CoverageTech Errors and Omissions Insurance
Also: Tech E&O
A professional liability policy that covers technology companies when their products or services cause a client to suffer financial loss.
Tech Errors and Omissions insurance (Tech E&O) is a form of professional liability coverage written for technology vendors. It responds to third-party claims that the vendor's software, hardware, IT services, or consulting work failed to perform as promised or caused a client to suffer financial loss. Defense costs and settlements for those claims are typically the core of the policy.
It is bought by software companies, SaaS providers, IT consultancies, managed service providers, and other technology vendors that deliver products or services to clients under contract. Many businesses require their technology vendors to carry Tech E&O at specified limits as a condition of doing business.
Tech E&O is closely related to Professional Liability insurance, which is the broader category covering the same family of risks for service-based professions. Tech E&O is essentially Professional Liability with wording tuned to technology delivery and often combined with a Cyber Liability section in a single form (often marketed as a tech package or hybrid policy).
The form was not built for generative AI third-party harm. Tech E&O covers the vendor that sold a software product, not the enterprise that deploys it. Bodily injury and property damage from AI outputs are typically outside the form. Intellectual property infringement is rarely covered. Financial-damage claims from a generative AI output can be disputed without affirmative AI wording. That gap is what newer Generative AI Liability forms are written to close.
For a business that deploys generative AI rather than sells it, the practical consequence is a coverage gap. Tech E&O answers the vendor's work product, Cyber Liability answers data-security events, and neither is written for third-party harm caused by an AI output in the deployer's own operations. The Verisk ISO general-liability endorsements CG 40 47 and CG 40 48 (with the products and completed operations form CG 35 08) make that exclusion explicit on the underlying Commercial General Liability form at 2026 renewals, and a growing number of Tech E&O carriers are adding parallel AI carve-outs at renewal. Affirmative generative AI liability insurance is the form built to close the gap: written to the deployer, on a claims-made basis, so the timing of placement and renewal sets what is recoverable.

Frequently asked
Does Tech E&O cover AI hallucinations?
No. Standard Tech E&O policies do not respond to third-party harm from generative AI outputs because the harm is not a covered service or product. Verisk's January 1, 2026 endorsements (CG 40 47 and CG 40 48) make the exclusion explicit on the underlying Commercial General Liability form, and a growing number of Tech E&O carriers are adding parallel AI exclusions or sub-limited carve-outs at renewal. A standalone Generative AI Liability policy is the affirmative answer.
Does Tech E&O cover generative AI output?
Not reliably. Tech E&O covers the technology vendor's product or service, not third-party harm from a generative AI output in a deployer's operations. Bodily injury and property damage from AI outputs are typically excluded, intellectual property infringement is rarely covered, and financial-damage claims can be disputed without affirmative AI wording. The Verisk ISO endorsements CG 40 47, CG 40 48, and CG 35 08 make the general-liability exclusion explicit at 2026 renewals, and a growing number of Tech E&O carriers are adding parallel carve-outs at renewal.
Tech E&O vs Cyber: which one covers AI exposure?
Neither was built for it. Cyber Liability answers data breaches, network security failures, and privacy events. Tech E&O answers the vendor's software errors and professional services. Third-party harm from a generative AI output, such as defamation, IP infringement, or a hallucinated answer that causes financial loss, falls between the two. A standalone generative AI liability policy is the affirmative cover for that exposure.
What is a typical Tech E&O limit?
Limits range from $1 million to $25 million per claim and in the aggregate. Software companies under $50 million in revenue typically buy $1 million to $5 million; companies past Series B with enterprise contracts buy $10 million to $25 million. Generative AI deployers often need higher limits because a single hallucination claim can compound across many customers who relied on the same output.
Is Tech E&O the same as Professional Liability?
They are the same family of coverage with different wording conventions. Professional Liability is the broad class for service-based professions (lawyers, accountants, consultants). Tech E&O is the technology-tuned variant for software vendors and IT service providers. Many carriers combine Tech E&O with a Cyber Liability section in a single package form, while older Professional Liability wordings often sit standalone.
