Security evidence gap
A control without evidence remains difficult to defend.
The review distinguishes between a poorly documented existing control, evidence that is too narrow, and a genuine technical gap.

To be addressed firstSee the corresponding pathway →
What indicates that you are affected
- Repeated requests for supporting documents
- Scattered evidence
- Gap between policies and technical exports
What weakens the client relationship
- Screenshots with no date, source or scope
- Collection only in a crisis situation
- Real work overlooked during the audit
- Documentary gap masking a technical shortcoming
Decision to be obtainedAn evidence index with source, scope, owner, restriction, verification level and review date.
The conclusion states what the item demonstrates, what remains outside its scope and the decision needed to close the gap.
Review logic
From a disputed claim to qualified evidence or an explicit reservation.
The sequence starts from the contested claim and preserves the scope of each item through to the final decision.
01Diagnose
Distinguish between evidence that is missing, too narrow, or a failing control.
02Qualify
Add source, scope, date, owner and restriction.
03Link
Identify the commitments genuinely supported by the document.
04Maintain
Organise renewal and alerting before expiry.

Anatomy of a piece of evidence
The file alone demonstrates almost nothing.
Source, scope, freshness, restriction and level of verification turn an isolated item into a defensible piece of evidence.
Items to be gathered
Prepare the file before widening the review.
- The response or control whose evidence is disputed or missing
- The deadline and the associated commercial decision
- Commitments already communicated to the parties concerned
- The individuals able to explain how things actually work
- The available evidence, including where it is partial
- Exceptions, incidents or remediations already known
Collection only in a crisis situation
Indicative timeline
Until acceptable evidence is obtained
Distinguish between producing a document, qualifying it and validating it within scope.
Symptom
A client requests evidence; the team spends two days reconstructing it, under pressure.
Diagnosis
A poorly documented existing control, evidence that is too narrow, or a genuine gap: the three cases must be handled differently.
Construction
The evidence index is built up: source, scope, date, owner, restriction, verification level.
Permanent regime
The next request costs hours, then weeks — and expiries warn you before clients do.
Consistent intervention
Evidence and remediation programme
Correct the technical gaps and build the evidence that will make it possible to defend them. The disputed response, the evidence available and the deadline make it possible to determine whether the issue lies with the control, the sample or the qualification of the evidence.
