What Cyber Insurance Requirements Apply in Michigan?

Michigan requires notice without unreasonable delay when an unauthorized person accesses and acquires qualifying personal information, unless a prudent assessment finds no likely substantial loss, injury, or identity theft. Michigan currently does not require a general Attorney General breach report, so build the resident and consumer-reporting-agency steps around the actual statute rather than assuming a state filing.

What Is Cyber Insurance?

Cyber insurance can help pay covered response costs and claims against your business after a cyber incident. If your business relies on data, software or outside providers, compare response limits, vendor outages and approval rules. Read the national Cyber liability guide.

What Should You Watch for With Cyber Insurance in Michigan?

Michigan Uses a Substantial-Harm Test
The owner or licensee need not notify if it determines the incident is not likely to cause substantial loss or injury, or identity theft, to a Michigan resident; the decision must reflect the care an ordinarily prudent person would use in similar circumstances. Ask who documents that decision and its evidence. ¹
Encrypted Data Is Covered if the Key Was Exposed
Michigan notice applies when unencrypted, unredacted personal information was accessed and acquired, or encrypted data was accessed and acquired by someone with unauthorized access to the key. Include key-management logs and recovery evidence in your incident service scope. ¹
Michigan Has No General AG Filing Duty
The Michigan Attorney General confirms current state law does not require companies to report breaches to that office; resident notice under MCL 445.72 still applies. Ask your broker whether the policy’s notice-response service distinguishes statutory filings from voluntary regulator reporting. ^1,²

Which Cyber Insurance Providers Have Michigan License Records?

These providers publish a national listing for Cyber liability; the license records below name the licensed entities and roles. Some records rely on company-reported information rather than independent regulator verification. A national listing does not confirm the product is available in Michigan. Check the regulator’s license lookup and confirm state availability for your business when requesting a quote.

Specialty Program Group LLC
TechInsurance’s current licensing page names Specialty Program Group LLC / SPG Insurance Solutions and lists state license numbers, but labels Rhode Island “Individual licenses” rather than identifying a license for the named agency. RI is omitted because this disclosure does not establish agency authority there; this is a search limitation, not an assertion that the company is unlicensed. The remaining state entries are company-reported and are not an insurance product availability map. ¹⁴

Its separate surplus-lines table includes Idaho number 870820, while a footnote says Georgia and Idaho do not issue agency-level surplus-lines licenses. Because those statements conflict for Idaho, this record keeps Idaho producer-only and does not treat the table number as established agency surplus-lines authority. The page is company-reported and does not establish product availability. ¹⁵
