Hawaii Cybersecurity Laws You Should Know (2026)

Mitch Wolverton

Hawaii doesn’t currently have a broad consumer privacy law like California or Colorado, but it does have established data breach notification requirements that apply to businesses and government agencies handling personal information. Staying compliant with Hawaii cybersecurity laws is critical for protecting residents’ data, avoiding penalties, and building consumer trust. Below, we break down the key state and federal laws that apply to Hawaii businesses in 2026 and beyond.

Hawaii Cybersecurity Laws

Hawaii Data Breach Notification Law (HRS Chapter 487N)

The core cybersecurity statute in Hawaii is the data breach notification law found at Hawaii Revised Statutes Chapter 487N. Under this law:

  • Businesses and government agencies that own or license personal information of Hawaii residents must notify affected individuals without unreasonable delay after discovering a security breach.
  • Notice must account for legitimate law enforcement needs and the time needed to investigate the breach and restore system security.
  • If more than 1,000 residents are affected, the entity must also notify the Hawaii Office of Consumer Protection (OCP) and nationwide consumer reporting agencies without unreasonable delay.

Personal information covered includes an individual’s first name (or initial and last name) in combination with:

  • Social Security number;
  • Driver’s license or state ID number; or
  • Account numbers, credit or debit card numbers, access codes, or passwords that allow access to financial accounts.

Notice must be clear and conspicuous and may be delivered via written mail, email (if consented), telephonic notice, or other approved methods.

Encryption Safe Harbor: If the personal data breached was encrypted or redacted and the encryption key was not compromised, notification may not be required under certain conditions.

Hawaii Consumer Protection Law & Deceptive Practices

While Hawaii does not yet have a comprehensive consumer privacy act, its unfair or deceptive practices statute generally prohibits misleading or deceptive acts in trade and commerce, including false claims about data security or privacy safeguards.

Proposed Privacy Framework Updates (SB1038 and Related Bills)

In 2025, Hawaii considered updates to Chapter 487N to expand the definition of “personal information” to include additional identifiers such as usernames, phone numbers, and other covered data elements, reflecting trends in more robust state privacy laws. These proposals may influence future requirements in 2026 and beyond.

Payment Card Industry Data Security Standard (PCI DSS)

PCI DSS applies to Hawaii businesses that process credit card payments. It requires encryption, access control, and continuous monitoring to prevent payment data breaches.

Health Insurance Portability and Accountability Act (HIPAA)

HIPAA applies to Hawaii healthcare organizations and business associates that handle personal health information (PHI). It mandates administrative, technical, and physical safeguards for patient data.

Gramm-Leach-Bliley Act (GLBA)

Financial institutions in Hawaii must comply with GLBA, which requires secure information systems, employee training, and consumer privacy notices.

General Data Protection Regulation (GDPR)

GDPR applies to Hawaii businesses that collect or process personal data from EU residents. It mandates explicit consent, transparency, and the right to delete personal information.

Cybersecurity Requirements for Financial Services Companies (NYDFS 23 NYCRR 500)

Financial institutions in Hawaii with operations in New York must comply with NYDFS cybersecurity regulations, requiring encryption, multifactor authentication, and incident reporting.

NIST Cybersecurity Framework

The NIST Cybersecurity Framework is widely used across Hawaii’s key industries, particularly technology, energy, and manufacturing, to identify, protect, detect, respond to, and recover from cybersecurity incidents.

Federal Trade Commission (FTC) Act

Under the FTC Act, Hawaii businesses must maintain reasonable cybersecurity standards and cannot misrepresent their data protection practices.

Children’s Online Privacy Protection Act (COPPA)

If your Hawaii business collects personal data from children under 13, COPPA applies. It requires verified parental consent and limits data sharing or tracking.

Sarbanes-Oxley Act (SOX)

Publicly traded companies in Hawaii must comply with SOX, which enforces accurate financial reporting and secure data management systems.

Family Educational Rights and Privacy Act (FERPA)

FERPA applies to Hawaii schools and businesses handling student educational records. It requires written consent before disclosing identifiable student data.

Cyber Incident Reporting for Critical Infrastructure Act (CIRCIA)

CIRCIA requires critical infrastructure entities, including those in energy, technology, and manufacturing, to report major cyber incidents to the Cybersecurity and Infrastructure Security Agency (CISA) within 72 hours.

CAN-SPAM Act

The CAN-SPAM Act governs commercial email marketing practices, requiring accurate sender information, clear subject lines, and simple opt-out mechanisms.

Defense Federal Acquisition Regulation Supplement (DFARS)

Hawaii defense contractors must comply with DFARS cybersecurity standards aligned with NIST SP 800-171, ensuring protection of controlled unclassified information.

Section 5 of the FTC Act (Unfair or Deceptive Practices)

Section 5 prohibits deceptive or negligent cybersecurity practices, holding Hawaii businesses accountable for failing to protect consumer data or misrepresenting security controls.

Best Practices for Hawaii Businesses

Since Hawaii’s breach notification law focuses heavily on timely and complete notice, organizations operating in the state should adopt the following cybersecurity best practices:

  • Conduct regular risk assessments and penetration tests.
  • Implement robust encryption and access controls for sensitive data.
  • Develop incident response and breach notification plans consistent with Hawaii’s legal timelines.
  • Train employees to recognize phishing and other common cyber threats.
  • Document breach investigations and risk assessments to support compliance.

Following widely recognized frameworks like NIST, CIS Controls, and ISO 27001 can demonstrate due diligence and strengthen cybersecurity posture.

Conclusion

Hawaii’s cybersecurity landscape centers on data breach notification requirements under Chapter 487N, which mandate prompt notice to affected individuals and regulators after unauthorized access to personal information. While the state currently lacks a comprehensive privacy law like the CCPA/CPRA, legislative proposals suggest an ongoing interest in broader data protection standards.

By complying with Hawaii breach laws and federal cybersecurity standards, businesses can protect customer data, avoid penalties, and reduce reputational risk.
