Attestation Drift Monitor
You attested to controls at bind — MFA everywhere, full EDR, tested backups. A year later, EDR coverage has slipped, MFA has new exceptions, the restore test is overdue. That drift can quietly turn a valid policy into a rescission argument mid-term. Enter where each control was at bind vs now and see where you have drifted into risk. Educational, not insurance advice.
A control you attested at bind has decayed below where it was warranted. If a loss touches it, the insurer may argue the warranty was breached. Restore the control, or notify your broker and update the position.
What this monitor does
- Controls you attested to at bind (MFA everywhere, full EDR, tested backups) decay over the policy year — and that drift can turn a valid policy into a mid-term rescission argument.
- Enter each control’s level at bind vs now and the monitor flags where you have drifted below the position you warranted, or breached a safe floor.
- Turns a one-time application snapshot into a living metric you can watch between renewals.
- Transparent model on your own numbers; not insurance advice.
Why this matters
The cyber application is a snapshot; your environment is a moving target. The controls you truthfully attested to at bind decay in a hundred small, operational ways over the year — and because those answers can function as continuing warranties, the decay is not just a security problem, it is a coverage problem. A post-breach forensic review that finds EDR was on 88% of machines, not the 100% you warranted, is where claims get contested.
This monitor makes drift visible so you can treat attested controls as live metrics and fix slippage before it matters. It is a model, not insurance advice; how your policy treats post-bind change depends on its wording.
Frequently asked questions
Can my cyber policy be voided if controls slip after I bind it?
Potentially, where the application answers are treated as continuing warranties or where a control is written as a condition precedent. If you attested that MFA was enforced on all accounts and, months later, exceptions crept in and a breach came through one of them, the insurer may argue the warranted position was not maintained. Not every policy works this way, and much depends on the wording and jurisdiction, but the safe assumption is that the controls you attested to need to stay true for the life of the policy — not just on the day you signed. Monitoring drift is how you keep that assumption honest.
What is "attestation drift"?
It is the gradual gap that opens between the security posture you described on the application and your actual posture later in the policy period. EDR coverage slips as new machines are onboarded without the agent; MFA gains "temporary" exceptions that never get removed; the restore test that was current at bind goes months overdue; patch SLAs quietly slide. Each change is small and operational, but together they can move a material control below where you warranted it — exactly the kind of thing a post-breach forensic review surfaces.
How do I prevent drift from hurting a claim?
Treat the attested controls as living metrics with owners and alerts, not a bind-day snapshot: monitor MFA and EDR coverage continuously, keep the restore test on schedule, and track patch-SLA compliance. When a control slips materially, either restore it promptly or notify your broker and document the change so the record reflects reality. The goal is that if a claim is ever examined, your actual posture matches — or exceeds — what you told the insurer.
Is this insurance advice?
No. It is an educational model that helps you visualise drift between your attested and current control levels so you can act on it. Whether and how a given policy treats post-bind changes depends on its specific wording and the law of your jurisdiction. Confirm your policy’s warranty and condition-precedent provisions with your broker or coverage counsel.
