MSP and MSSP Security Questionnaire

An editable 18-page field guide for the analyst assessing a provider that already holds privileged access to your estate, where a compromise of the provider is a compromise of you. 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
• Thirty-two numbered items, MSP-01 to MSP-32, grouped into 8 control domains
• Service Scope and Shared Responsibility; Workforce and Privileged Access; RMM, Automation, and Tenant Isolation; and MSSP Monitoring and Detection
• Managed Operations and Change; Logging, Evidence, and Service Reporting; Incident Response and Recovery; and Supply Chain, Resilience, and Exit
• 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 32 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.
