Mississippi data breach notification law

What this means if you sell security services

Mississippi sets no fixed deadline, only "without unreasonable delay," so filings can land weeks after discovery, often after the organization has finished its first response and started asking what to do differently. There is no Attorney General notice requirement, so Mississippi incidents surface mainly through SEC and HHS filings and through other states' records, channels fewer competitors watch. The law itself gives individuals no right to sue, so the conversation centers on regulator penalties and remediation rather than lawsuits.

Requirements in detail

Statute
Miss. Code Ann. § 75-24-29
Deadline to notify residents
Without unreasonable delay, subject to law enforcement delay and the time needed to investigate, identify affected people, and restore the system. Notice is not required if, after an appropriate investigation, the business reasonably determines that the breach will not likely result in harm.
Attorney General notification
No. Mississippi's law does not require notice to the Attorney General or to consumer reporting agencies.
Penalties
Failure to comply is an unfair trade practice enforced by the Attorney General under the Mississippi Consumer Protection Act. The breach statute does not set its own penalty amount.
Private right of action
No. The breach notification law itself doesn't give individuals a right to sue; the Attorney General enforces it. People can still bring other claims after a breach, such as negligence.
Encryption exemption
Mississippi's notification requirements apply to unencrypted personal information. Encrypted data generally doesn't trigger notice unless the encryption key or credentials were also compromised.
Liability protection for security programs
None. Mississippi has no law limiting breach lawsuits for organizations that maintain a security program.
Recent changes
None enacted in 2024–2026. Bills that would have required Attorney General notice (House Bill 1625 and Senate Bill 2479 in 2024, House Bill 731 and Senate Bill 2046 in 2025, and Senate Bill 2128 in 2026) all died in committee.
