In Depth
A technology product is supposed to do a defined thing. Sometimes it does not, the customer loses money, and the policy pays the resulting claim along with the cost of defending it. Tech E&O sits at the seam between two older forms of coverage. General liability handles bodily injury and property damage. Professional liability handles bad advice. Tech E&O covers the space in between, where a product or service simply fails to work and causes a purely financial loss.
The failures it contemplates are the familiar ones in software and IT: outages, defects, integration problems that break a customer's systems, data loss, and delays or errors in a managed service. Many Tech E&O policies also fold in a measure of cyber coverage, since a security incident is one common way a technology service fails its customers, though standalone cyber policies usually go deeper on that risk.
Coverage is normally written on a claims-made basis, meaning the policy that responds is the one in force when the claim is made, not when the work was done. That makes continuity important. Let the coverage lapse and you can lose protection for services you delivered years earlier.
What It Looks Like
A vendor runs a hosted platform that a retailer relies on to process orders. A faulty update corrupts a batch of transactions, and the retailer over-refunds customers for a week before anyone catches it. The retailer demands the lost money back. The vendor files with its Tech E&O carrier, the policy responds to the claim, and it also funds the lawyers defending the vendor as the two sides work out how much is actually owed.
Why It Matters For AI Vendors
Tech E&O is the coverage most technology companies are expected to carry, and it is one of the first things an enterprise customer's procurement team asks to see. A single failed deployment or corrupted dataset can trigger a claim far larger than the fee the customer ever paid, so the policy is often what keeps an ordinary service mistake from turning into a loss the business cannot absorb. It is also frequently a contractual requirement, written into the master service agreement before a deal can close.
