A software company can face two very different kinds of loss from one incident. A coding defect may cause a customer’s system to stop operating, creating a contract or negligence claim. If the same defect also exposes personal data, the company can face forensic investigation, notification, privacy liability and regulatory costs.
That is why technology firms should not assume a generic professional liability policy or a generic cyber policy automatically addresses the entire exposure.
What does Technology E&O cover?
Technology E&O is a form of professional liability coverage designed around technology services and products. Depending on the form, it can respond to allegations of negligence, errors, omissions, failure to deliver contracted technology services, software performance failures or other covered professional mistakes that cause a customer financial loss.
The Hartford describes Tech E&O as protection for technology companies facing liability from errors and omissions in their services, while distinguishing it from cyber liability protection for attacks and accidental data leaks.
What does cyber insurance cover?
Cyber insurance can include both first-party and third-party coverage. First-party benefits may address incident response, forensic investigation, data restoration, business interruption, cyber extortion and crisis services. Third-party coverage can address privacy or network-security liability claims, subject to policy terms.
The NAIC notes that cyber policies are highly customized and that ordinary commercial property and general liability policies generally do not address many cyber risks. This makes side-by-side wording review especially important.
| Example loss | Coverage area most likely to matter |
|---|---|
| Software fails and causes a customer’s financial loss | Technology E&O |
| Customer database is breached | Cyber/privacy coverage |
| Ransomware shuts down internal systems | Cyber first-party coverage |
| Cloud service outage causes client losses | Could involve Tech E&O, cyber business interruption or both depending on cause and wording |
| Security flaw in delivered software exposes client data | Potential overlap between Tech E&O and cyber liability |
Why SaaS companies often need both
A SaaS company promises performance and handles data. A prolonged platform outage may trigger service-level obligations and customer claims even without a security breach. A cyberattack can create its own response costs and privacy liabilities. Because the exposures overlap operationally, many insurers package Tech E&O and cyber together or coordinate them within a technology policy.
Important contract issues for tech firms
Insurance should be reviewed alongside customer contracts. Technology agreements can contain indemnification clauses, service-level commitments, limitation-of-liability provisions, data-security warranties and insurance requirements. A policy cannot be evaluated properly without understanding what the company has promised customers.
- Compare the policy definition of technology services with the services actually sold.
- Check whether software, consulting, hosting, managed services and implementation work are all included.
- Review contractual-liability exclusions and any carve-backs.
- Confirm treatment of subcontractors and cloud providers.
- Review retroactive dates for claims-made coverage.
- Understand notification requirements after an incident or potential claim.
First-party vs. third-party confusion
Tech E&O is primarily associated with liability to customers and other third parties, while cyber insurance can include substantial first-party expenses incurred by the insured business itself. That distinction is useful but not absolute. Combined technology policies can blur the boundaries, and some cyber forms include technology professional liability modules.
What about general liability?
General liability is important for bodily injury, property damage and certain advertising or personal-injury claims, but it should not be assumed to replace specialized cyber or Tech E&O protection. The NAIC notes that many cyber risks are outside traditional commercial property and general liability coverage.
How to compare Tech E&O and cyber quotes
- Match the revenue and service descriptions used in underwriting.
- Compare limits, retentions and sublimits for cyber extortion and business interruption.
- Check whether dependent business interruption for key vendors is included.
- Review waiting periods for system interruption.
- Compare breach-response vendors and consent requirements.
- Ask how one incident involving both service failure and a security event will be allocated.
Frequently asked questions
Is Tech E&O the same as cyber insurance?
No. They address different core risks, although policies can overlap or be packaged together.
Does a software company need Tech E&O if it already has cyber coverage?
Cyber coverage may not address a non-cyber software or professional-service failure that causes a customer financial loss. Review the form rather than relying on the policy title.
Can one incident trigger both coverages?
Yes. A technology failure can also create a security or privacy event, making coordinated wording important.
Are these policies claims-made?
Many professional and cyber liability forms are claims-made or claims-made-and-reported, but the exact trigger and reporting requirements vary.
