[3](https://www.aig.com/home/risk-solutions/business/casualty/excess-casualty "Excess Casualty Insurance") [7](https://joinalliancerisk.com/umbrella-excess-liability-insurance/ "Umbrella & Excess Liability Insurance") ## 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](https://www.aig.com/investor-relations "Investor Relations") [2](https://www.aig.com/home/risk-solutions/business "Business") [AIG profile](https://spot.insure/insurance-providers/aig) ## What Is Alliance Risk? Alliance Risk suits tech startups from pre-seed through IPO that want a broker to review their tech E&O policy for free and shop specialist insurers; if you want to buy online in minutes, use a digital insurer. Quotes take 24 hours to ten business days, depending on your risk.

Umbrella or excess insurance adds liability limits above the policies named in the quote after a covered claim exhausts their limits. It may fit if a contract sets higher limits; check which primary policies are listed and any gaps between them.

Alliance Risk describes typical limits starting at $1 million and reaching $25 million or more, while distinguishing umbrella’s potential to broaden some terms from excess coverage that follows underlying wording. Buyers should compare attachment points and follow-form language, not just top-line capacity. [3](https://www.aig.com/home/risk-solutions/business/casualty/excess-casualty "Excess Casualty Insurance") [7](https://joinalliancerisk.com/umbrella-excess-liability-insurance/ "Umbrella & Excess Liability Insurance") ### Capacity and account support Alliance Risk recommends reviewing limits as the business grows and modeling catastrophic loss, alongside vendor and subcontractor risk transfer. AIG describes in-house risk experts, claims specialists, and integration with domestic and foreign casualty platforms. Ask how either placement fits existing underlying policies and which team will model a multi-layer tower. [3](https://www.aig.com/home/risk-solutions/business/casualty/excess-casualty "Excess Casualty Insurance") [7](https://joinalliancerisk.com/umbrella-excess-liability-insurance/ "Umbrella & Excess Liability Insurance") ## What Should You Confirm in AIG and Alliance Risk Umbrella and Excess Liability Insurance Quotes? - Ask AIG which position, attachment point, and legal insurer apply to the proposed tower. [3](https://www.aig.com/home/risk-solutions/business/casualty/excess-casualty "Excess Casualty Insurance") - Ask Alliance Risk to identify underlying policies, limits, and follow-form terms.

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. - NerdWallet: NerdWallet editorial rating 2.5 (stars).
