Aon PLC

Aon is a global professional services firm that provides risk management, insurance brokerage, retirement consulting, and health solutions to a diverse range of clients. Its core offerings include advising organizations on risk transfer strategies, designing employee benefit programs, and delivering talent and rewards consulting. The firm serves corporations, public sector entities, and individual clients across various industries such as finance, manufacturing, technology, and healthcare. By combining insurance placement with advisory services, Aon aims to help clients protect assets, manage workforce risks, and optimize operational performance.

Aon’s headquarters is situated in the United Kingdom, anchoring its global network. The company maintains offices in dozens of countries, spanning North America, Europe, Asia‑Pacific, and the Middle East, which enables it to serve multinational clients locally. While exact employee figures are not stated in the provided sources, Aon is recognized as one of the largest insurance brokerage firms worldwide. Its international footprint allows the firm to draw on regional expertise while delivering consistent global standards.

Aon distinguishes itself by integrating traditional risk brokerage with advanced analytics, actuarial science, and human capital consulting. This combination enables the firm to offer insights that go beyond simple policy placement, such as predictive modeling of climate risk or workforce turnover. In addition to its core services, Aon has invested in technology platforms that support real‑time risk monitoring and digital claims processing. The firm’s profile has also been shaped by cybersecurity events, notably a 2023 data breach resulting from the exploitation of a vulnerability in the MOVEit Transfer file‑sharing tool, which was attributed to the Russia‑linked Clop ransomware group. A prior incident disclosed in February 2022 acknowledged a cybersecurity event without specifying the compromised data or responsible actor, reflecting the broader threat landscape faced by large professional services firms.

Structurally, Aon operates as an independent, publicly traded corporation. Its shares are listed on the New York Stock Exchange under the ticker symbol AON, and the company is not a subsidiary of another larger entity. Governance is overseen by a board of directors that includes representatives from various geographic regions and functional areas. This public‑company status subjects Aon to regular financial reporting and regulatory oversight in the jurisdictions where it operates. Collectively, these elements define Aon as a globally active risk and human capital solutions provider with a distinctive blend of advisory, brokerage, and technological capabilities.
