Diversified Services Enterprises, Inc. (DSE), a Sarasota, Florida-based provider of support management services to healthcare organizations, discovered suspicious activity in its network on April 14, 2025. A subsequent investigation, assisted by third-party forensic specialists, determined that unauthorized parties accessed and copied files from the company's systems between March 14, 2025, and April 14, 2025. DSE took steps to secure its environment and began a review to identify the compromised information.
The breach exposed a wide range of sensitive information. This included names, dates of birth, addresses, Social Security numbers, driver’s license or state ID numbers, passport numbers, taxpayer identification numbers, financial account information, and payment card information. Additionally, the breach involved medical record numbers, Medicare/Medicaid IDs, health insurance information, and medical history information, such as mental or physical conditions, treatment, diagnosis, and provider details. Public reporting indicates the breach affected hundreds of individuals, but an exact total remains unconfirmed from accessible sources.
DSE reportedly posted a notice on its website on June 13, 2025, which was later updated on September 10, 2026. The company also reported the incident to the U.S. Department of Health and Human Services on June 13, 2025. Information regarding specific state attorney general filings, the number of individuals notified, or state-by-state impact has not been publicly detailed. A consumer-law site is tracking a 'DSE Data Breach Lawsuit Investigation,' suggesting potential litigation, but a filed complaint has not been confirmed.
