# At-Bay vs Cowbell Tech E&O Insurance

At-Bay writes Tech E&O with Stance and $10 million published limits; Cowbell’s Prime Tech pairs Tech E&O with cyber up to $5 million.

## Research Scope and Use

Use this comparison to evaluate At-Bay and Cowbell 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 Stance included and limits up to $10 million. Cowbell markets Prime Tech as a non-admitted professional-indemnity form that combines Tech E&O with cyber, with limits up to $5 million and Prime Tech Plus as excess. [3](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights") [8](https://cowbell.insure/wp-content/uploads/pdfs/CB-US-PrimeTech-Overview-1.pdf "Prime Tech Product Overview") [10](https://cowbell.insure/wp-content/uploads/pdfs/CB-PrimeTechPlusOverview.pdf "Prime Tech Plus Product Overview")

## 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

### Combined Cyber Form Versus a Tech E&O Line

Cowbell markets Prime Tech as a non-admitted professional-indemnity product that combines Technology E&O with cyber in one policy, plus Prime Tech Plus as follow-form excess. At-Bay presents Tech E&O as its technology-liability line, with Stance using the same InsurSec package structure marketed with its cyber product rather than merging the two covers into one named form. Confirm whether you are being quoted a blended policy or a Tech E&O placement. [8](https://cowbell.insure/wp-content/uploads/pdfs/CB-US-PrimeTech-Overview-1.pdf "Prime Tech Product Overview") [3](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights")

### Shared Contract Language, Different Capitals

At-Bay and Cowbell both describe expansive breach-of-contract wording and say they do not exclude guarantees, consequential damages or breach of warranties. Both also describe broad intellectual-property infringement coverage. [3](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights") [8](https://cowbell.insure/wp-content/uploads/pdfs/CB-US-PrimeTech-Overview-1.pdf "Prime Tech Product Overview")

At-Bay counts service credits as payable damages and publishes $10 million limits for revenue up to $5 billion. Cowbell publishes Prime Tech limits up to $5 million, plus another $5 million of Prime Tech Plus excess, for technology businesses with up to $1 billion in revenue. [3](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights") [8](https://cowbell.insure/wp-content/uploads/pdfs/CB-US-PrimeTech-Overview-1.pdf "Prime Tech Product Overview") [10](https://cowbell.insure/wp-content/uploads/pdfs/CB-PrimeTechPlusOverview.pdf "Prime Tech Plus Product Overview")

Cowbell’s reviewed Prime Tech materials do not name the issuing insurer. At-Bay’s reviewed Tech E&O materials also do not name one per quote. [8](https://cowbell.insure/wp-content/uploads/pdfs/CB-US-PrimeTech-Overview-1.pdf "Prime Tech Product Overview") [3](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights")

### Distribution and Policyholder Tools

Cowbell says Prime Tech is surplus-lines in all 50 states and sold through agents. At-Bay takes submissions by email or through its Broker Platform, where automated quotes stop at $100 million in revenue and $3 million in limits. [8](https://cowbell.insure/wp-content/uploads/pdfs/CB-US-PrimeTech-Overview-1.pdf "Prime Tech Product Overview") [3](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights")

Cowbell attaches Co-Pilot underwriting support plus Resiliency Services, Connectors and complimentary Wizer training. At-Bay includes Stance with Tech E&O and sells managed detection and response separately through At-Bay Security, LLC. [8](https://cowbell.insure/wp-content/uploads/pdfs/CB-US-PrimeTech-Overview-1.pdf "Prime Tech Product Overview") [3](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights")

## What to Confirm in Tech E&O Insurance Quotes
- Whether Cowbell is quoting Prime Tech, Prime Tech Plus, or both, and whether At-Bay is quoting primary, excess or both. [10](https://cowbell.insure/wp-content/uploads/pdfs/CB-PrimeTechPlusOverview.pdf "Prime Tech Plus Product Overview") [3](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights")
- Limit, retention and revenue eligibility against the published $5 million / $1 billion (Cowbell) and $10 million / $5 billion (At-Bay) ceilings. [8](https://cowbell.insure/wp-content/uploads/pdfs/CB-US-PrimeTech-Overview-1.pdf "Prime Tech Product Overview") [3](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights")
- The issuing insurer on each binder. [8](https://cowbell.insure/wp-content/uploads/pdfs/CB-US-PrimeTech-Overview-1.pdf "Prime Tech Product Overview") [3](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights")
- Which security or resiliency services are included versus sold separately. [8](https://cowbell.insure/wp-content/uploads/pdfs/CB-US-PrimeTech-Overview-1.pdf "Prime Tech Product Overview") [3](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights")

## Offering Details

| Criteria | At-Bay Tech E&O Insurance | Cowbell Prime Tech / Prime Tech Plus |
| --- | --- | --- |
| 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..) | Cowbell markets Prime Tech as a non-admitted professional-indemnity product that combines Technology Errors & Omissions (E&O) with cyber coverage in one policy, and Prime Tech Plus as a follow-form excess layer that sits above a primary Tech E&O/cyber policy. [8](https://cowbell.insure/wp-content/uploads/pdfs/CB-US-PrimeTech-Overview-1.pdf "Prime Tech Product Overview") [10](https://cowbell.insure/wp-content/uploads/pdfs/CB-PrimeTechPlusOverview.pdf "Prime Tech Plus Product Overview") (Evidence: Company-reported; scope: Prime Tech and Prime Tech Plus overview PDFs..) |
| 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..) | Neither reviewed PDF names the specific issuing insurer for Prime Tech or Prime Tech Plus; both state coverage, terms and availability vary by state and are subject to underwriting approval without naming a carrier. [8](https://cowbell.insure/wp-content/uploads/pdfs/CB-US-PrimeTech-Overview-1.pdf "Prime Tech Product Overview") [10](https://cowbell.insure/wp-content/uploads/pdfs/CB-PrimeTechPlusOverview.pdf "Prime Tech Plus Product Overview") (Evidence: Not publicly disclosed; scope: Disclaimer paragraphs of both PDFs, read on 2026-09-23..) |
| Who It’s For | Not described in the reviewed sources. | Cowbell targets Prime Tech and Prime Tech Plus at technology businesses with up to $1B in revenue, listing example segments such as SaaS/app service providers, IT consultants, data analytics, hardware resellers, and web design or web services firms. [8](https://cowbell.insure/wp-content/uploads/pdfs/CB-US-PrimeTech-Overview-1.pdf "Prime Tech Product Overview") [10](https://cowbell.insure/wp-content/uploads/pdfs/CB-PrimeTechPlusOverview.pdf "Prime Tech Plus Product Overview") (Evidence: Company-reported; scope: Risk Appetite sections of both PDFs..) |
| 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..) | Cowbell lists Prime Tech coverage for delay in delivery, negligence, misrepresentation, breach of warranty/contract, product failures, and software copyright disputes, plus associated cyber-related costs like cyber extortion, data restoration, social engineering, and business interruption. [8](https://cowbell.insure/wp-content/uploads/pdfs/CB-US-PrimeTech-Overview-1.pdf "Prime Tech Product Overview") (Evidence: Company-reported; scope: Prime Tech FAQ, 'What coverage is offered?' and 'other associated costs' lists..)<br><br>Cowbell says Prime Tech includes duty to defend, defense costs for privacy-related regulatory proceedings, contractual-indemnity coverage, expansive breach-of-contract coverage, broad intellectual-property infringement coverage, and no exclusions for guarantees, consequential damages, or breach of warranties. [8](https://cowbell.insure/wp-content/uploads/pdfs/CB-US-PrimeTech-Overview-1.pdf "Prime Tech Product Overview") (Evidence: Company-reported; scope: 'Prime Tech Coverage Benefits' list; illustrative, subject to the issued policy..) |
| 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..) | Cowbell states Prime Tech offers limits up to $5M, and Prime Tech Plus (the excess layer) also offers limits up to $5M above the underlying primary policy. [8](https://cowbell.insure/wp-content/uploads/pdfs/CB-US-PrimeTech-Overview-1.pdf "Prime Tech Product Overview") [10](https://cowbell.insure/wp-content/uploads/pdfs/CB-PrimeTechPlusOverview.pdf "Prime Tech Plus Product Overview") (Evidence: Company-reported; scope: Product overview PDFs..) |
| 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..) | Cowbell says Prime Tech is 'powered by Cowbell Co-Pilot,' its AI-driven assistive underwriting tool, and that policyholders get the same Cowbell Resiliency Services, Cowbell Connectors, and complimentary Wizer cybersecurity-awareness training offered on its cyber products. [8](https://cowbell.insure/wp-content/uploads/pdfs/CB-US-PrimeTech-Overview-1.pdf "Prime Tech Product Overview") (Evidence: Company-reported; scope: Prime Tech PDF, page 2 (Cowbell Co-Pilot mention) and 'The Cowbell Advantage' list..) |
| 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..) | Cowbell says Prime Tech is available on a surplus-lines basis in all 50 states and is distributed through agents rather than direct to businesses. [8](https://cowbell.insure/wp-content/uploads/pdfs/CB-US-PrimeTech-Overview-1.pdf "Prime Tech Product Overview") (Evidence: Company-reported; scope: 'Prime Tech Coverage Benefits' list, first bullet..) |
| 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. |
