal information and to inform you if that data is compromised. This law underscores a company's duty to safeguard the sensitive information they collect and store. When a breach occurs, it suggests a potential failure in these security duties.
Victims of a data breach may have grounds to seek compensation for damages, which can include financial losses, identity theft resolution costs, and even emotional distress. Companies like CyrusOne have a legal obligation to implement reasonable security measures to prevent such incidents. If these measures were insufficient, individuals affected by the breach may be able to pursue a claim.
Understanding your legal rights after a data breach is critical. You are not without recourse. Consulting with an attorney can help you determine the best course of action. Many firms offer a free case review to help you explore your options without any upfront cost or obligation.
