Analysis of cyber coverage disputes identifies a consistent leading cause: a control failure that directly contributed to the incident, where the control had been represented as in place at policy inception. Insurers now commonly require multi-factor authentication, endpoint detection, offline backups and an incident response plan as baseline conditions.
Attestation Is A Point-In-Time Claim About A Moving System
An organisation completes a proposal form in, say, March, answering that multi-factor authentication is enforced. It is true in March.
By November an acquisition has brought in an estate without it. A legacy application needed an exemption. A support portal was excluded because enrolling thousands of external users was impractical — precisely the exemption that produced the PowerSchool breach filed at 26-0113.
None of those is a lie at the time it is made. All of them make the attestation false by the time it matters.
The Exemption And The Intrusion Route Are The Same Thing
This is what makes the dispute pattern so consistent. Attackers find the system without the control for the same reason the organisation left it out: it was the awkward one.
So the control gap that voids the coverage is very often the exact gap the intrusion used. The insurer is not hunting for an unrelated technicality; the causal link is genuinely there.
What Follows For A Security Function
It makes the exemption register a financial document. Every accepted exception now has a potential insurance consequence, and someone should be able to produce, on any given day, the list of systems outside each attested control.
Most organisations cannot. That is a more useful thing to fix than the coverage argument, because it is the same list an incident responder will want.
