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 ↗

HUB International

  • role: HUB brokers technology E&O as part of its general E&O practice, naming technology as one of the industries it serves, and separately markets it as one line within its dedicated technology-industry practice. E&O product page and technology-industry page as read 2026-09-23; neither names an issuing insurer.company-reportedSource ↗Source ↗
  • eligibility: HUB's technology-industry page addresses fast-growing startups and established software, hardware or digital-media businesses, and says HUB currently insures more than 5,000 technology companies; that count is a company-reported figure not independently verified here. Technology-industry page framing; not specific to technology E&O alone, since the page covers HUB's full technology insurance program.company-reportedSource ↗
  • coverage: HUB's general E&O page says policies typically cover defense costs, judgments, settlements and fines from allegations of misrepresentation, breach of professional services, wrongful practices and misleading advice, and can be structured with prior-acts coverage back to a retroactive date and tail coverage for an extended reporting period. General E&O coverage description; the page does not give technology-specific coverage examples beyond listing technology as a served industry.company-reportedSource ↗
  • limits: HUB's E&O page says policies typically include per-claim and aggregate limits, but does not publish specific limit amounts for technology E&O. E&O product-page structure description; specific limits are set on the quote and declarations.not-disclosedSource ↗
  • insurer: Neither the E&O page nor the technology-industry page names an issuing insurer for technology E&O; HUB places this coverage with insurers that vary by client and placement. Checked both pages on 2026-09-23; no carrier is disclosed on either.not-foundSource ↗Source ↗
  • application: HUB directs prospects to connect with a broker; the E&O page describes policies as customized to business size, industry, location, risk base and desired limits, without an online quote flow. Product-page call to action as read 2026-09-23.company-reportedSource ↗

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

A Defined Product With Published Appetite vs a Broker That Shops the Market

At-Bay sells a defined Tech E&O policy, with Stance included on every policy, and publishes primary and excess limits up to $10 million for companies with revenue up to $5 billion; its Broker Platform gives automated quotes up to $3 million for companies up to $100 million in revenue, or you can submit by email. HUB doesn’t underwrite; its E&O and technology practices place cover with insurers that vary by placement, and it says it insures more than 5,000 technology companies, from startups to established software, hardware and digital-media firms. Choose At-Bay if you’re under $100 million in revenue and want a fast quote; choose HUB if you want a broker to shop several insurers. [5] [4] [8] [9]

Contract and Service-Credit Cover vs Prior Acts and Tail

At-Bay covers negligence and contractual indemnity, treats service credits you owe clients as damages, and offers expanded contract and IP terms. HUB says E&O typically covers defense, judgments, settlements and fines, and can include prior-acts cover back to a retroactive date plus tail coverage, which matter when you switch insurers or wind down. At-Bay doesn’t describe prior-acts or tail options. [5] [8]
