Tech E&O vs. Cyber Insurance: What If the Software Fails Without a Breach?

A software deployment fails and a client cannot process orders. There is no known attacker and no confirmed data breach. The client alleges that your implementation caused a financial loss.

That scenario raises a technology errors and omissions question, not automatically a cyber-breach question. Tech E&O and cyber coverage can overlap, but they should not be treated as interchangeable names. Travelers distinguishes claims arising from technology services from cyber-related liability and first-party breach expenses. [1]

Start with the event and the alleged harm

Describe what happened before trying to choose a policy. Was the allegation about a faulty service, a security failure, disclosure of information, interruption to your own systems, or several of those at once?

Technology E&O can address covered allegations involving errors, omissions or negligence in technology products and services. Travelers’ technology-risk guidance identifies this as an exposure that general liability does not ordinarily address. [2]

Cyber coverage can have both first-party and third-party components. The exact incidents, services and expenses included depend on the form, rather than the generic word “cyber.” [1]

Use three illustrative scenarios

These examples are review prompts, not NRG claims or assurances of payment.

A failed integration. A connector transfers incorrect order information, and the customer claims lost revenue. Ask whether the technology service and alleged error fall within the E&O wording, including any relevant exclusions.

A breach of your own systems. Unauthorized access exposes business information. Ask which cyber provisions address the incident, response expenses and potential third-party allegations.

An error with a security consequence. A configuration mistake is alleged to have exposed a client’s data. Ask whether both professional-services and cyber provisions may be relevant, how notice should be given, and how the policies interact.

The exercise should produce a coverage map and open questions—not a rule that every technical failure belongs exclusively in one box.

Check the definition of your services

Give the reviewer a current description of the work: software development, managed services, implementation, hosting, security work, support or another activity. Identify changes since the last application and any service delivered through subcontractors.

Ask how the policy describes technology products and professional services, and whether that description reflects the business. A policy for yesterday’s narrower operation may need review when the work changes.

This is especially useful for an IT firm adding ongoing monitoring to a one-time implementation service. Do not assume the same description answers both engagements.

Review combined products carefully

Some insurers offer E&O and cyber within a combined product. Corvus’s published Smart Tech E&O material is one example; it describes its own combination of cyber and technology/professional-services protection. [3]

That does not establish that every E&O product includes cyber, or that every combined policy uses the same limits. Ask whether limits are separate or shared, how retentions work, and whether one event can involve more than one coverage part.

Compare the actual arrangement rather than treating “combined” as automatically broader or less expensive.

Read the contract alongside the policy

A client’s contract may contain insurance requirements, service promises, indemnities or limitations of liability. Give the broker the insurance clauses and have a lawyer address the contractual commitments.

Ask specifically about responsibilities that go beyond ordinary service delivery, such as guarantees, unusually broad indemnities or obligations relating to a subcontractor. Do not assume that a clause is insured simply because both parties signed it.

Use the insurance quote comparison guide to organize differences without comparing premiums in isolation.

Confirm the reporting path before an incident

Keep the claim-reporting contacts and incident-response instructions where responsible staff can find them. Ask what must be notified, when, and whether the insurer requires approval for particular advisors or expenses.

Where two policies may be relevant, obtain guidance about notifying both rather than informally selecting one and ignoring the other. Follow the relevant policy conditions and preserve factual records without delaying necessary safety or security action.

Ask for a service-specific review

NRG’s cyber insurance and professional liability pages are starting points. Send an inquiry with the services you provide, operating states and the kind of contract requirement involved.

The useful question is not “Which one is better?” It is “Which allegations and expenses does each policy address for the work we actually do—and what remains outside them?”
