    Ransomware incident affecting internal systems

    In September 2020, Gallagher reported that ransomware had affected certain internal systems. The company took global systems offline as a precaution, began an investigation, hired external cybersecurity professionals, initiated response protocols, and activated business-continuity plans. It later stated that most business systems had been restarted or were in the process of restarting.
