Coverage description
An Insurance Services Office (ISO) standard form. It covers bodily injury and property damage caused by a cyber incident under the umbrella, subject to its own each cyber incident occurrence limit and aggregate limit, and excludes notification, monitoring, forensic, restoration, extortion and similar cyber incident costs.
How the form has changed
The 06 26 edition is restructured to work with the cyber incident and access or disclosure exclusions in the umbrella coverage part, setting those exclusions aside for Coverage A instead of repeating its own exclusions and definitions. The coverage it grants is the same.
