## Research Scope and Use

Use this comparison to evaluate AIG and Marsh for Commercial Property Insurance against the same documented criteria. It identifies differences and questions to confirm; it does not select a winner for a particular business.

## Summary

AIG lists varied property clients and a dedicated claims team. Marsh describes property protection for assets and specialized data-center programs that coordinate equipment breakdown, interruption, cyber, and liability. [3](https://www.aig.com/home/risk-solutions/business/commercial-property "Commercial Property Insurance") [8](https://www.marshmma.com/us/solutions/property.html "Property Insurance") [9](https://www.marsh.com/en/industries/technology/expertise/data-center-insurance-and-risk-management-services.html "Data Center Insurance and Risk Management Services")

## 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 Marsh?

Marsh suits technology and larger businesses seeking specialist cyber placement or broad global risk advice; small firms wanting a quick standard quote should compare its MMA route or digital agencies. [4](https://www.marsh.com/en/home.html "Marsh | Leader in risk, strategy, people, and investments") [5](https://www.marsh.com/content/dam/marsh/Documents/PDF/US-en/us-client-compensation-guide.pdf "Compensation guide for US clients") [6](https://www.marsh.com/en/services/marsh-mclennan-agency.html "Marsh McLennan Agency (MMA)") [7](https://www.marsh.com/en/industries/technology.html "Technology | Insurance Broking & Risk Management")

## What Is Commercial Property Insurance?

Commercial property may fit your business if you own a building or rely on equipment and stock. Compare replacement-cost terms, deductibles and any coinsurance condition, and check lost-income protection separately. [10](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [11](https://content.naic.org/cipr-topics/business-interruptionbusinessowners-policies-bop "Business Interruption Insurance/Businessowner’s Policies (BOP)") [12](https://www.tdi.texas.gov/pubs/consumer/cb021.html "Commercial property insurance guide")

## Key Differences in Commercial Property Insurance

### Corporate property insurance and specialist placement programs

AIG names hospitals, universities, and global manufacturers among its property audiences and describes a dedicated Property claims team. Marsh McLennan Agency places property for middle-market clients, while Marsh’s technology practice arranges coverage for data centers. For data-center operators, the specialist placement matters because the property program may need to account for digital infrastructure exposures beyond the building itself. [3](https://www.aig.com/home/risk-solutions/business/commercial-property "Commercial Property Insurance") [8](https://www.marshmma.com/us/solutions/property.html "Property Insurance")

### Data-center coverage coordination

Marsh says data-center property coverage is typically paired with equipment breakdown, business interruption, cyber, and general liability to address gaps a conventional property policy alone may leave. Its broader property practice also offers valuation, catastrophe modeling, claims advocacy, risk control, captives, and parametric options. AIG describes property protection and claims service, but its public record here does not lay out that data-center package. Ask for the coordinated terms, including dependencies between coverages, in either quote. [3](https://www.aig.com/home/risk-solutions/business/commercial-property "Commercial Property Insurance") [8](https://www.marshmma.com/us/solutions/property.html "Property Insurance")

## What to Confirm in Commercial Property Insurance Quotes

- Ask AIG how equipment breakdown, interruption, and cyber interact with the property policy for a data center. [3](https://www.aig.com/home/risk-solutions/business/commercial-property "Commercial Property Insurance")
- Ask Marsh which policies are bundled or coordinated, who issues each one, and what limits and exclusions apply. [8](https://www.marshmma.com/us/solutions/property.html "Property Insurance")

## Offering Details

| Criteria | AIG Commercial Property and Retail Property | Marsh McLennan Agency Commercial Property Insurance |
| --- | --- | --- |
| Role in This Line | AIG markets commercial property insurance and identifies Retail Property as a product area. For domestic and global corporate and risk-management clients, the page describes both risk-transfer insurance and non-risk-transfer fronting or captive solutions; those structures are not the same as an insurance policy issued by AIG. [3](https://www.aig.com/home/risk-solutions/business/commercial-property "Commercial Property Insurance") (Evidence: Company-reported; scope: AIG’s U.S. Commercial Property page.

| Coverage Features | AIG describes commercial property insurance as protecting business physical property against unexpected events such as storm damage, theft and vandalism, and says coverage can extend to certain work-related contents such as office equipment, furniture, fixtures and inventory. These are examples; actual coverage depends on the facts and each policy’s terms, conditions and exclusions. [3](https://www.aig.com/home/risk-solutions/business/commercial-property "Commercial Property Insurance") (Evidence: Company-reported; scope: General property description on AIG’s product page, not a summary of a specific policy or all covered causes of loss..) | MMA says commercial property insurance protects an organization's physical assets, including owned or rented property, equipment and inventory, from unexpected loss events, with named options for flood, hurricane and windstorm, wildfire and earthquake coverage.

| Risk Services | AIG says property risk engineers help clients identify and mitigate loss and that its engineers collaborate with clients on solutions tailored to risk factors. The page does not state that these services are included for every account or guarantee reduced losses. [3](https://www.aig.com/home/risk-solutions/business/commercial-property "Commercial Property Insurance") (Evidence: Company-reported; scope: Company-described commercial property risk engineering; account-specific service availability is not stated..) | MMA says its property practice offers hazard assessment and valuation services, loss and catastrophe modeling, claims advocacy, pre- and post-loss risk control, and alternative risk solutions such as captives and parametric insurance options.

## AIG Reviews

Review Score: 4.4 / 10 from 2 rated sources, equally weighted.

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). NerdWallet’s editorial business-insurance comparison; the AIG entry concerns commercial liability and property insurance, not a quantified policyholder-review sample.
