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 ⁵ ⁹

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 ⁹

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 ⁶

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 ⁵ ⁶

What to Confirm in Tech E&O Insurance Quotes

Identify the issuing insurer on both the Marsh placement and the Relm product. ⁶ ⁹
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 ⁹
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 ⁵
Obtain limits and retentions; neither reviewed page publishes them for this line. ⁵ ⁹

Criteria	Marsh Technology Errors and Omissions Insurance	Relm Technology Errors and Omissions Insurance

Marsh professional liability page and data-center insurance page.	Relm markets Technology Errors and Omissions as professional liability for the technology sector, separate from the cyber liability product on the same page. ⁹Company-reported.

Issuing Insurer	The reviewed pages do not name a specific technology E&O insurer. ^6,⁵Not publicly disclosed. Marsh professional liability and data-center insurance pages as read on 2026-09-23.	The reviewed page does not name a specific issuing insurer for Tech E&O placements. ⁹Not publicly disclosed. Line-of-business page as read on 2026-09-23; a specific placement's insurer is product- and jurisdiction-specific.
Who It’s For	Marsh names technology among the specialized industries its professional liability (E&O) experts serve, alongside banking, insurance and asset management, media and healthcare. ⁶Company-reported. Marsh professional liability page, What We Offer section.	Relm says a business is exposed if it delivers software or tech services, citing risks from AI models making biased decisions, model theft, or data poisoning as examples of the kinds of claims that can arise. ⁹Company-reported. Cyber and Tech E&O page framing; not a guarantee of eligibility for a particular company.
Coverage Features	Marsh says off-the-shelf technology E&O policies were not built for the scale and concentration of modern data centers and can leave gaps. It designs data center programs that combine technology E&O with property, casualty and other lines. ⁵Company-reported. Data center insurance page, Closing the gaps in conventional coverage section; describes a gap in standard tech E&O for one customer segment (data centers), not the general product.	Relm says Tech E&O covers claims relating to inadequate service delivery or failure to meet contractual obligations, system failures or software glitches affecting customers' operations, and negligent advice, misrepresentation or failure to disclose product limitations, typically including legal defense fees, settlements and judgments. ⁹Company-reported. Cyber and Tech E&O page 'What is Tech E&O Insurance?' section; the issued policy and declarations control. Relm says standard Tech E&O is not always sufficient for fintech companies and offers a distinct Fintech Errors and Omissions product addressing blockchain-related vulnerabilities and heightened regulatory scrutiny. ⁹Company-reported. Cyber and Tech E&O page 'What is Fintech Errors and Omissions Insurance?' section; a related but separate product. Relm explicitly says there is some overlap between Tech E&O and cyber coverage, but having one does not protect a client from the exposures the other addresses. ⁹Company-reported. Cyber and Tech E&O page 'Who Needs Cyber and Tech E&O Insurance?' section.
