What the statute requires

New York's SHIELD Act requires businesses to notify affected residents of breaches of private information within 30 days of discovery, with notice to the Attorney General, Department of State, State Police, and Department of Financial Services regardless of size. Cyber liability insurance typically covers the forensics, notification, and legal review this statute drives, along with regulatory defense.

Consumer notification deadline
In the most expedient time possible and without unreasonable delay, but not later than 30 days after discovery of the breach
Regulator notice
Notify the New York Attorney General, the Department of State, the Division of State Police, and the Department of Financial Services of any breach regardless of the number of residents affected.
Credit bureau notice
Notify consumer reporting agencies when a breach requires notice to more than 5,000 residents.
Safe harbor
Notification is not required if the compromised data was encrypted and the encryption key was not acquired, or where the exposure is an inadvertent disclosure unlikely to cause harm.
Enforcement
Violations are enforceable by the Attorney General, who may seek civil penalties for each failure to notify subject to statutory caps.
