Late notice is one of the most avoidable reasons a cyber claim runs into trouble. Policies ask you to notify the insurer as soon as practicable, and some make written notice a condition of cover. Delay can reduce what the insurer pays, especially when the delay made the loss bigger.
The rules differ by policy. Who counts as knowing, which channel counts as notice and what you must include all vary. Use this checklist to set up your process before an incident, and to follow it during one.
Before an incident: set up the route
When something happens: notify promptly
What to put in the notice
After notice: protect the claim
Broker's tip
When in doubt, notify. An early call about something that turns out to be minor usually costs little, and a late call about something serious is much harder to put right. Notifying is a separate step from making a claim, and on many policies the first call also brings expert advice. Ask your broker to walk your control group through the notification clause once a year, so everyone knows the route before they need it.
