Missouri Adopts New Data Breach Notice Law – DataBreaches.Net

Missouri Governor has signed House Bill 974, “The Insurance Data Security Act,” establishing comprehensive data security standards, breach investigation requirements, and notification protocols for insurers and licensed entities effective January 1, 2026. Legal experts J. Randall Coffey, Daniel Pepper, and Jillian Seifrit from Fisher Phillips outline ten critical provisions that insurance companies and licensed entities must understand to ensure compliance with the new legislation, which represents Missouri’s entry into the growing national trend of state-specific insurance data protection laws. The Act will require insurers to implement robust cybersecurity frameworks, establish formal breach response procedures, and adhere to specific notification timelines when security incidents occur, aligning Missouri with other states that have enacted similar insurance-focused data security regulations. This legislation reflects the insurance industry’s increasing regulatory focus on cybersecurity given the sector’s handling of vast amounts of sensitive personal and financial information, while the authors’ analysis at JDSupra provides detailed guidance on how Missouri’s approach compares to existing state laws and what preparatory steps organizations should take before the January 2026 implementation date. Insurance companies operating in Missouri should begin reviewing their current data security practices, breach response plans, and notification procedures to ensure full compliance with the new requirements.​​​​​​​​​​​​​​​​
