## 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

### Technology classes and contractual purpose

Zurich identifies hardware and software product makers and technology service providers as E&O classes. CNA describes Technology E&O for technology businesses facing professional-liability exposures and says the coverage is intended to support contractual requirements. A company building a product and advising clients may fit both broad descriptions, but the relevant class and service definition in the quote matter. Ask each insurer how the proposed policy treats your products, implementation work and contractual indemnities. [4](https://www.cna.com/products/cyber "Cyber Insurance - Cyber Risk Solutions | CNA Insurance") [7](https://www.zurichna.com/insurance/errors-and-omissions "Errors and Omissions Insurance – E&O | Zurich Insurance")

### Claims support and form details

Zurich describes dedicated E&O claims specialists and underwriters, and says coverage may include defense costs, settlements and court fees; crisis management is an enhanced endorsement for qualified buyers. CNA identifies dedicated claims and risk-control support, including privacy and data-protection resources. Compare what is included with the base form versus available by endorsement. Ask both for the claims contact, defense-cost treatment and whether crisis response is included or separately endorsed. [4](https://www.cna.com/products/cyber "Cyber Insurance - Cyber Risk Solutions | CNA Insurance") [7](https://www.zurichna.com/insurance/errors-and-omissions "Errors and Omissions Insurance – E&O | Zurich Insurance")

- Which CNA wording addresses technology services, contracts and privacy events, and what limit applies? [4](https://www.cna.com/products/cyber "Cyber Insurance - Cyber Risk Solutions | CNA Insurance")
- Does Zurich’s quote include crisis management, and which claims services and defense-cost terms are in the base form? [7](https://www.zurichna.com/insurance/errors-and-omissions "Errors and Omissions Insurance – E&O | Zurich Insurance")
