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 ↗

Coalition

  • role: Coalition designs and distributes Tech E&O as a coverage that combines with its own cyber policy, sold through appointed brokers rather than direct to buyers. Tech E&O product page as read on 2026-09-23.company-reportedSource ↗
  • eligibility: Coalition markets Tech E&O to any organization that provides a technology product or service in exchange for a fee, citing exposures such as software downtime and failures in technology services or products. Tech E&O product page as read on 2026-09-23.company-reportedSource ↗
  • coverage: Coalition says Tech E&O covers third-party financial losses from errors, omissions, or negligence in technology products or services, listing example causes including software bugs, delivery delays, IP claims over licensed code, IT-service implementation errors, and failure to meet contract requirements. Tech E&O product page as read on 2026-09-23; the issued policy and endorsements control actual coverage.company-reportedSource ↗
  • insurer: Coalition's disclaimer page lists Non-Admitted Cyber, Admitted Cyber, and Admitted Executive Risk sections naming specific carriers, but has no equivalent 'Admitted Tech E&O' section, indicating Tech E&O is placed on a non-admitted (surplus lines) basis with unaffiliated insurers that the disclaimer does not name. U.S. Disclaimers page as read on 2026-09-23; the buyer's declarations page names the actual issuing insurer for a given policy.not-disclosedSource ↗
  • services: Coalition says Tech E&O policyholders get access to Coalition Control at no extra cost, including attack-surface monitoring, vendor-risk monitoring, and zero-day alerts, the same platform provided to cyber policyholders. Tech E&O and Coalition Control pages as read on 2026-09-23.company-reportedSource ↗Source ↗
  • claims: Coalition says the same in-house claims team handles both Tech E&O and cyber claims in one place, which it describes as a faster, more integrated resolution process. Tech E&O product page as read on 2026-09-23; speed and efficiency descriptions are company-reported and not independently verified.company-reportedSource ↗
  • application: Coalition markets Tech E&O only combined with Active Cyber Insurance, not as a stand-alone policy, and directs interested buyers to schedule a consultation or work through an appointed broker. Tech E&O product page as read on 2026-09-23.company-reportedSource ↗

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

Standalone Tech E&O vs Only With Cyber

At-Bay lets your broker submit Tech E&O on its own, by underwriting email or its Broker Platform, with limits up to $10 million for companies up to $5 billion in revenue; automated quotes go up to $3 million for companies up to $100 million. Coalition sells Tech E&O only combined with Active Cyber Insurance, through appointed brokers. Choose At-Bay if you already have cyber elsewhere or need more than a few million in E&O; choose Coalition if you want E&O and cyber in one policy with one claims team. [5] [8]

One Claims Team vs a Cyber-Focused Claims Process

Coalition says the same in-house claims team handles Tech E&O and cyber, which helps when a software failure causes both a breach and a client loss. At-Bay’s claims page lays out a cyber incident roadmap but doesn’t describe how it handles an E&O dispute that isn’t a cyber incident. Both include security tools: At-Bay Stance (monitoring, virtual CISO, tabletop exercises, awareness training; managed detection sold separately) and Coalition Control (attack-surface and vendor-risk monitoring, zero-day alerts, at no extra cost). [5] [3] [7] [8]

Own Specialty Insurer vs Unnamed Insurers

At-Bay said in 2023 that new surplus-lines Tech E&O would be written by its own At-Bay Specialty Insurance Company, though its product page doesn’t name an insurer per quote. Coalition’s disclaimer names insurers for cyber and executive risks but not for Tech E&O, suggesting unaffiliated non-admitted insurers. Surplus-lines policies fall outside state guaranty funds, so ask each for the insurer. [2] [5] [9]

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

  • Ask Coalition whether you must buy Active Cyber to get Tech E&O, and At-Bay whether you can buy E&O without its cyber product. [8] [5]
  • Ask Coalition for its Tech E&O limits and revenue cap; At-Bay publishes $10 million and $5 billion. [5] [8]
  • Ask both which insurer is named on the binder. [2] [9]
  • Ask each how a professional-services claim that isn’t a breach is handled. [3] [8]

At-Bay sells Tech E&O on its own, with limits up to $10 million for companies up to $5 billion in revenue and automated quotes up to $3 million; Coalition sells Tech E&O only together with its Active Cyber policy, handled by one claims team. Both come with security monitoring.
