## 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

### Cowbell publishes limits and an excess option

Cowbell says Prime Tech offers up to $5 million and Prime Tech Plus can add another layer of up to $5 million above a primary Tech E&O/cyber policy. Liberty Mutual describes a blended cyber and Tech E&O product but publishes no corresponding limit in the reviewed claim. If you need more than a primary layer, ask Cowbell about attachment terms and ask Liberty Mutual what limits it can quote. [2](https://cowbell.insure/wp-content/uploads/pdfs/CB-US-PrimeTech-Overview-1.pdf "Prime Tech Product Overview") [7](https://business.libertymutual.com/commercial-solutions/cyber-insurance/ "Cyber Insurance")

### Prime Tech names contract and cyber exposures

Cowbell lists delivery delays, negligence, misrepresentation, warranty or contract breach, product failures, software copyright disputes, and cyber costs such as extortion and data restoration. It also describes duty to defend and broad contract and IP terms. Liberty Mutual describes a blended Tech E&O and cyber solution without naming these features in the reviewed claim. Compare both wordings against your client contracts and software risks. [2](https://cowbell.insure/wp-content/uploads/pdfs/CB-US-PrimeTech-Overview-1.pdf "Prime Tech Product Overview") [7](https://business.libertymutual.com/commercial-solutions/cyber-insurance/ "Cyber Insurance")

### The target and sales channel are specific at Cowbell

Cowbell targets technology businesses up to $1 billion in revenue, including SaaS, IT consulting, analytics, and hardware resellers, and sells through agents on a surplus-lines basis. Liberty Mutual directs buyers to a broker or agent without the same stated revenue range. Ask your broker whether your revenue, state, and technology segment fit each product. [2](https://cowbell.insure/wp-content/uploads/pdfs/CB-US-PrimeTech-Overview-1.pdf "Prime Tech Product Overview") [7](https://business.libertymutual.com/commercial-solutions/cyber-insurance/ "Cyber Insurance")

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

- Ask Cowbell which state and issuing entity apply, and how the $5 million excess attaches above your existing coverage. [4](https://cowbell.insure/wp-content/uploads/pdfs/CB-PrimeTechPlusOverview.pdf "Prime Tech Plus Product Overview")
- Ask Liberty Mutual for primary and excess limits, defense treatment, and the technology classes it will consider. [7](https://business.libertymutual.com/commercial-solutions/cyber-insurance/ "Cyber Insurance")
