What Is Technology Errors and Omissions (E&O) Insurance?
Technology errors and omissions coverage can help pay when a customer claims your software, hosting, installation or technology advice caused financial loss. If you provide tech products or services, check each activity; cyber incidents and unrelated professional work need separate review. 7,8,9,10,11,12,13
Key Differences in Tech E&O Insurance
Coverage design and fit
Markel lists software and SaaS, hardware businesses, and consultants among technology-service businesses for its professional-liability product. AIG identifies technology service providers as its target and describes allegations of errors or omissions in performing those services, including economic loss. Applicants whose work spans hardware, software, and consulting should ask each underwriter to classify every revenue stream and identify applicable exclusions. 3 6
Eligibility, services, and placement
Markel invites prospective customers or brokers to contact its underwriting team but does not establish a quote or binding timeline. AIG describes a professional-liability claims team with in-house and third-party experts. Ask Markel about submission timing and ask AIG how those claim resources apply to technology accounts. 3 6
