What Is Tech E&O Insurance?
Tech E&O insurance — short for technology errors and omissions, also called technology professional liability — is the coverage that pays to defend and settle claims that your technology product or service failed and caused a client a financial loss. If a customer says your software didn't perform as promised, that you were negligent, that you missed a deadline, or that you fell short of a service-level agreement, Tech E&O is the policy that funds the lawyers and any settlement or judgment. In plain terms: cyber covers what happens to data; Tech E&O covers what happens when your work product disappoints a paying client and they decide it cost them real money. This guide explains what Tech E&O actually covers, how it differs from general liability and cyber, who needs it, and what it typically costs in today's market. It is written for founders, CFOs, and general counsel deciding which policies belong in their first real insurance program.
What Tech E&O Insurance Covers
Tech E&O responds to third-party claims arising from your technology product or professional services — the work you deliver, not an injury or property damage. The trigger is usually an allegation that you were negligent, made an error or omission, failed to perform, or breached a professional duty, and that a client lost money as a result.
- Failure to perform. A client alleges your platform didn't do what your contract promised, causing quantifiable harm.
- Negligence and errors. A coding mistake, faulty integration, or missed configuration step leads to a client loss.
- Missed SLAs and downtime. Service-level commitments you fall short of, where the contract attaches financial consequences.
- Defense costs. The policy pays legal defense even when a claim is meritless — often the largest cost in these disputes.
Because the technology exposures overlap, Tech E&O is frequently sold combined with cyber liability for software companies, so one policy responds whether the problem is a service failure or a data incident. Compare the two in our cyber insurance vs data-breach insurance and tech E&O insurance guides.
How Tech E&O Differs From Cyber and General Liability
These three coverages are easy to confuse because tech companies often carry all of them. The distinction is about what kind of harm triggers the claim.
| Coverage | What triggers a claim |
|---|---|
| Tech E&O | Your product or service failed and cost a client money |
| Cyber liability | Data was breached, systems were held to ransom, or funds were stolen |
| General liability | Bodily injury or physical property damage (the slip-and-fall risks) |
General liability won't respond to a software defect, and cyber won't respond to a pure performance dispute. That is why most technology programs pair Tech E&O with cyber and a general liability base — each fills a gap the others leave open. For the broader picture, see our startup insurance overview.
Who Needs Tech E&O Insurance?
Any company whose revenue depends on delivering a technology product or professional service to clients should treat Tech E&O as core, not optional. That includes SaaS and software firms, IT consultants, managed service providers, app developers, and increasingly AI/ML companies whose models can produce inaccurate outputs.
The single biggest practical driver is contracts. Enterprise master service agreements commonly require named-insured or additional-insured status and minimum limits — often $1M–$2M of tech E&O or professional liability — before they will sign. In those cases the policy stops being a back-office line item and becomes a prerequisite to closing the deal. Many founders first buy Tech E&O the week a large customer's procurement team asks for a certificate of insurance.
What Tech E&O Insurance Typically Costs
There is no flat price; underwriters weigh your revenue, the software or service you sell, your contract terms, and your controls. Typical market ranges as of 2026 put early-stage technology programs — often cyber and tech E&O combined — in the low-to-mid four figures annually for $1M of coverage, scaling with limits and risk. Vouch's 2026 benchmarks put typical early-stage program figures around $2,900 and $3,700 annually — a directional anchor, not a quote. For more, see our cyber insurance cost guide.

Frequently asked questions
Is Tech E&O the same as professional liability insurance?
Essentially yes. Tech E&O is professional liability tailored to technology companies. Traditional professional liability (or "errors and omissions") covers professionals like accountants and architects; Tech E&O applies the same concept to software products and technology services, and is often bundled with cyber coverage.
Does Tech E&O cover a data breach?
Not by itself. A data breach, ransomware event, or stolen funds is a cyber claim. Because the exposures are related, carriers commonly write Tech E&O and cyber together on one policy for technology firms, so both kinds of claims are handled.
Why do my customers ask for Tech E&O coverage?
Enterprise buyers want assurance that if your product fails and harms their business, there is a funded policy behind any claim rather than just your balance sheet. That is why master service agreements often specify minimum tech E&O limits and additional-insured status before go-live.
How much Tech E&O coverage do I need?
Start with what your largest customer contracts require — frequently $1M–$2M — and scale from there based on the size of the clients you serve and the financial harm a failure could cause. An advisor can map your contract requirements to the right limits.
