# Marsh vs Relm Insurance: How Do They Compare for Tech E&O Insurance?

Relm Insurance markets tech E&O as professional liability for the technology sector, separate from cyber, with a distinct fintech version; Marsh handles it through professional liability experts and data center programs that include property and casualty.

Marsh builds tech E&O into data-center programs with property and casualty, while Relm sells standalone tech E&O plus a separate Fintech E&O product for blockchain and regulatory exposures.

## Marsh vs Relm Insurance Tech E&O Insurance Summary

Data-center operators should look at Marsh, which combines tech E&O with property and casualty because standard forms miss data-center scale. Fintech and blockchain companies should look at Relm, which sells a dedicated Fintech E&O product alongside its standard tech E&O.

## What Are the Key Differences Between Marsh and Relm Insurance Tech E&O Insurance?

### Data-Center Programs vs a Fintech-Specific Form

Marsh places tech E&O as a professional-liability specialty and as part of data-center programs, warning that off-the-shelf forms can leave gaps at large, dense facilities, so it combines E&O with property and casualty. Relm sells tech E&O through brokers and offers a separate Fintech E&O product because standard tech E&O isn’t always enough for blockchain vulnerabilities and regulatory scrutiny. Choose Marsh if you run a data center or need tech E&O coordinated with a large property program; choose Relm if you are a fintech or blockchain company. [2](https://www.marsh.com/en/services/financial-professional-liability/expertise/professional-liability.html "Professional liability") [1](https://www.marsh.com/en/industries/technology/expertise/data-center-insurance-and-risk-management-services.html "Data center insurance and risk management") [3](https://relminsurance.com/lines-of-business/cyber-and-technology-errors-and-omissions/ "Cyber and Technology Errors and Omissions")

### Program Gaps vs Software-Delivery Claims

Relm describes the claims its tech E&O answers: poor service delivery or contract failures, system failures or software glitches that hit customers, and negligent advice or failure to disclose product limitations. It also warns that tech E&O and cyber overlap but neither replaces the other. Marsh focuses on program design rather than listing claim types. Neither names an insurer or publishes limits.

- If you run a data center, ask Marsh how E&O fits with your property and casualty; if you are a fintech, ask Relm whether Fintech E&O applies.
