AIG vs At-Bay: How Do They Compare for Tech E&O Insurance?

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. ³Company-reported. AIG’s U.S. Professional Liability page’s distinct Technology Services description. This is not a named policy form or issuer assignment.

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. ^7,8Company-reported. 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.

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. ^6,8Company-reported. 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.

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. ³Company-reported. Target audience stated in AIG’s Technology Services section; applicant eligibility remains underwriting-specific.

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. ⁶Company-reported. Product-page coverage highlights; the issued policy and endorsements control actual terms.

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. ⁶Company-reported.

Published appetite ceilings, not guaranteed offers; underwriting and the appetite guide control individual accounts.

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. ³Company-reported. AIG Professional Liability page claims description; technology-specific service standards are not stated.

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. ⁶Company-reported. Product-page InsurSec and footnote descriptions; MDR pricing is described as estimated and subject to change.

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. ⁹Not found in reviewed sources. 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.
