Lockton Data Breach Lawsuit Investigation
Received an April 2026 breach notice from Lockton?
Dapeer Law, P.A. is investigating a potential class action against Lockton Companies, LLC, the world's largest privately held insurance brokerage and risk-management firm, on behalf of Dexcom employees whose personal information may have been exposed in an April 2026 data incident.
Who may qualify
You may be eligible to participate in a class action if any of the following applies:
- You received a data breach notification letter from Lockton dated April 2026.
- Your letter offered enrollment in free Experian IdentityWorks credit monitoring (Experian).
- You are a Dexcom employee whose personal information Lockton held in its capacity as Dexcom's insurance broker.
- No proof of harm required to consult with counsel. You do not need to have already suffered identity theft to explore your legal options.

What happened
On April 29, 2026, the West Series of Lockton Companies, LLC ("Lockton"), acting as insurance broker for Dexcom, circulated a request for proposal (RFP) to three potential vendors. An Excel file attached to the RFP inadvertently contained additional personal information belonging to Dexcom employees that was not intended to be shared.
Lockton states it revoked the three vendors' access to the file shortly after the disclosure, and that each vendor either confirmed the file was never opened or that it had been promptly deleted. Lockton began mailing notification letters on or around June 12, 2026 and filed notice with the California Attorney General. According to the notice, the file contained Social Security numbers, first and last names, dates of birth, and limited benefits election information. Lockton is offering 24 months of complimentary credit monitoring through Experian IdentityWorks.
Because the exposed information included Social Security numbers and dates of birth, affected individuals may face an elevated risk of identity theft and financial fraud. Whether Lockton's data-handling and vendor controls met legal standards, and whether the vendors' attestations fully resolve the exposure, are among the issues being evaluated.

Data breach class action recoveries vary significantly. Settlements typically range from a few hundred dollars for basic out-of-pocket losses to several thousand dollars for documented identity theft, with class size, damages, and negotiation all affecting the final amount.
