# At-Bay vs Chubb Tech E&O Insurance

At-Bay writes Tech E&O as its own product with Stance bundled in; Chubb folds it into DigiTech ERM with media and cyber.

## Research Scope and Use

Use this comparison to evaluate At-Bay and Chubb 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 a Tech E&O policy with expanded contract and IP terms plus Stance security access. Chubb underwrites the same exposure inside DigiTech ERM, a combined tech E&O, media and cyber form. [3](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights") [9](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products")

## What Is At-Bay Insurance?

At-Bay offers Cyber, Tech E&O, and miscellaneous professional liability insurance through its disclosed insurance agency and surplus lines broker. Its Stance security services have policy eligibility conditions, with managed detection and response sold separately.

## What Is Chubb?

Chubb is the marketing name for a global insurance group whose U.S. companies underwrite commercial property, casualty, cyber and financial-lines coverage, including technology-focused DigiTech ERM and small-business packages. Founders and finance teams typically work through an appointed agent, then receive a policy issued by a named Chubb-group insurer rather than by the Swiss holding company.

## 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. [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://www.thehartford.com/professional-liability-insurance/errors-omissions-insurance/technology "Technology Errors and Omissions Insurance") [13](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

### How the Product Is Packaged

At-Bay sells Tech E&O as a technology-liability policy its producer places, while Chubb underwrites the exposure only as part of DigiTech ERM, which also folds in media and cyber rather than issuing tech E&O on its own. That packaging decision changes whether you are buying a dedicated professional-liability form or a combined enterprise-risk policy. [3](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights") [9](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products")

### Contract, IP and Product Triggers

At-Bay says its form expands breach-of-contract coverage, does not exclude warranties, guarantees or consequential damages, and extends IP infringement to trade secrets, cybersquatting, deep-linking and source-code license issues. Chubb’s DigiTech ERM add-on is described as third-party financial injury from products or services, a broadened “technology incident,” software copyright infringement and product-recall loss of use, with no exclusion for delays or failure to deliver. Ask which of those triggers actually appear on the specimen you receive. [3](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights") [9](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products")

### Limits, Paper and Ongoing Services

At-Bay publishes primary and excess capacity up to $10 million for firms with revenue up to $5 billion, and notes 2023 E&S quoting on At-Bay Specialty Insurance Company paper. Chubb’s reviewed DigiTech pages do not publish limit or retention amounts. Every At-Bay Tech E&O policy includes Stance (vulnerability monitoring, vCISO advisory, tabletops and awareness training); DigiTech ERM policyholders get Chubb’s cyber panel, 24/7 hotline and Cyber Alert app. [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") [9](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products")

## What to Confirm in Tech E&O Insurance Quotes
- Whether Chubb is quoting DigiTech ERM as a combined form and whether At-Bay is quoting Tech E&O primary, excess or both. [9](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") [3](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights")
- The issuing insurer on each quote; At-Bay’s current product page does not name one, and Chubb’s reviewed pages do not either. [3](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights") [10](https://www.chubb.com/us-en/business-insurance/software-system-developers.html "Insurance for Software Product & System Developers")
- How contract, warranty, copyright and delay language is actually worded versus the marketing highlights. [3](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights") [9](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products")
- Which security or incident-response services attach at bind, and whether Chubb’s cyber tools require the full ERM package. [3](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights") [9](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products")

| --- | --- | --- |
| 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..) | Chubb underwrites technology errors and omissions coverage through DigiTech ERM, a single policy that combines tech E&O with media and cyber exposures rather than selling tech E&O standalone.

| 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..) | Not described in the reviewed sources. |

| 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..) | Beyond the Cyber ERM base, Chubb says DigiTech ERM adds technology errors and omissions coverage for third-party financial injury from the insured's products or services, a broadened definition of "technology incident," and coverage for software copyright infringement and product-recall loss of use, with no exclusion for delays or failure to deliver. [9](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") (Evidence: Company-reported; scope: DigiTech ERM Product Features list; subject to the policy as issued..) |

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 reviewed pages do not publish specific limit or retention amounts for DigiTech ERM's technology E&O coverage. [9](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") (Evidence: Not found in reviewed sources; scope: Cyber Insurance Coverage & Products page as read on 2026-09-23..) |
| 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..) | DigiTech ERM policyholders get the same cyber services as Cyber ERM, including a panel of pre-approved incident response providers, a 24/7 hotline and Cyber Alert app. [9](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") (Evidence: Company-reported; scope: Cyber Insurance Coverage & Products page; DigiTech ERM includes "all the features of Cyber ERM.".) |
| 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..) | Agents and brokers can quote DigiTech ERM through Chubb's Cyber Central or Marketplace quoting platforms, and Chubb lists E&O/Cyber among the coverage solutions available to technology companies generally. [9](https://www.chubb.com/us-en/business-insurance/products/cyber-insurance/cyber-insurance-products.html "Cyber Insurance Coverage & Products") [7](https://www.chubb.com/us-en/business-insurance/industries/technology.html "Insurance for Technology Companies") (Evidence: Company-reported; scope: Cyber Insurance Coverage & Products quoting section; technology-industry products list..) |
| 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. |
