## 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")

## Key Differences in Tech E&O Insurance

### At-Bay states a maximum limit and revenue range

At-Bay says it writes primary and excess Tech E&O for businesses with revenue up to $5 billion and limits up to $10 million. Its broker platform automates quotes only up to $100 million in revenue and $3 million in limits. Liberty Mutual describes a blended cyber and Tech E&O product but gives no comparable limits in the reviewed claim. If you exceed the automated thresholds, ask At-Bay for a manual submission and request Liberty Mutual's available limits through a broker. [3](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights") [9](https://business.libertymutual.com/commercial-solutions/cyber-insurance/ "Cyber Insurance")

### At-Bay names specific professional-liability terms

At-Bay describes coverage for coding errors, failed implementations, network outages, contractual indemnity, and service credits as damages, plus IP infringement including trade-secret misappropriation. Liberty Mutual describes a combined cyber and Tech E&O solution for technology exposures without these wording details in the reviewed claim. Compare the policy language for your contracts and software risks instead of relying on the product label. [3](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights") [9](https://business.libertymutual.com/commercial-solutions/cyber-insurance/ "Cyber Insurance")

### Both are broker-accessed, with different submission routes

At-Bay accepts emailed underwriting submissions or automated quotes through its Broker Platform. Liberty Mutual directs buyers to a broker or agent. Ask your broker which route applies at At-Bay and what submission process Liberty Tech Resolution requires. [3](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights") [9](https://business.libertymutual.com/commercial-solutions/cyber-insurance/ "Cyber Insurance")

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

- Ask At-Bay which issuing entity, limit, and Stance services apply to your quote, and whether your revenue exceeds the automated threshold. [3](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights")
- Ask Liberty Mutual for the Tech E&O form, cyber limit, and treatment of service credits and contractual indemnity. [9](https://business.libertymutual.com/commercial-solutions/cyber-insurance/ "Cyber Insurance")

## Offering Details

| Criteria | At-Bay Tech E&O Insurance | Liberty Tech Resolution |
| --- | --- | --- |
| Role in This Line | At-Bay places Tech E&O insurance through its disclosed producer, At-Bay Insurance Services LLC, which is licensed as an insurance producer in all 50 states. At-Bay says eligible new excess-and-surplus (E&S) Tech E&O business has been written on its own carrier paper, At-Bay Specialty Insurance Company, since August 2023. [4](https://www.at-bay.com/licenses/ "Licenses") [5](https://www.at-bay.com/press_releases/at-bay-begins-issuing-policies-on-its-own-paper/ "At-Bay Begins Issuing Policies on its own E&S Paper") (Evidence: Company-reported; scope: Producer role from the current license page; carrier role from a 2023 transition announcement covering Cyber and Tech E&O together, not confirmed for every current quote..) | Liberty Mutual lists Liberty Tech Resolution as a cyber and technology errors-and-omissions product.

| Issuing Insurer | The current Tech E&O product page does not name an issuing insurer. At-Bay's 2023 announcement says new E&S Tech E&O business is quoted on At-Bay Specialty Insurance Company paper, but that is a historical statement, not a per-quote disclosure. [3](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights") [5](https://www.at-bay.com/press_releases/at-bay-begins-issuing-policies-on-its-own-paper/ "At-Bay Begins Issuing Policies on its own E&S Paper") (Evidence: Company-reported; scope: Tech E&O product page checked today names no insurer; the carrier-transition release is dated August 2023 and does not cover every current state or account..) | Confirm in your quote. |

Not policy wording, underwriting approval, state eligibility or a coverage guarantee..) |
| Coverage Features | At-Bay says its Tech E&O policy expands breach-of-contract coverage beyond a standard technology liability policy, carries no exclusion for breach of warranties, guarantees or consequential damages, and extends intellectual-property infringement coverage to trade-secret misappropriation, cybersquatting, improper deep-linking and source-code license violations, in addition to standard software copyright infringement. [3](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights") (Evidence: Company-reported; scope: Product-page coverage highlights; the issued policy and endorsements control actual terms..)<br><br>At-Bay describes negligence coverage for improper installations, coding errors, data-processing flaws, failed implementations and network outages, plus contractual-indemnity coverage for obligations a technology company owes customers from an alleged wrongful act. It also counts service credits issued to settle a claim as payable damages under the policy. [3](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights") (Evidence: Company-reported; scope: Product-page coverage highlights; the issued policy and endorsements control actual terms..) | The company describes a blended cyber and Tech E&O solution for technology-company exposures. [9](https://business.libertymutual.com/commercial-solutions/cyber-insurance/ "Cyber Insurance") (Evidence: Company-reported; scope: Official Liberty Mutual commercial/product page; company-reported description scoped to Liberty Tech Resolution. Not policy wording, underwriting approval, state eligibility or a coverage guarantee..) |
| Limits and Retentions | At-Bay says it writes primary and excess Tech E&O insurance for businesses with revenue up to $5 billion and limits up to $10 million. Through its Broker Platform, brokers can get automated quotes only for businesses up to $100 million in revenue and $3 million in limits. [3](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights") (Evidence: Company-reported; scope: Published appetite ceilings, not guaranteed offers; underwriting and the appetite guide control individual accounts..) | Confirm in your quote. |
| Risk Services | Every At-Bay Tech E&O policy includes access to At-Bay Stance, a security platform with vulnerability monitoring, vCISO advisory and tabletop exercises, and security awareness training, the same InsurSec package structure marketed with its cyber product. Managed detection and response (MDR) is a separate purchase sold by At-Bay Security, LLC. [3](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights") (Evidence: Company-reported; scope: Product-page InsurSec and footnote descriptions; MDR pricing is described as estimated and subject to change..) | Confirm in your quote. |
| How to Apply | You apply for At-Bay Tech E&O coverage by emailing a submission to underwriting@at-bay.com or by requesting an automated quote through At-Bay's Broker Platform. [3](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights") (Evidence: Company-reported; scope: Product-page submission instructions; the Broker Platform route is limited to accounts within its lower appetite ceilings..) | The cited product page does not establish an online application or policy-binding path; ask the listed team or your broker/agent how this product is placed. [9](https://business.libertymutual.com/commercial-solutions/cyber-insurance/ "Cyber Insurance") (Evidence: Not found in reviewed sources; scope: Reviewed product-page scope only. This not-found disposition is not a claim that no digital route exists..) |
| Claims Support | At-Bay's claims-handling page describes a cyber incident roadmap and breach-coach hotline for ransomware and system-interruption events, but the reviewed page does not describe a separate process for a Tech E&O claim that does not involve a cyber incident, such as a professional-liability or contract dispute. [6](https://www.at-bay.com/claims/ "Claims Handling") (Evidence: Not found in reviewed sources; scope: Claims-handling page as read on 2026-09-23; does not establish that no Tech E&O-specific process exists, only that this page does not describe one..) | Confirm in your quote. |
