How Will New York’s New Data Breach Law Impact Businesses?

Feb 12, 2025

The recent amendment to New York General Business Law § 899-aa, signed into law by Governor Kathy Hochul on December 24, 2024, introduces significant changes to the state’s data breach notification requirements. This legislation mandates that businesses now inform affected New York residents of data breaches within thirty days of discovery, replacing the previous guideline that required notification “in the most expedient time possible and without unreasonable delay.” This new, specific timeline aims to ensure timely communication while reducing ambiguity regarding notification periods, marking a substantial shift in how businesses must handle data breaches.

This amendment also includes a requirement that the New York Department of Financial Services (NYDFS) be notified of breaches impacting New York residents’ personal information. Adding NYDFS to the roster of state regulators obligated to be informed in such instances ensures that New York’s standards are aligned with states like Colorado, Florida, Maine, and Washington, which also enforce a thirty-day notification period. Moreover, businesses that maintain, but do not own, personal information have also had their responsibilities clarified. Initially expected to notify data owners immediately, these businesses must now inform them within thirty days of discovering a breach.

Mandated Timeliness and Enforcement

These revisions are significant as they establish a stricter timeline within which businesses must act, aiming to enhance consumer protection and align more closely with national standards. By enforcing a thirty-day limit for breach notifications, New York seeks to ensure that consumers are promptly informed about any potential risks to their personal information. The law further promotes accountability and swift action in safeguarding consumer data, reinforcing the necessity of transparent and timely communication when breaches occur.

Additionally, the allowance for delayed notification due to legitimate law enforcement needs remains intact. However, the revised law eliminates language previously permitting businesses to delay notifications for measures needed to determine a breach’s scope and restore system integrity. This change emphasizes the importance of rapid disclosure to affected parties, reducing the window businesses had to manage the aftermath of a breach before informing consumers. By narrowing the scope for delay, the state underscores the priority of consumer rights and immediate transparency in the event of a data breach.

Broader Implications and Responsibilities

Beyond the immediate impact on notification timelines, the amendment also integrates broader responsibilities for various stakeholders involved in data security. Businesses that handle personal information but do not own it must now navigate clearer expectations regarding their role in breach disclosure. Previous legislation required them to notify data owners or licensees “immediately,” a term open to interpretation. The new amendment provides a definitive thirty-day period, reducing potential confusion and ensuring a more uniform response protocol in instances of data breaches, promoting consistency across different entities and sectors.

The updated law also builds on the foundation laid by the 2019 Stop Hacks and Improve Electronic Data Security (SHIELD) Act, which expanded definitions of personal information and data breaches, extending security obligations to more entities handling New York residents’ data. By continuously evolving its regulatory landscape, New York demonstrates commitment to protecting consumers’ personal information and compelling businesses to adopt proactive data security measures. This progression not only enhances local standards but also aligns with broader trends in national cybersecurity legislation, setting precedents for other states to consider.

Future Considerations and Business Adaptation

Governor Kathy Hochul signed an amendment to New York General Business Law § 899-aa on December 24, 2024, bringing notable changes to data breach notification requirements. The updated law obligates businesses to notify impacted New York residents within thirty days of discovering a data breach. This strict deadline replaces the previous guideline that required notification “in the most expedient time possible and without unreasonable delay.” The new timeline aims to foster prompt communication and reduce ambiguity for businesses managing data breaches.

Additionally, the amendment stipulates that businesses must inform the New York Department of Financial Services (NYDFS) about breaches affecting New York residents’ personal information. This aligns New York’s standards with other states like Colorado, Florida, Maine, and Washington, which also enforce a thirty-day notification rule. Moreover, businesses that maintain but do not own personal information have clarified responsibilities. They are now required to notify data owners within thirty days of a breach, instead of immediately, ensuring all stakeholders are promptly informed.
