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

Technology errors and omissions coverage can help pay when a customer claims your software, hosting, installation or technology advice caused financial loss. If you provide tech products or services, check each activity; cyber incidents and unrelated professional work need separate review. [10](https://content.naic.org/glossary-insurance-terms "Glossary of Insurance Terms") [11](https://doas.ga.gov/sites/default/files/2025-08/SPD-SP048%20Insurance%20and%20Bonding%20Guidelines%20August%202025.pdf "Insurance and Bonding Guidelines") [12](https://online.ogs.ny.gov/purchase/snt/awardnotes/7360022802AppendixJ_PRB01.pdf "Appendix J – Contractor’s Insurance Requirements, Information Technology Umbrella Contract – Manufacturer Based (Statewide)") [13](https://www.thehartford.com/professional-liability-insurance/errors-omissions-insurance/technology "Technology Errors and Omissions Insurance") [14](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") [15](https://www.chubb.com/us/asset/smallbusiness/digitech-erm--new-business-application-small-business-pf-48204.pdf "Chubb DigiTech Enterprise Risk Management Policy — Technology E&O, Cyber and Privacy Short Form Application") [16](https://www.travelers.com/business-insurance/cyber-insurance/technology "Cyber Risk for Technology Companies")

## Key Differences in Tech E&O Insurance

### Marsh focuses on data-center scale and concentration

Marsh says off-the-shelf Tech E&O policies were not built for the scale and concentration of modern data centers and can leave gaps; its data-center programs combine Tech E&O with property, casualty, and other lines. Liberty Mutual describes Liberty Tech Resolution as a blended cyber and Tech E&O solution but does not address data-center scale in the reviewed claim. A data-center operator should ask Marsh which gaps its combined program addresses and ask Liberty Mutual how its form handles concentrated exposures. [8](https://www.marsh.com/en/industries/technology/expertise/data-center-insurance-and-risk-management-services.html "Data center insurance and risk management") [3](https://business.libertymutual.com/commercial-solutions/cyber-insurance/ "Cyber Insurance")

### The described program structures differ

Marsh treats Tech E&O as one part of a broader data-center insurance program and also identifies it as a financial and professional liability specialty. Liberty Mutual describes a cyber and Tech E&O product but does not mention property or casualty coverage in the reviewed claim. If you want to coordinate several lines for one facility, ask each provider which policies and limits are coordinated. [8](https://www.marsh.com/en/industries/technology/expertise/data-center-insurance-and-risk-management-services.html "Data center insurance and risk management") [3](https://business.libertymutual.com/commercial-solutions/cyber-insurance/ "Cyber Insurance")

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

- Ask Marsh which property, casualty, and Tech E&O limits are coordinated for your facility and what gaps it identified. [8](https://www.marsh.com/en/industries/technology/expertise/data-center-insurance-and-risk-management-services.html "Data center insurance and risk management")
- Ask Liberty Mutual whether its Tech E&O form addresses data-center concentration, outages, and customer service agreements. [3](https://business.libertymutual.com/commercial-solutions/cyber-insurance/ "Cyber Insurance")
