AN ACT CONCERNING BREACHES OF SECURITY INVOLVING ELECTRONIC PERSONAL INFORMATION.
SB 117 requires companies holding Connecticut residents' electronic personal information to notify affected individuals within 60 days of discovering a security breach involving unencrypted data. It defines "personal information" broadly to include Social Security numbers, financial data, health records, and biometric details, and sets a "massive breach" threshold of 100,000 affected residents. Companies must also report breaches to the Attorney General and provide free identity theft prevention services (including credit freezes) for two years to affected residents. The law takes effect October 1, 2026, with limited exceptions for ongoing criminal investigations.

MINOR
The bill was renamed from 'Raised Bill' to 'Substitute Bill' to reflect its status as a revised version. The definition of a 'massive breach of security' was expanded to include breaches caused by unauthorized use of a computer network, not just unauthorized access. Additionally, the notice requirements now explicitly cover situations where data is 'reasonably believed' to be breached, ensuring residents are informed even before a breach is fully confirmed.
Scope change
The scope of the breach definition was broadened to cover unauthorized use of networks in addition to unauthorized access, and the applicability of notification requirements was clarified to include probable breaches.
DEFINITION
The definition of 'massive breach of security' was updated to include breaches occurring due to unauthorized use of a computer or computer network, expanding the triggers for what counts as a massive breach.
REQUIREMENT
The requirement to notify residents was updated to apply when data is 'reasonably believed' to have been breached, rather than only when it has definitely been breached.
TECHNICAL
The document title was changed from 'Raised Bill' to 'Substitute Bill' to indicate it is a revised version of the original legislation.
