E&O covers claims over professional-service errors; cyber insurance covers defined data incidents and may include response, recovery, and privacy liability. A failed service and a security incident trigger different questions: E&O asks whether professional work caused a customer loss, while cyber wording may cover your response costs, data restoration, interruption, or privacy claims. Compare covered losses, vendor coverage, waiting periods, sublimits, and which policy responds first. A package quote still has separate grants and limits. ## More Questions About Professional Liability, E&O and Tech E&O - [E&O vs D&O Insurance: How Do They Differ?](https://thegeneralaverage.com/insurance-faq/professional-liability/eo-vs-do) - [Tech E&O vs Cyber Insurance: What’s the Difference?](https://thegeneralaverage.com/insurance-faq/professional-liability/tech-eo-vs-cyber) - [Tech E&O vs Professional Liability: Is There a Difference?](https://thegeneralaverage.com/insurance-faq/professional-liability/tech-eo-vs-professional-liability) - [Tech E&O vs Product Liability: Which Applies to Software?](https://thegeneralaverage.com/insurance-faq/professional-liability/tech-eo-vs-product-liability) ## Coverage Guides Related to Professional Liability, E&O and Tech E&O - [Professional errors and omissions (E&O)](https://thegeneralaverage.com/coverage/professional-errors-omissions) - [Technology errors and omissions (E&O)](https://thegeneralaverage.com/coverage/technology-errors-omissions) - [Cyber liability](https://thegeneralaverage.com/coverage/cyber) ## Sources for This Answer 1.
