The notice must be made without unreasonable delay, consistent with the legitimate needs of law enforcement, as provided in subsection (3), or consistent with any measures necessary to determine the scope of the breach and restore the reasonable integrity of the data system.

(2) Any person to whom personal information is disclosed in order for the person to perform an insurance function pursuant to this part that maintains computerized data that includes personal information shall notify the licensee or insurance-support organization of any breach of the security of the system in which the data is maintained immediately following discovery of the breach of the security of the system if the personal information was or is reasonably believed to have been acquired by an unauthorized person.

(3) The notice required by this section may be delayed if a law enforcement agency determines that the notice will impede a criminal investigation and requests a delay of notice. The notice required by this section must be made after the law enforcement agency determines that the notice will not compromise the investigation.

(4) Licensees, insurance-support organizations, and persons to whom personal information is disclosed pursuant to this part shall develop and maintain an information security policy for the safeguarding of personal information and security breach notice procedures that provide expedient notice to individuals as provided in subsection (1).
