Aon is a global professional services firm that primarily brokers insurance and reinsurance — meaning it connects businesses with insurers and negotiates coverage on their behalf, earning commissions and fees. It also sells human resources consulting services, including employee benefits administration and retirement advisory. Customers are mostly mid-to-large corporations and institutions worldwide. Revenue comes mainly from brokerage commissions and advisory fees rather than underwriting risk itself.
