# Coalition vs Marsh Tech E&O Insurance

Coalition pairs Tech E&O with its cyber product; Marsh treats the line as a professional-liability specialty and a data-center building block.

## Research Scope and Use

Use this comparison to evaluate Coalition and Marsh for Tech E&O Insurance against the same documented criteria. It identifies differences and questions to confirm; it does not select a winner for a particular business. Offering claims are what each provider publishes about this line unless marked otherwise. “Not found” describes the evidence reviewed, not proof that a feature is unavailable. Confirm the insurer, policy wording, limits, retentions, exclusions and cost in an actual quote.

## Summary

Coalition distributes Tech E&O only with Active Cyber Insurance. Marsh brokers technology E&O as a financial and professional specialty and warns that off-the-shelf forms can leave gaps for large data centers.

## What Is Coalition Insurance?

Coalition offers cyber insurance and technology E&O alongside cyber risk-management services. Its U.S. products are distributed through insurance producers, with separate admitted and surplus-lines routes and an executive-risk product suite.

## What Is Technology Errors and Omissions (E&O) Insurance?

Technology errors and omissions (E&O) insurance addresses claims that a technology product or service caused a customer or other third party a financial loss. It doesn't extend to cyber incidents, bodily injury or professional services outside the quoted product. [13](https://doas.ga.gov/sites/default/files/2025-08/SPD-SP048%20Insurance%20and%20Bonding%20Guidelines%20August%202025.pdf "Insurance and Bonding Guidelines") [14](https://www.thehartford.com/professional-liability-insurance/errors-omissions-insurance/technology "Technology Errors and Omissions Insurance") [15](https://www.chubb.com/content/dam/chubb-sites/chubb-com/us-en/business-insurance/digitech-enterprise-risk-management-digitech-erm/documents/pdf/17010186-digitech-erm-12.17.pdf "DigiTech Enterprise Risk Management")

## Key Differences in Tech E&O Insurance

### Program Role

Coalition designs and distributes Tech E&O that must combine with Active Cyber Insurance and is sold through appointed brokers. Marsh treats technology E&O as one of its financial and professional liability specialties and also names it as a building block inside data-center insurance programs, placing coverage rather than issuing Coalition’s combined form. [1](https://www.coalitioninc.com/technology-errors-and-omissions-insurance "Tech E&O Insurance Coverage") [12](https://www.marsh.com/en/services/financial-professional-liability/expertise/professional-liability.html "Professional liability") [11](https://www.marsh.com/en/industries/technology/expertise/data-center-insurance-and-risk-management-services.html "Data center insurance and risk management")

### Data-Center Scale Versus a Standard Tech Fee Model

Coalition’s reviewed page speaks to any organization that sells a technology product or service for a fee, with examples such as downtime and failed technology services. Marsh’s data-center page says off-the-shelf technology E&O policies were not built for the scale and concentration of modern data centers and can leave gaps, so it designs programs that combine technology E&O with property, casualty and other lines. [1](https://www.coalitioninc.com/technology-errors-and-omissions-insurance "Tech E&O Insurance Coverage") [11](https://www.marsh.com/en/industries/technology/expertise/data-center-insurance-and-risk-management-services.html "Data center insurance and risk management")

### Service Overlay

Coalition says the same Control platform used on cyber policies is included with Tech E&O, plus one in-house claims team for both lines. Marsh’s reviewed professional-liability and data-center pages do not describe an equivalent monitoring platform attached to every technology E&O placement. [6](https://www.coalitioninc.com/control "Coalition Control") [1](https://www.coalitioninc.com/technology-errors-and-omissions-insurance "Tech E&O Insurance Coverage") [12](https://www.marsh.com/en/services/financial-professional-liability/expertise/professional-liability.html "Professional liability")

## What to Confirm in Tech E&O Insurance Quotes

- Ask Marsh whether your placement is a standalone professional-liability form or part of a data-center tower with property and casualty. [11](https://www.marsh.com/en/industries/technology/expertise/data-center-insurance-and-risk-management-services.html "Data center insurance and risk management")
- Confirm Coalition will not bind Tech E&O without Active Cyber Insurance. [1](https://www.coalitioninc.com/technology-errors-and-omissions-insurance "Tech E&O Insurance Coverage")
- Get both issuing insurers in writing; neither Coalition’s Tech E&O disclaimer section nor Marsh’s reviewed pages name the carrier. [5](https://www.coalitioninc.com/legal/disclaimer "U.S. Disclaimers") [12](https://www.marsh.com/en/services/financial-professional-liability/expertise/professional-liability.html "Professional liability")
- If you operate a data center, ask Marsh which gaps in a standard Tech E&O form the program is meant to close. [11](https://www.marsh.com/en/industries/technology/expertise/data-center-insurance-and-risk-management-services.html "Data center insurance and risk management")
