## 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")

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

### Standard Technology Businesses and Data Centers

Markel lists software/SaaS, hardware businesses, and consultants in its Tech E&O audience. Marsh says technology E&O is a specialty and that off-the-shelf forms may leave gaps for data centers, so its data-center program combines Tech E&O with property, casualty, and other lines. A software vendor can ask Markel about its technology form; a data-center operator should ask Marsh how the E&O wording coordinates with property and operational exposures. [3](https://www.markel.com/us/commercial/professional-and-management-liability/errors-and-omissions/it-professionals "IT Professionals E&O Insurance") [8](https://www.marsh.com/en/industries/technology/expertise/data-center-insurance-and-risk-management-services.html "Data center insurance and risk management")

### Program Design and Industry Expertise

Marsh names Tech E&O among its professional-liability specialties for technology and other specialized industries, with a separate data-center program built around concentrated infrastructure risks. Markel's product page describes broadly defined technology services but does not detail a data-center package in its offering record. If your facility owns or operates critical infrastructure, ask Markel whether its form addresses that operating model or request Marsh's coordinated program structure. [9](https://www.marsh.com/en/services/financial-professional-liability/expertise/professional-liability.html "Professional liability") [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://www.markel.com/us/commercial/professional-and-management-liability/errors-and-omissions/it-professionals "IT Professionals E&O Insurance")

### Quote Scope

The reviewed Marsh claim describes a coordinated data-center program rather than published limits or a standard online quote path. Markel invites buyers or brokers to contact its team and likewise does not state limits in the summarized Tech E&O claims. Request the same services, revenue, property values, and limits in both submissions to compare how the program addresses technology liability and physical infrastructure together. [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://www.markel.com/us/commercial/professional-and-management-liability/errors-and-omissions/it-professionals "IT Professionals E&O Insurance")

## What Should You Confirm in Markel Insurance and Marsh Tech E&O Insurance Quotes?

- Ask Marsh which Tech E&O terms are integrated with property and casualty in the data-center program and how limits coordinate. [8](https://www.marsh.com/en/industries/technology/expertise/data-center-insurance-and-risk-management-services.html "Data center insurance and risk management")

- Ask Markel whether its Tech E&O class includes data-center operators and what property or infrastructure risks require separate policies. [3](https://www.markel.com/us/commercial/professional-and-management-liability/errors-and-omissions/it-professionals "IT Professionals E&O Insurance")
