What Is AIG?
AIG is the marketing name for American International Group, Inc.; AIG says its insurance products are written or provided by subsidiaries or affiliates. Its U.S. business pages list commercial casualty, property, cyber, management and professional liability, and specialty programs, but a brand-level page does not identify the insurer for a particular policy. 1,2
What Is Hiscox?
Hiscox suits eligible small businesses that want online GL, professional liability, cyber or BOP quotes; businesses needing other specialty products should compare brokers. Core Hiscox NOW policies are usually issued by its own insurer, while some products use partners. 4,5,6
What Is Professional Errors and Omissions (E&O) Insurance?
Professional liability can help pay defense costs and covered losses when a client says your advice or service caused financial harm. If customers rely on your work, list every service you provide and check the claims-made reporting and prior-work terms. 10,11,12,13
Key Differences in Professional Liability (E&O) Insurance
Profession-Specific Terms
AIG says its specialty E&O can be customized to a service provider’s work but does not promise eligibility for every profession. Hiscox offers separate E&O products for specific professions, letting a buyer start with a form designed for that occupation. A consultant should check whether Hiscox’s profession matches its services and ask AIG how the entity-specific wording addresses the same work. 3 7
Coverage and Claims Contact
AIG describes coverage for allegations of negligent professional services, including third-party economic loss. Hiscox describes its E&O coverage and explains how policyholders contact the company about claims. Compare each policy’s negligence definition, defense expenses and reporting deadline, then confirm whether the claims contact is the insurer or an agent. 3 8

Customer ratings for AIG are low: Trustpilot shows 1.9 out of 5 from 252 reviews, and NerdWallet gives 2.5 stars and notes more claims complaints than expected. These pages cover many AIG products and countries, so they only loosely describe business insurance.[1][2]
