Southwire Discloses Data Breach Exposing Employee Health Plan Information
Carrollton-based wire manufacturer Southwire has notified employees that an unauthorized third party accessed files containing names, Social Security numbers, and medical information between November 2025 and January 2026. The company is offering two years of credit monitoring and identity protection services to those affected.
CARROLLTON, Ga. â Southwire, the Carrollton-based wire and cable manufacturer, has begun notifying employees and affiliates that a data security incident exposed private information tied to its health plans, the company announced Thursday.
According to the company, Southwire detected unusual activity on its systems at the end of January. It said it moved quickly to secure its environment and brought in outside cybersecurity specialists to investigate.
The investigation determined that an unauthorized third party had acquired certain files between November 2025 and January 2026. A further review to identify which files were affected took several months.
In late October, Southwire learned that the information taken varied by individual but may have included names, Social Security numbers, dates of birth, home addresses, health plan information and medical information. The compromised health plan data may also have included plan numbers.
Southwire said it is mailing letters to individuals it believes were impacted and is offering two years of complimentary credit monitoring and identity protection services.
The company said it has enhanced its technical and administrative controls and is evaluating additional steps to strengthen its systems and reduce the risk of similar incidents in the future.
"Southwire is not aware of any misuse of individuals' information as a result of this incident," the company said. "Nonetheless, the Plan recommends that individuals remain vigilant by reviewing account statements, credit reports, and other financial records for unusual activity."
Individuals who believe they may have been affected can call 1-833-931-3700 Monday through Friday from 8 a.m. to 8 p.m. Central Time. Callers should reference engagement number B175949.
The breach raises concerns about the protection of sensitive health data held by large employers. Southwire, one of Carroll County's largest employers, said it remains committed to safeguarding personal information in its care.
For a community built around a major manufacturer, the incident is a reminder of the stakes involved when private medical and financial records are compromised. Identity theft and medical fraud can take months to untangle, and experts recommend that anyone notified of a breach monitor their accounts closely and consider placing a fraud alert or credit freeze.
Southwire did not say how many individuals were affected.
