The company operates primarily in the insurance brokerage, reinsurance brokerage, human capital consulting, and wealth advisory industries. Its core revenue drivers include commissions and fees generated through commercial risk advisory services, reinsurance solutions, health and benefits consulting, retirement consulting, and data-driven analytics services.

The company positions itself as a global adviser helping clients manage volatility, workforce challenges, and capital allocation risks through proprietary data, analytics, and advisory tools. Aon traces its origins to the 1982 merger of Ryan Insurance Group and Combined International Corporation under founder Patrick G. Ryan. Over time, the company expanded through acquisitions and global brokerage consolidation, including the acquisition of Hewitt Associates in 2010 and NFP Corp. in 2024. Aon is incorporated in Ireland and publicly traded on the New York Stock Exchange under the ticker AON.
