## What Is Crime Insurance?

Crime insurance can help reimburse specified business losses from theft and fraud, including employee theft and forgery. Compare those protections separately and ask whether a payment sent after an impersonation scam is covered. [10](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [11](https://www.travelers.com/business-insurance/professional-liability-insurance/apps-forms/crime-non-financial-institutions "Crime Non-Financial Applications and Forms") [12](https://asset.trvstatic.com/download/assets/cri-3001.pdf/98f30f1063c911eeb2f1deb19c93b21f "Crime Terms and Conditions") [13](https://www.chubb.com/us-en/business-insurance/social-engineering-fraud-coverage-for-crime-insurance.html "Social Engineering Fraud Insurance") [14](https://asset.trvstatic.com/download/assets/cri-1100w-ind.pdf/9aa2577663c911ee91291279531924d3 "Commercial Crime Coverage Application")

## Key Differences in Crime Insurance

### Coverage and Audience

Marsh lists employee white-collar fraud, third-party fraud, collusion, computer-related crime, social engineering and tangible-asset theft as risks a commercial crime policy can address. Marsh McLennan Agency names crime and fidelity but does not itemize the events. Buyers can use Marsh’s list to ask whether Marsh McLennan Agency’s proposed wording includes collusion and social engineering. [5](https://www.marsh.com/en/services/financial-professional-liability/expertise/commercial-crime-insurance.html "Commercial crime insurance") [9](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA")

### Terms and Buyer Support

Marsh says its specialists handle complex placements around $10 million to $110 million and offer infill or top-up social-engineering cover above an existing program; these are experience examples, not a published limit promise. Marsh McLennan Agency provides no standard limits in its overview. If an existing program has a gap, ask whether Marsh McLennan Agency can source excess social-engineering cover. [5](https://www.marsh.com/en/services/financial-professional-liability/expertise/commercial-crime-insurance.html "Commercial crime insurance") [9](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA")

### Placement and Claims Process

Marsh and Marsh McLennan Agency both describe adviser-led placement rather than online quoting. Marsh says its team provides market and claim examples through renewal and placement, while Marsh McLennan Agency’s overview does not describe these services. Ask Marsh McLennan Agency what placement education and renewal support are included. [5](https://www.marsh.com/en/services/financial-professional-liability/expertise/commercial-crime-insurance.html "Commercial crime insurance") [9](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA")

## What to Confirm in Crime Insurance Quotes

- Ask Marsh whether infill social-engineering cover can sit above your current policy and what its scope is. Ask Marsh McLennan Agency for limits, service scope and the actual crime agreements. [5](https://www.marsh.com/en/services/financial-professional-liability/expertise/commercial-crime-insurance.html "Commercial crime insurance") [9](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA")

## Offering Details

| Criteria | Marsh Commercial Crime Insurance Brokerage | Marsh McLennan Agency crime (official overview) |
| --- | --- | --- |
| Role in This Line | Marsh's financial and professional liability practice places commercial crime insurance; Marsh McLennan Agency (MMA), the middle-market subsidiary, also places crime coverage bundled with fidelity as part of its executive and professional liability practice. [5](https://www.marsh.com/en/services/financial-professional-liability/expertise/commercial-crime-insurance.html "Commercial crime insurance") [6](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Expert Executive and Professional Liability Insurance") (Evidence: Company-reported; scope: Marsh corporate commercial crime page and MMA executive and professional liability page..) | Marsh McLennan Agency describes arranging crime for the audience stated on the cited product page.

This is not a policy form or a universal eligibility statement..) |
| Issuing Insurer | The reviewed pages do not name a specific crime insurer. Marsh says definitions and extensions for crime coverage differ across insurers and that it works to secure coverage aligned with a client's risks, implying the carrier varies by placement. [5](https://www.marsh.com/en/services/financial-professional-liability/expertise/commercial-crime-insurance.html "Commercial crime insurance") (Evidence: Not publicly disclosed; scope: Commercial crime insurance page as read on 2026-09-23..) | Confirm in your quote. |

This is not a policy form or a universal eligibility statement..) |
| Coverage Features | Marsh lists employee white-collar fraud (including fidelity losses from trusted employees), third-party fraud, collusion, hacking or computer-related crime, social engineering fraud, and tangible asset theft as risks a commercial crime policy can address. It notes that crime policies usually exclude ransomware, though most cover direct financial losses from funds stolen by hackers. [5](https://www.marsh.com/en/services/financial-professional-liability/expertise/commercial-crime-insurance.html "Commercial crime insurance") (Evidence: Company-reported; scope: Commercial crime insurance page; the page is Marsh's global/UK financial-professional-liability practice content and cites a UK-based crime leader, so figures and coverage descriptions may not reflect a US-specific program..) | The cited product page describes commercial crime/fidelity as a named executive and professional liability product; the overview does not specify insured events or terms. Marketing description only; actual coverage, exclusions, conditions, limits, and availability depend on the issued policy and jurisdiction. [9](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA") (Evidence: Company-reported; scope: crime marketed by marsh-mclennan-agency; scope is limited to the cited official product overview and described audience. This is not a policy form or a universal eligibility statement..) |
| Limits and Retentions | Marsh says its team has experience handling complex crime placements ranging from about $10 million to $110 million (also stated in GBP as £10 million to £100 million elsewhere on the page), but does not publish standard limits, retentions or premiums for a specific placement. [5](https://www.marsh.com/en/services/financial-professional-liability/expertise/commercial-crime-insurance.html "Commercial crime insurance") (Evidence: Company-reported; scope: Commercial crime insurance page; a description of Marsh's placement experience range, not a quoted limit for any individual buyer..) | The cited overview does not set a universal limit or retention for this line. Ask for the proposed policy form, limits, retentions, exclusions, and conditions in the quote. [9](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA") (Evidence: Not publicly disclosed; scope: Only the cited marketing page was reviewed for published limit and retention information; no policy-form entitlement is inferred..) |
| Risk Services | Marsh says it provides insights on emerging crime risks, claim examples, market conditions and product education throughout renewal and placement, and offers infill and top-up social engineering cover in excess of a client's existing program. [5](https://www.marsh.com/en/services/financial-professional-liability/expertise/commercial-crime-insurance.html "Commercial crime insurance") (Evidence: Company-reported; scope: Commercial crime insurance page, Why Marsh section..) | Confirm in your quote. |
| How to Apply | You engage Marsh's crime specialists (Marsh corporate or MMA) directly to identify crime exposure and place coverage; the reviewed pages describe advisor-led placement rather than an online quote tool. [5](https://www.marsh.com/en/services/financial-professional-liability/expertise/commercial-crime-insurance.html "Commercial crime insurance") [6](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Expert Executive and Professional Liability Insurance") (Evidence: Company-reported; scope: Commercial crime insurance and MMA executive and professional liability pages..) | The page invites organizations to contact a Marsh McLennan Agency adviser or specialist to discuss placement.
