Technology errors and omissions (tech E&O) insurance is professional liability coverage for technology businesses facing third-party claims that an error, omission, negligent service, or product failure caused financial loss. Depending on the policy, it may cover defense costs and damages, subject to the contract’s limits, exclusions, endorsements, and claim-reporting rules.
What technology E&O insurance means
Tech E&O focuses on alleged financial harm to a customer or another third party arising from a technology product or service. AIG Canada describes it as coverage against a claim that the insured was negligent in providing a technology service. The allegation does not establish that the business actually made a mistake, and an allegation alone does not guarantee coverage; the policy wording and facts determine whether the insurer responds.

The covered work is defined by the policy. AIG Canada lists examples such as systems analysis and integration, software development, data processing, technology consulting, support, maintenance, and work involving technology products. A company should check that its real services and products fit the policy’s definition, rather than relying on the label “tech E&O.”

These scenarios illustrate the kinds of allegations insurers describe; they are not promises that a particular policy will cover a claim.
- An e-commerce platform crashes, and customers allege resulting financial losses.
- A technology consultant faces a claim that incorrect advice about configuring a client’s software platforms caused loss.
- A software glitch interrupts a client’s network, leading a third party to seek compensation.
- A CRM malfunction prevents a company from accessing customer contacts and contributes to lost revenue.
Which businesses may consider tech E&O
Businesses that develop, integrate, process, support, license, distribute, or manufacture technology may have exposures the coverage is designed to address. Examples include software and systems developers, IT service providers, technology consultants, systems integrators, data-processing firms, and hardware or electronics manufacturers. AIG Canada and Chubb describe these kinds of technology businesses in their product materials.
Whether a particular business should buy coverage depends on its work, customer contracts, risk profile, location, available policy wording, limits, and exclusions. The cited sources do not establish a universal legal requirement for tech E&O. Requirements can depend on the jurisdiction and profession; clients may also ask a vendor to show proof of professional liability insurance.
Tech E&O vs. cyber insurance vs. general liability
The product names are not enough to determine which claims are covered. Compare the actual insuring agreements: cyber and E&O protections can overlap or appear in one bundled product, while general liability addresses a different common set of claims.
| Coverage | Main exposure described by the cited sources | What to check |
|---|---|---|
| Technology E&O | Third-party financial loss allegedly caused by an error, omission, negligence, or failure in a technology product or service. AIG Canada | Whether the policy’s definition of technology or professional services includes the work at issue, and how its claim terms apply. |
| Cyber insurance | Data, network security, breach response, recovery, and related cyber exposures. Some policies include both first-party and third-party coverage. Progressive Commercial; Chubb | Which cyber modules are included and whether they cover the business’s own losses, claims by others, or both. |
| General liability | Commonly bodily injury and property damage claims, distinct from professional liability. Texas Department of Insurance | Whether the business also needs this separate coverage for risks outside professional services. |
Progressive’s shorthand is that tech E&O addresses financial loss from a failed product or service, while cyber insurance addresses data loss and attacks. That distinction is useful but not a complete comparison of any two policies. Chubb’s DigiTech ERM is one example of a product combining technology E&O, media, and cyber exposures; it does not establish a standard bundle across insurers.
Policy details to check before relying on coverage
- Covered services and products: Look for the actual work the business performs, such as SaaS, software development, systems integration, hosting, consulting, data processing, implementation, or support. Ask about any services or products that are absent or described too narrowly.
- Defense costs and limits: Confirm whether defense costs reduce the limit or are payable outside it, along with per-claim and aggregate limits, deductibles or retentions, and sublimits. AIG describes defense costs and damages within the liability limit for its cited Tech E&O offering; policy arrangements can differ.
- Claim reporting: Many professional liability policies are claims-made. Texas Department of Insurance explains that this generally means the incident and claim report must fall within the defined coverage periods, unless special coverage is arranged. Check the policy’s reporting window, retroactive date, continuity terms, and any extended reporting provision.
- Exclusions and endorsements: There is no single exclusions list that can be assumed to apply to every tech E&O policy. Read the actual contract and endorsements, since coverage depends on their terms and the claim’s facts.
- Cyber modules: Determine whether the policy includes network security, privacy, incident response, business interruption, data recovery, cyber extortion, or media coverage, and whether each is a first-party or third-party grant.
- Contracts and territory: Compare policy limits and proof-of-insurance requirements with customer contracts. Verify the policy’s territorial scope and availability where the business operates.
Why claim timing matters
For claims-made coverage, the date a problem occurred may not be the only relevant date: the claim and its report must meet the policy’s timing conditions. Occurrence coverage instead generally turns on when the incident happened. Texas Department of Insurance describes these broad distinctions, but the policy controls the applicable terms, including any reporting window or extended reporting arrangement.

The definition and technology-service examples above reflect AIG Canada’s Tech E&O description. The distinction between tech E&O and cyber and the bundled-product example draw on Progressive Commercial and Chubb. General professional-liability and claim-timing context comes from the Texas Department of Insurance. AIG’s U.S. coverage information likewise emphasizes that coverage depends on policy terms, conditions, exclusions, and the claim’s facts: AIG U.S.. These descriptions explain the coverage category; they do not determine whether a particular business or claim is insured.
