Southern Company, the parent of Georgia Power, faces a class-action lawsuit after a data breach exposed information from approximately 400,000 utility accounts. The breach was disclosed in early October 2026, revealing that unauthorized access occurred through the company's online customer portal. The lawsuit, filed by a Georgia resident, alleges inadequate protection of customer data, including names, addresses, and the last four digits of Social Security numbers. Southern Company has stated that no bank account numbers or payment card information was accessed. The company is currently investigating the incident and has offered affected customers one year of free credit monitoring. This lawsuit marks at least the third class-action complaint related to the breach filed in federal court this month. Southern Company has not confirmed ongoing unauthorized access but is cooperating with law enforcement.
