# E&O vs Cyber Insurance: What’s the Difference?

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.
