What Are the Key Differences Between At-Bay and Berkshire Hathaway Specialty Insurance Tech E&O Insurance?

Described policy terms and class targeting

At-Bay describes Tech E&O wording for breach-of-contract claims, breach of warranties, consequential damages and specified IP allegations. Berkshire Hathaway Specialty Insurance lists Technology E&O as a distinct product and identifies Technology Services E&O target classes, while the selected claim describes target classes rather than a policy term. Use At-Bay’s listed terms as questions for both markets, and confirm the actual wording and applicable class with each insurer; the source descriptions do not establish matching coverage. [5] [7]

Limits and quote route

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, while its automated broker quotes are limited to $100 million revenue and $3 million limits. BHSI’s reviewed Technology E&O claims name product classes but do not publish a line limit. If your company needs limits above the automated threshold, ask At-Bay about submission underwriting; ask BHSI for its available limit and terms. [5] [7]

What Should You Confirm in At-Bay and Berkshire Hathaway Specialty Insurance Tech E&O Insurance Quotes?

  • Ask At-Bay whether your revenue and requested limit qualify for automated or submission underwriting. [5]
  • Ask BHSI whether your services fit one of its named target classes and what limit is available. [7]
  • Compare the policy’s warranty, consequential-damages, IP and cyber wording. [5]

Areas of coverage

At-Bay

  • role: 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. 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.company-reportedSource ↗Source ↗
  • 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. 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.company-reportedSource ↗Source ↗
  • coverage: 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. Product-page coverage highlights; the issued policy and endorsements control actual terms.company-reportedSource ↗
  • coverage: 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. Product-page coverage highlights; the issued policy and endorsements control actual terms.company-reportedSource ↗
  • limits: 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. Published appetite ceilings, not guaranteed offers; underwriting and the appetite guide control individual accounts.company-reportedSource ↗
  • 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. Product-page InsurSec and footnote descriptions; MDR pricing is described as estimated and subject to change.company-reportedSource ↗
  • application: 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. Product-page submission instructions; the Broker Platform route is limited to accounts within its lower appetite ceilings.company-reportedSource ↗
  • claims: 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. 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-foundSource ↗

Berkshire Hathaway Specialty Insurance

  • coverage: BHSI’s U.S. Professional First overview names Technology E&O as a distinct product offering. Named U.S. product in dated overview; terms, form and current transaction availability are not provided by the catalogue listing.company-reportedSource ↗
  • eligibility: The Professional First overview identifies IT training, IT staffing, internet service providers, software design and development, and system integration as Technology Services E&O target customers. Target classes in the U.S. overview dated 2026-06-03-A; does not make technology consulting, telecommunications consulting or managed-service-provider risks ordinary targets.company-reportedSource ↗
  • eligibility: The same overview separates technology consulting, telecommunications consulting services and managed service providers as select customers. U.S. selection qualification applies; no general eligibility inference.company-reportedSource ↗
  • services: The Professional First overview describes an in-house claims group integrated with underwriting and streamlined claim reporting for its professional-line portfolio. Portfolio-level company-reported service, not technology-specific outcomes or an individual-policy claim promise.company-reportedSource ↗

At-Bay describes specific Tech E&O terms for breach of warranty, consequential damages and expanded IP claims; Berkshire Hathaway Specialty Insurance names Technology Services E&O target classes.
