Control evidence examples
Security questionnaire evidence examples by control family
Who this guide is for
B2B SaaS security owners, engineering leaders, operations teams, sales engineers, and founders preparing evidence for customer reviews.
Key takeaways
- Match evidence to the exact claim and system scope.
- Prefer current operating records over policy-only proof.
- Create redacted customer-safe versions before a deal is urgent.
- Record owner, date, sensitivity, and expiry for every artifact.
- Never place secrets or unrestricted technical findings in a questionnaire.
Identity and access management
Useful evidence can include an access-control policy, identity-provider configuration summary, MFA coverage statement, joiner-mover-leaver workflow, recent user-access review record, privileged-access inventory, and a redacted approval example. The evidence should identify which workforce, production, and customer-support systems are covered.
Secure development and change management
Use a customer-safe software-development lifecycle summary, code-review requirements, branch-protection evidence, deployment approval records, dependency-scanning workflow, secure-development training record, and a redacted change ticket. A repository screenshot without scope or date is weak evidence.
Vulnerability management and testing
Potential evidence includes the vulnerability-management policy, scanning cadence, triage workflow, remediation SLA definition, sanitized finding ticket, external assessment summary, penetration-test executive summary, and retest status. Keep automated scanning distinct from penetration testing.
Incident response and monitoring
Provide the incident-response plan, role and escalation summary, exercise record, sanitized alert-to-resolution example, logging coverage summary, on-call procedure, and lessons-learned template. Do not disclose live detection logic, personal data, or incident detail unrelated to the customer's decision.
Resilience, backup, and recovery
Relevant proof includes the backup standard, system coverage record, retention configuration summary, restore-test result, business-continuity exercise record, recovery objectives, and remediation from a failed test. A statement that backups are enabled does not prove they can be restored.
Privacy, data governance, and suppliers
Use a data-flow summary, retention and deletion procedure, subprocessor register, vendor-review record, data-subject request workflow, privacy training record, and customer-safe contractual summaries. Legal and privacy owners should approve these representations.
Evidence examples by control family
| Control family | Stronger evidence | Common weak substitute |
|---|---|---|
| Identity and access | Recent access review, MFA coverage, privileged-access record | An access policy with no operating record |
| Secure development | Reviewed change record, branch rules, dependency triage example | A generic SDLC diagram with no current scope |
| Vulnerability management | Dated assessment summary, remediation ticket, retest status | An unreviewed scanner export |
| Incident response | Exercise record, role matrix, sanitized incident workflow | An untested response-plan document |
| Backup and recovery | Successful restore-test record with scope and date | A screenshot showing backups are enabled |
| Vendor management | Risk-tiered review record and current subprocessor register | A vendor list with no review evidence |

Is a policy enough evidence?
A policy can support governance intent, but many control claims also need current operating evidence showing that the process occurs.
Can screenshots be used as evidence?
Yes, when they are current, scoped, redacted, understandable, and approved. A screenshot should not expose secrets, personal data, or unnecessary configuration detail.
Should every customer receive the same evidence?
No. Share the minimum approved material appropriate to the buyer's risk decision, relationship, confidentiality controls, and contractual rights.
