Connecticut data breach notification law: without unreasonable delay.
Connecticut's breach-notification obligations are set by Conn. Gen. Stat. 36a-701b. This page summarises the deadline to notify affected residents, the attorney general notification threshold, whether a private right of action exists, and the penalties for late or missing notification. Every provision is cited to its source statute and was verified in June 2026.

Statute

Conn. Gen. Stat. 36a-701b
Section CT.1
What the statute requires
Under Conn. Gen. Stat. 36a-701b, a business that owns or licenses computerized personal information of Connecticut residents must notify affected individuals without unreasonable delay, no later than 60 days after discovery.
Attorney general or state-agency notification is all breaches (no minimum resident threshold). Where required, the timeline is: no later than the time notice is provided to affected residents.
Section CT.2
What triggers notification
Like most US state statutes, notification is triggered by the unauthorized acquisition of unencrypted, unredacted computerized personal information that compromises its security, confidentiality, or integrity. Two concepts recur across the states and apply here.
Encryption safe harbor
Personal information that was encrypted, and where the encryption key was not also acquired, generally does not trigger notification. A stolen device with full-disk encryption is typically a non-event; an unencrypted record, or an encrypted record where the key was exposed alongside it, is a reportable breach.
Who must be notified
- [1] Affected Connecticut residents: 60 days
- [2] Attorney general / state agency: all breaches (no minimum resident threshold)
- [3] Consumer reporting agencies where the breach is large-scale
Section CT.3
Penalties and enforcement
Up to $5,000 per willful violation under CUTPA, plus injunctive relief and restitution.
Private right of action: No. Non-compliance is an unfair trade practice; only the AG enforces.

Section CT.4
How this compares to the strictest states
The strictest US deadlines are 30 days (California, Florida, Washington, Colorado, Maine, New York, New Jersey). The majority of states use a qualitative "without unreasonable delay" standard with no fixed day cap. Here is where Connecticut sits.
Connecticut imposes a fixed 60-day deadline. The strictest states cut this to 30 days, so Connecticut sits 30 days behind the tightest regimes.
