Sullivan Environmental Services, Inc., a Galveston, Texas-based company, recently notified the Texas Attorney General’s office of a data security incident affecting hundreds of individuals. The filing confirms that personal information, including Social Security numbers and financial account details, was involved.
Companies that collect and store sensitive personal information have a legal and ethical responsibility to safeguard it, and to notify affected individuals promptly when that information is compromised.
Sullivan Environmental Services, Inc.’s Data Breach Investigation
According to a report filed with the Texas Attorney General’s office and published on August 4, 2026, Sullivan Environmental Services, Inc. disclosed a data security incident affecting 399 Texas residents. The filing indicates that the exposed information included individuals’ names, Social Security numbers, driver’s license numbers, financial account or payment card information, and health insurance information. The company reported that notice was provided to affected individuals by U.S. Mail. As is common with many entries in the Texas Attorney General’s breach reporting database, the filing does not disclose the specific cause of the incident, the dates on which the breach occurred or was detected, or additional narrative detail beyond the categories of information involved and the number of Texans affected.
Texas law requires any business that experiences a breach affecting 250 or more Texas residents to submit a report to the Attorney General’s office, which then publishes certain details in a public database. This regulatory framework is designed to give consumers visibility into incidents that may affect them, even when the responsible company has not issued a detailed public statement. Environmental services and remediation companies, like many small and mid-sized businesses, often maintain sensitive records on clients, employees, and vendors, including financial and health-related information tied to insurance or workers’ compensation matters, making them attractive targets for cybercriminals despite not being a traditional high-profile target sector.
The combination of Social Security numbers, driver’s license numbers, and financial account information is particularly valuable to identity thieves. With this data, criminals can attempt to open new lines of credit, file fraudulent tax returns, apply for loans, or gain access to existing financial accounts in a victim’s name. When health insurance information is also involved, there is an additional risk of medical identity theft, where a criminal uses a victim’s insurance details to obtain medical services or prescriptions, potentially resulting in inaccurate medical records or unexpected bills for the victim.
When Did This Breach Occur?
Sullivan Environmental Services, Inc.’s report to the Texas Attorney General was published on August 4, 2026. The filing does not specify the exact dates on which the breach occurred or was discovered, which is common in filings that provide only the categories of compromised data and confirmation that notice was sent to affected individuals.
