## 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

### Blended coverage and the E&O module

Liberty Mutual lists Liberty Tech Resolution as a cyber and technology E&O product, describing a blended solution for technology-company exposures. CNA describes Technology E&O for businesses facing professional-liability exposures and contractual requirements, but its reviewed claims do not say that cyber is built into the same policy. If you need both lines, ask whether CNA proposes separate forms and compare them with Liberty Tech Resolution’s combined schedule. [4](https://www.cna.com/products/cyber "Cyber Insurance - Cyber Risk Solutions | CNA Insurance") [7](https://business.libertymutual.com/commercial-solutions/cyber-insurance/ "Cyber Insurance")

### Access and terms to confirm

Liberty Mutual directs business buyers to a broker or agent. CNA describes responsive claims support and privacy/data-protection risk-control resources, but the reviewed claims do not state an online application path. The records therefore show broker-led access for Liberty and service functions at CNA, without enough detail to infer differences in quote speed or policy terms. Ask each contact for the issuing insurer, E&O and cyber limits, and the exact form covering customer financial loss from a technology error. [4](https://www.cna.com/products/cyber "Cyber Insurance - Cyber Risk Solutions | CNA Insurance") [7](https://business.libertymutual.com/commercial-solutions/cyber-insurance/ "Cyber Insurance")

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

- Does CNA quote Tech E&O separately from cyber, and what limits apply to each policy? [4](https://www.cna.com/products/cyber "Cyber Insurance - Cyber Risk Solutions | CNA Insurance")
- Which Tech Resolution modules, exclusions and issuing entity appear in the Liberty Mutual proposal? [7](https://business.libertymutual.com/commercial-solutions/cyber-insurance/ "Cyber Insurance")
