Claims administration and risk management giant Sedgwick disclosed a cybersecurity incident at its federal contractor subsidiary, Sedgwick Government Solutions, on January 4, 2026. The company made the disclosure after the TridentLocker ransomware gang publicly claimed responsibility for stealing 3.4 GB of sensitive data.
The list of federal agencies using Sedgwick Government Solutions’ services includes the Cybersecurity and Infrastructure Security Agency (CISA), the Department of Commerce, the United States Citizenship and Immigration Services (USCIS), the United States Coast Guard, the Department of Homeland Security (DHS), the U.S. Department of Labor, the Customs and Border Protection (CBP), the Transportation Security Administration (TSA), the Federal Emergency Management Agency (FEMA), and the U.S. Coast Guard.
Sedgwick responded to the incident by immediately activating its incident response protocols with the support of external cybersecurity experts. The company added that Sedgwick Government Solutions is segmented from the rest of its business, and no wider Sedgwick systems or data were affected.
Sedgwick employs 33,000 employees and serves 10,000 clients across 80 countries, including 59% of the Fortune 500, and its subsidiary serves over 20+ government agency clients.
