(2) The computation of a licensee's deadlines shall begin on the day after the third-party service provider notifies the licensee of the cybersecurity event or the licensee otherwise has actual knowledge of the cybersecurity event, whichever is sooner. (3) Nothing in sections 375.1400 to 375.1427 shall prevent or abrogate an agreement between a licensee and another licensee, a third-party service provider, or any other party to fulfill any of the investigation requirements imposed under section 375.1407 or notice requirements imposed under this section. 5. (1) (a) In the event of a cybersecurity event involving nonpublic information that is used by the licensee that is acting as an assuming insurer or in the possession, custody, or control of a licensee that is acting as an assuming insurer and that does not have a direct contractual relationship with the affected consumers, the assuming insurer shall notify its affected ceding insurers and the commissioner or director of insurance for its state of domicile within three business days of making the determination that a cybersecurity event has occurred.

(c) Any licensee acting as assuming insurer shall have no other notice obligations relating to a cybersecurity event or other data breach under this section or any other law of the state.

(b) The ceding insurers that have a direct contractual relationship with affected consumers shall fulfill the consumer notification requirements imposed under section 407.1500 and any other notification requirements relating to a cybersecurity event imposed under this section. 6. In the case of a cybersecurity event involving nonpublic information that is in the possession, custody, or control of a licensee that is an insurer or its third-party service provider for which a consumer accessed the insurer's services through an independent insurance producer, and for which consumer notice is required by law, including section 407.1500, the insurer shall notify the producers of record of all affected consumers of the cybersecurity event no later than the time at which notice is provided to the affected consumers. The insurer is excused from this obligation for those instances in which it does not have the current producer of record information for any individual consumer. (L. 2025 H.B. 974, et al.)
