What Triggers Ohio Data Breach Notification
Ohio's notification requirement is triggered when a business discovers or reasonably believes it has discovered a breach of security affecting the personal information of Ohio residents.
Personal information under Ohio law includes: first name (or initial) and last name in combination with any of the following — Social Security number, driver's license or state ID number, account numbers (financial, credit, or debit) with access codes, medical or health insurance information, or username and password.
Breach of security means unauthorized access to and acquisition of computerized data that compromises the security or confidentiality of personal information and causes or is reasonably believed to cause a material risk of identity theft or fraud.
Importantly, Ohio law includes an exception: notification is not required if the personal information was encrypted, redacted, or otherwise rendered unreadable — as long as the encryption key was not also compromised. This is a significant incentive for businesses to encrypt personal data at rest and in transit.
The 45-Day Notification Requirement
Ohio requires notification to affected individuals "in the most expedient time possible, but not later than 45 days following the discovery of the breach." This is shorter than many other states (Florida requires 30 days; Texas requires 60 days) and significantly shorter than GDPR's 72-hour requirement for EU-regulated organizations.
Who must be notified: All Ohio residents whose personal information was, or is reasonably believed to have been, accessed and acquired by an unauthorized person. If more than 1,000 residents are affected, consumer reporting agencies must also be notified.
Notification method: Written, electronic (if the individual has consented), or substitute notice (for breaches affecting 500,000+ residents or when costs would exceed $250,000). Substitute notice includes email, website posting, and notification to major statewide media.
Required content: A description of the breach, the types of information involved, the steps taken to investigate and address the breach, steps affected individuals can take to protect themselves, and contact information for the business.
Ohio Safe Harbor — Your Defense Against Breach Liability
The Ohio Data Protection Act (ORC Chapter 1354) creates an affirmative defense — the Safe Harbor — for businesses that are sued in Ohio courts following a data breach. To qualify, a business must demonstrate that at the time of the breach, it:
(1) Created, maintained, and reasonably complied with a written cybersecurity program;
(2) That program contained administrative, technical, and physical safeguards for the protection of personal information; and
(3) The program reasonably conformed to one of the recognized frameworks, which include: NIST CSF, NIST SP 800-53, CIS Controls, ISO 27001/27002, SOC 2 criteria, HIPAA Security Rule, or GLBA Safeguards Rule.
The Safe Harbor is an affirmative defense, not immunity. You must affirmatively raise and prove it in court. This means two things: (1) you must actually have implemented the framework controls, and (2) you must have documented that you did so. A program that was real but undocumented cannot be proven.
