Connecticut Data Breach Notification Law
C.G.S. § 36a-701b; Connecticut Data Privacy Act
Connecticut's data breach notification law (C.G.S. § 36a-701b) requires notification within 60 days of discovery. Connecticut is notable for requiring that the AG be notified simultaneously with the affected individuals — not after a threshold is met. The state also passed the Connecticut Data Privacy Act (CTDPA) in 2022, which took effect in 2023 and provides Connecticut consumers broad data privacy rights including the right to access, correct, delete, and opt out of targeted advertising.
What This Law Covers
Connecticut's breach notification law requires businesses and government agencies that maintain personal information about Connecticut residents to notify affected individuals when that information is subject to unauthorized access or acquisition. "Personal information" typically includes Social Security numbers, driver's license numbers, financial account numbers, and in many states has been expanded to cover medical data, biometric data, online credentials, and tax IDs.
What the Company Must Tell You
A compliant breach notification to Connecticut residents must include:
- ✓A description of the breach — what happened and when
- ✓The types of personal information that were involved
- ✓What the company is doing to investigate and contain the breach
- ✓Steps you can take to protect yourself (e.g., credit freeze, fraud alert)
- ✓Contact information so you can ask questions
