# At-Bay vs Gallagher Tech E&O Insurance

At-Bay places a named Tech E&O form with Stance; Gallagher’s technology practice brokers a combined E&O and cyber placement.

## Research Scope and Use

Use this comparison to evaluate At-Bay and Gallagher for Tech E&O Insurance against the same documented criteria. It identifies differences and questions to confirm; it does not select a winner for a particular business. Offering claims are what each provider publishes about this line unless marked otherwise. “Not found” describes the evidence reviewed, not proof that a feature is unavailable. Confirm the insurer, policy wording, limits, retentions, exclusions and cost in an actual quote.

## Summary

At-Bay describes its own Tech E&O policy, published limits and Stance access. Gallagher’s Technology practice places combined professional-services E&O and cyber coverage with outside carriers and does not publish limits or name the insurer.

## What Is Technology Errors and Omissions (E&O) Insurance?

Technology errors and omissions (E&O) insurance addresses claims that a technology product or service caused a customer or other third party a financial loss. It doesn't extend to cyber incidents, bodily injury or professional services outside the quoted product. [12](https://doas.ga.gov/sites/default/files/2025-08/SPD-SP048%20Insurance%20and%20Bonding%20Guidelines%20August%202025.pdf "Insurance and Bonding Guidelines") [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")

## Key Differences in Tech E&O Insurance

### Program Form Versus Brokered Placement

At-Bay places Tech E&O through its producer and describes a specific policy, including negligence, contractual indemnity and expanded contract and IP terms. Gallagher’s Technology practice places technology E&O with outside carriers and does not underwrite it; it markets the line as a single policy combining errors from rendering or failing to render professional services with cyber liability for breaches, ransomware and privacy violations. You are comparing a named At-Bay form with a Gallagher placement whose wording will follow the chosen market. [3](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights") [4](https://www.at-bay.com/licenses/ "Licenses") [7](https://www.ajg.com/industries/technology-insurance/ "Technology Insurance for the Tech Industry")

### Who the Practice Is Built For

At-Bay publishes an appetite of revenue up to $5 billion and limits up to $10 million. Gallagher says its Technology practice serves startups through global enterprises, citing more than 7,500 technology and telecommunications clients and over $1 billion in annual premium placed; those figures are company-reported. Gallagher’s reviewed technology page does not publish Tech E&O limits or name an issuing insurer. [3](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights") [7](https://www.ajg.com/industries/technology-insurance/ "Technology Insurance for the Tech Industry")

### Services Around the Policy

Every At-Bay Tech E&O policy includes Stance. Gallagher offers technology clients Gallagher Drive, Go, STEP, Submit and Verify, plus a Technology practice it says includes more than 250 dedicated professionals. Those are brokerage and client-portal tools, not the same as an insurer-attached security platform.

| Criteria | At-Bay Tech E&O Insurance | Gallagher Technology Errors and Omissions (Tech E&O) Insurance |
| --- | --- | --- |
| 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..) | Gallagher's Technology insurance practice places technology E&O coverage with outside carriers for tech-sector clients; it does not underwrite the policy.

| 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..) | The technology industry practice page does not name the insurer that would issue a given client's technology E&O policy.

[7](https://www.ajg.com/industries/technology-insurance/ "Technology Insurance for the Tech Industry") (Evidence: Company-reported; scope: Group-level technology industry practice page; company-reported client and premium figures, not independently verified..) |
| 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..) | Gallagher markets technology E&O as a single policy combining coverage for errors and omissions from rendering or failing to render professional services with cyber liability coverage for perils such as data breaches, ransomware attacks and privacy violations. [7](https://www.ajg.com/industries/technology-insurance/ "Technology Insurance for the Tech Industry") (Evidence: Company-reported; scope: Group-level technology industry practice page; a service description, not a specific policy's insuring agreement or exclusions..) |
| 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..) | The technology industry practice page does not publish limits, retentions or premium ranges for technology E&O. [7](https://www.ajg.com/industries/technology-insurance/ "Technology Insurance for the Tech Industry") (Evidence: Not publicly disclosed; scope: Checked the group-level technology industry practice page..) |
| 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..) | Gallagher offers technology clients a digital suite including Gallagher Drive for data-driven risk analytics, Gallagher Go as a client self-service portal, Gallagher STEP for online safety training, Gallagher Submit for insurance-submission tracking, and Gallagher Verify for certificate management. [7](https://www.ajg.com/industries/technology-insurance/ "Technology Insurance for the Tech Industry") (Evidence: Company-reported; scope: Group-level technology industry practice page; not confirmed as included with every tech E&O placement..)<br><br>Gallagher says its Technology insurance practice includes more than 250 dedicated professionals and points to named team leaders reachable at Rolling Meadows, Illinois phone numbers. [7](https://www.ajg.com/industries/technology-insurance/ "Technology Insurance for the Tech Industry") (Evidence: Company-reported; scope: Group-level technology industry practice page..) |
| 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..) | Not described in the reviewed sources. |
| 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..) | Not described in the reviewed sources. |
