Background

What happened in the Lockton Companies data breach

According to its notice letter, Lockton, an insurance brokerage firm, experienced a cyber incident on August 11, 2026. The letter states that certain Lockton employees were the victims of a social engineering attack that resulted in an unauthorized individual obtaining access to those employee user accounts. Lockton says it activated its incident response procedures, engaged law enforcement and third-party cyber experts, and that the unauthorized access was confined to the affected employee accounts.

Lockton then reviewed the files to identify individuals whose personal information may have been contained within them. The notice letter is dated October 9, 2026, and the incident was reported in Massachusetts the same day. The Massachusetts filing lists names and driver's license numbers as the information involved. The posted sample letter says the information included the recipient's name and one or more other categories, but that list appears only as a placeholder. Lockton is offering a complimentary 24-month Experian IdentityWorks membership, with enrollment open through January 29, 2027.

Lockton has not disclosed a total number of affected individuals. The Massachusetts filing lists 7 Massachusetts residents, and the letter states that 1 Rhode Island resident was impacted. Whether Lockton's security practices met legal standards is among the issues being evaluated.
