# Marsh vs Relm Insurance Tech E&O Insurance

Marsh packages tech E&O into data-center programs; Relm sells a standalone Tech E&O product and a separate Fintech E&O variant.

## Research Scope and Use

Use this comparison to evaluate Marsh and Relm Insurance 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

Marsh brokers technology E&O as a professional-liability specialty and warns that off-the-shelf forms can miss data-center scale. Relm markets Tech E&O separately from cyber and offers Fintech E&O for blockchain and regulatory scrutiny.

## 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. [10](https://doas.ga.gov/sites/default/files/2025-08/SPD-SP048%20Insurance%20and%20Bonding%20Guidelines%20August%202025.pdf "Insurance and Bonding Guidelines") [11](https://www.thehartford.com/professional-liability-insurance/errors-omissions-insurance/technology "Technology Errors and Omissions Insurance") [12](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

### Broker Program Versus Relm Product

Marsh places technology E&O as a professional-liability specialty and as a component of data-center programs. Relm markets Technology Errors and Omissions as professional liability for the technology sector, sold through brokers, and keeps it distinct from the cyber product on the same page. Neither reviewed source names the issuing insurer. [6](https://www.marsh.com/en/services/financial-professional-liability/expertise/professional-liability.html "Professional liability") [5](https://www.marsh.com/en/industries/technology/expertise/data-center-insurance-and-risk-management-services.html "Data center insurance and risk management") [9](https://relminsurance.com/lines-of-business/cyber-and-technology-errors-and-omissions/ "Cyber and Technology Errors and Omissions")

### Data Centers Versus Software-Delivery Claims

Marsh’s data-center page focuses on gaps in conventional technology E&O at large, dense facilities and on combining E&O with property and casualty. Relm describes claims about inadequate service delivery, contractual failures, system failures or software glitches affecting customers, and negligent advice or failure to disclose product limitations. [5](https://www.marsh.com/en/industries/technology/expertise/data-center-insurance-and-risk-management-services.html "Data center insurance and risk management") [9](https://relminsurance.com/lines-of-business/cyber-and-technology-errors-and-omissions/ "Cyber and Technology Errors and Omissions")

### Fintech Variant

Relm offers a distinct Fintech Errors and Omissions product when standard Tech E&O is not enough for blockchain-related vulnerabilities and heightened regulatory scrutiny. Marsh’s reviewed pages do not describe a separate fintech E&O product; they name technology among specialized industries next to banking, insurance, asset management, media and healthcare. [9](https://relminsurance.com/lines-of-business/cyber-and-technology-errors-and-omissions/ "Cyber and Technology Errors and Omissions") [6](https://www.marsh.com/en/services/financial-professional-liability/expertise/professional-liability.html "Professional liability")

### Overlap With Cyber

Relm states that Tech E&O and cyber overlap but that one does not replace the other. Marsh’s reviewed professional-liability page does not spell out that overlap for this line; its data-center discussion is about combining E&O with property and casualty rather than with cyber. [9](https://relminsurance.com/lines-of-business/cyber-and-technology-errors-and-omissions/ "Cyber and Technology Errors and Omissions") [5](https://www.marsh.com/en/industries/technology/expertise/data-center-insurance-and-risk-management-services.html "Data center insurance and risk management") [6](https://www.marsh.com/en/services/financial-professional-liability/expertise/professional-liability.html "Professional liability")

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

- Identify the issuing insurer on both the Marsh placement and the Relm product. [6](https://www.marsh.com/en/services/financial-professional-liability/expertise/professional-liability.html "Professional liability") [9](https://relminsurance.com/lines-of-business/cyber-and-technology-errors-and-omissions/ "Cyber and Technology Errors and Omissions")
- If you operate a data center, ask Marsh how E&O is packaged; if you are fintech, ask Relm whether Fintech E&O applies. [5](https://www.marsh.com/en/industries/technology/expertise/data-center-insurance-and-risk-management-services.html "Data center insurance and risk management") [9](https://relminsurance.com/lines-of-business/cyber-and-technology-errors-and-omissions/ "Cyber and Technology Errors and Omissions")
- Confirm you are not treating Relm’s cyber product as a substitute for Tech E&O, or Marsh’s property/casualty layers as a substitute for E&O. [9](https://relminsurance.com/lines-of-business/cyber-and-technology-errors-and-omissions/ "Cyber and Technology Errors and Omissions") [5](https://www.marsh.com/en/industries/technology/expertise/data-center-insurance-and-risk-management-services.html "Data center insurance and risk management")
- Obtain limits and retentions; neither reviewed page publishes them for this line. [5](https://www.marsh.com/en/industries/technology/expertise/data-center-insurance-and-risk-management-services.html "Data center insurance and risk management") [9](https://relminsurance.com/lines-of-business/cyber-and-technology-errors-and-omissions/ "Cyber and Technology Errors and Omissions")
