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

Known Policy Terms vs a Broker's Combined Placement

At-Bay describes its own Tech E&O policy, covering negligence and contractual indemnity with broader contract and IP terms, for companies with up to $5 billion in revenue and limits up to $10 million. Gallagher's Technology practice places one policy combining professional-services E&O with cyber liability for breaches, ransomware and privacy violations, using outside insurers it doesn't name, and publishes no limits. Choose At-Bay if you want to see the terms and limit ceiling before you apply; choose Gallagher if you're a larger or global tech company that wants E&O and cyber placed together by a broker.

Security Services vs Broker Scale

Every At-Bay Tech E&O policy includes Stance security services. Gallagher says its Technology practice has more than 250 dedicated staff, more than 7,500 tech and telecom clients and over $1 billion in annual premium placed, and offers client tools such as Gallagher Drive, Go, STEP, Submit and Verify. At-Bay's services help prevent a breach; Gallagher's tools help you manage the insurance program. [5] [7]

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

  • Ask Gallagher which insurer it's proposing, and ask At-Bay which company issues your policy. [7] [5]
  • Ask whether Gallagher's quote is a combined E&O and cyber form, and whether At-Bay's covers E&O only. [7] [5]
  • Compare limits, retentions and contract and IP wording on both specimens. [7] [5]

At-Bay gives you a known Tech E&O policy with limits up to $10 million for companies with up to $5 billion in revenue, plus built-in Stance security services; Gallagher is a broker that combines E&O and cyber with outside insurers for tech companies of any size. Gallagher says it serves more than 7,500 tech and telecom clients.

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 ↗

Gallagher

  • role: Gallagher's Technology insurance practice places technology E&O coverage with outside carriers for tech-sector clients; it does not underwrite the policy. Group-level technology industry practice page.company-reportedSource ↗
