## Summary

AIG describes entity E&O for negligent professional services; Markel publishes professional-liability coverage, appetite, limits and application information for its target businesses. [3](https://www.aig.com/home/risk-solutions/business/management-and-professional-liability/professional-liability "Professional Liability Insurance") [6](https://www.markel.com/us/commercial/professional-and-management-liability/probiz "ProBiz | Professional Liability Coverage")

## 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)

## Markel Insurance: Specialty Business and Products

Markel Insurance is Markel Group's specialty and small-business insurance business, with offerings across packages, workers' compensation, cyber, professional and management liability, property, marine, and surety. Products use different insurers and distribution routes, so compare the issuer and terms shown on the specific quote. [4](https://www.markel.com/about-us "About us") [5](https://www.sec.gov/Archives/edgar/data/1096343/000109634326000020/mkl-20251231.htm "Markel Group Inc. 2025 Form 10-K")

## 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. [7](https://www.tdi.texas.gov/commercial/pl-faq.html "FAQ: Professional liability insurance") [8](https://www.iii.org/article/professional-liability-insurance "Professional liability insurance") [9](https://www.sba.gov/counseling/launch-your-business/#business-insurance "Get business insurance") [10](https://www.hiscox.com/documents/pl-sample-policy-wording.pdf "Professional Liability – US Direct Errors and Omissions Insurance")

## Key Differences in Professional Liability (E&O) Insurance

### Appetite and Application

AIG describes a broad service-provider audience and says the policy can be customized, without confirming every profession. Markel publishes target classes for professional liability and an application route, giving buyers specific appetite checkpoints. If your occupation is among Markel’s classes, ask whether the particular service is accepted; if not, AIG still needs to review the full work description. [3](https://www.aig.com/home/risk-solutions/business/management-and-professional-liability/professional-liability "Professional Liability Insurance") [6](https://www.markel.com/us/commercial/professional-and-management-liability/probiz "ProBiz | Professional Liability Coverage")

### Limits and Policy Scope

AIG describes intended protection for negligent professional services and third-party economic loss but gives no standard limit in its reviewed record. Markel publishes limit information for its professional-liability offering. Compare the quote’s limit basis, retention and defense-cost treatment with the allegation scope in each form; published capacity does not guarantee an individual quote. [3](https://www.aig.com/home/risk-solutions/business/management-and-professional-liability/professional-liability "Professional Liability Insurance") [6](https://www.markel.com/us/commercial/professional-and-management-liability/probiz "ProBiz | Professional Liability Coverage")

## What to Confirm in Professional Liability (E&O) Insurance Quotes

- Ask AIG for quoted limits, retention and the covered-services wording. [3](https://www.aig.com/home/risk-solutions/business/management-and-professional-liability/professional-liability "Professional Liability Insurance")
- Ask Markel whether your class qualifies and whether its published limit maximum is available for your requested coverage. [6](https://www.markel.com/us/commercial/professional-and-management-liability/probiz "ProBiz | Professional Liability Coverage")

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.
