Wyoming data breach notification law

What Wyoming requires when personal information is exposed: how fast residents must be notified, when the Attorney General has to be told, what it costs to get it wrong, and whether affected people can sue. Governed by Wyo. Stat. §§ 40-12-501 and 40-12-502.

What this means if you sell security services

Wyoming 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 Wyoming 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
Wyo. Stat. §§ 40-12-501 and 40-12-502
Deadline to notify residents
As soon as possible, in the most expedient time possible and without unreasonable delay, after a prompt investigation shows that misuse has occurred or is reasonably likely. Timing may account for law enforcement needs and for measures needed to determine the scope of the breach, and notice may be delayed if law enforcement determines in writing that it would seriously impede a criminal investigation.
Attorney General notification
No. The statute does not require notice to the Attorney General or to consumer reporting agencies.
Penalties
The Attorney General may bring an action to address violations, obtain relief to ensure compliance, and recover damages. The statute sets no specific civil 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
Wyoming'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. Wyoming has no law limiting breach lawsuits for organizations that maintain a security program.
