Areas of coverage

AIG

  • role: AIG markets Technology Services E&O as coverage for technology service providers. AIG is the marketing name; its legal footer says products are written or provided by subsidiaries or affiliates and does not identify the issuer for an individual policy. AIG’s U.S. Professional Liability page’s distinct Technology Services description. This is not a named policy form or issuer assignment.company-reportedSource ↗
  • eligibility: AIG identifies technology service providers as the target audience for this offering. It does not publish a complete eligible-occupation list or state-by-state appetite on the reviewed page. Target audience stated in AIG’s Technology Services section; applicant eligibility remains underwriting-specific.company-reportedSource ↗
  • coverage: AIG describes coverage for claims alleging errors or omissions in the performance of technology services, including third-party economic-loss allegations. The marketing description does not establish that a specific claim is covered; policy definitions, exclusions and conditions control. AIG’s marketing description of Technology Services E&O; no policy form or endorsement was reviewed.company-reportedSource ↗
  • services: AIG says its professional-liability claims team includes in-house professionals and third-party experts, collaborates with clients during claims, and uses claims data to help evaluate and mitigate loss. These are general company-reported professional-liability services, not a guaranteed outcome for a technology E&O claim. AIG Professional Liability page claims description; technology-specific service standards are not stated.company-reportedSource ↗
  • limits: The reviewed page does not state standard limits, retentions or deductibles for Technology Services E&O. Confirm them in the quote and issued policy. AIG’s U.S. Professional Liability page reviewed 2026-09-30; no buyer-specific quote or policy was reviewed.not-disclosedSource ↗

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 ↗

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

Contract and intellectual-property wording

At-Bay says its Tech E&O expands breach-of-contract coverage, has no exclusion for breach of warranties, guarantees, or consequential damages, and extends IP coverage to trade-secret misappropriation and several code-related disputes. AIG describes protection for allegations of errors or omissions in technology-service performance, including customer economic loss, but its reviewed public description does not enumerate these contract and IP terms. A technology company with customer warranties or proprietary code should compare the actual exclusions and endorsements directly. [6] [2]

Limits and distribution

At-Bay says it writes primary and excess Tech E&O up to $10 million for businesses with revenue up to $5 billion; broker-platform automated quotes are narrower, up to $100 million revenue and $3 million limits. AIG's page names technology service providers but does not publish limits or revenue thresholds. The buyer should distinguish At-Bay's broad stated underwriting appetite from the limits of its automated channel. [6] [2]

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

  • Ask At-Bay whether the submission is eligible for automated quoting and whether its contract/IP provisions apply to your specific claims. [6]
  • Ask AIG for available limits, retentions, and form language on warranties and IP claims. [2]

At-Bay lists specific contract and intellectual-property terms; AIG describes E&O for errors in technology-service performance without a public form-level list.
