Technology errors and omissions insurance (Tech E&O) is a specialized type of professional liability insurance designed to protect technology companies and professionals from claims arising due to mistakes, negligence, or failures in the services they provide. This coverage typically includes defense costs and settlements related to claims of inadequate work, software bugs, data breaches, and other service-related failures. It protects companies from claims from their clients who allege that a technology error or omission caused them financial loss.
