Vendor Security Logging and Detection Questionnaire

An editable 17-page field guide for the analyst who has to know, before an incident, whether a vendor logs the events that matter and can retrieve them months later. Every item explains why it matters, the result a good answer should produce, the evidence to request, and the next analyst move.

What’s inside

• A readiness page confirming the vendor entity, product, environment, region and service in scope, business criticality and data sensitivity, the internal owners who can validate each claim, and how restricted evidence will be handled
• Twenty-eight numbered items, VLD-01 to VLD-28, grouped into 7 control domains
• Scope Governance and Responsibility; Security Telemetry Coverage; Event Quality Pipeline and Integrity; and Retention Access and Evidence
• Detection Engineering; Monitoring Triage and Investigation; and Validation Improvement and Assurance
• Response, evidence reference, action owner and due date against every item, so the completed form is the assessment record rather than a questionnaire you transcribe later
• A rapid final checklist that restates all 28 questions on one page for the closing challenge

The assessment rule is written into the form: evidence should be current, complete for the service in scope, usable by your organization, tested where capability matters, and linked to a decision. A certificate, policy, screenshot or vendor statement is not enough on its own when it does not prove the specific requirement.
