## 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. [8](https://content.naic.org/glossary-insurance-terms "Glossary of Insurance Terms") [9](https://doas.ga.gov/sites/default/files/2025-08/SPD-SP048%20Insurance%20and%20Bonding%20Guidelines%20August%202025.pdf "Insurance and Bonding Guidelines") [10](https://online.ogs.ny.gov/purchase/snt/awardnotes/7360022802AppendixJ_PRB01.pdf "Appendix J – Contractor’s Insurance Requirements, Information Technology Umbrella Contract – Manufacturer Based (Statewide)") [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") [13](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") [14](https://www.travelers.com/business-insurance/cyber-insurance/technology "Cyber Risk for Technology Companies")

## Key Differences in Tech E&O Insurance

### Contract requirements and technology segments

CNA says its Technology E&O is intended to support contractual requirements and describes coverage for technology businesses facing professional-liability exposures. Markel lists software and SaaS businesses, hardware companies and consultants as target audiences for its technology product. These descriptions help identify an initial fit, but Markel’s source expressly leaves actual terms, exclusions, limits and availability to the issued policy. Ask both carriers to address the technology services and contract commitments your customers require. [4](https://www.cna.com/products/cyber "Cyber Insurance - Cyber Risk Solutions | CNA Insurance") [7](https://www.markel.com/us/commercial/professional-and-management-liability/errors-and-omissions/it-professionals "IT Professionals E&O Insurance")

### Quote path and policy wording

Markel invites prospective buyers or brokers to contact its underwriting team but does not establish a quote or binding timeline. CNA describes responsive claims and privacy/data-protection risk-control resources for technology clients. The buyer should separate access from policy service: how to start underwriting is distinct from who helps after a loss. Ask Markel what application information and decision timeline apply, and ask CNA what technology risk resources are available with the proposed form. [4](https://www.cna.com/products/cyber "Cyber Insurance - Cyber Risk Solutions | CNA Insurance") [7](https://www.markel.com/us/commercial/professional-and-management-liability/errors-and-omissions/it-professionals "IT Professionals E&O Insurance")
