Vendor responses become binding contractual representations with executive certification. Use during vendor due diligence, third-party risk management, procurement security review, or subprocessor evaluation.

Vendor Security Assessment Questionnaire

Generates a pre-contract due-diligence questionnaire for evaluating vendor security controls, data practices, and compliance across GDPR, CCPA, HIPAA, SOX, GLBA, FERPA, and industry frameworks.

Quick Start

Gather before drafting:

  1. Vendor scope — data types accessed (PII, PHI, PCI, financial, proprietary), processing activities, data flows
  2. Applicable regulations — GDPR, CCPA, HIPAA, SOX, GLBA, FERPA, or sector-specific
  3. Risk tolerance — what constitutes acceptable vs. disqualifying vendor risk
  4. Contract alignment — security provisions to incorporate by reference

Document Framework

ElementRequirement
PreambleCompletion mandatory pre-contract; responses are binding representations
Executive certificationSenior officer (CISO/CTO/CLO) attests accuracy; signature block required
Submission deadline10–15 business days
Change notificationVendor notifies within 5 business days of material security changes
ConfidentialityQuestionnaire and responses treated as confidential business information

Assessment Domains

Draft numbered questions per domain. Each question includes a response field and evidence-request field where applicable. Tailor scope to data sensitivity — not every vendor needs every domain.

1. Information Security Governance

  • Dedicated CISO/equivalent; certifications (CISSP, CISM, CISA)
  • Framework alignment (NIST CSF, ISO 27001, CIS Controls, COBIT)
  • Policy review cadence; security awareness training (all-staff + specialized)
  • Board-level security reporting frequency

2. Data Classification & Lifecycle

  • Classification taxonomy compatibility with client's scheme
  • All data storage/processing locations (primary, DR, backup, cloud regions)
  • Cross-border transfer mechanisms (SCCs, adequacy decisions, BCRs)
  • Retention post-termination; destruction methods; certificates of destruction
  • Backup frequency; encrypted backup media; tested RTO/RPO

3. Access Control & Privileged Access

  • MFA enforcement across all access; supported factors
  • RBAC, least-privilege, segregation of duties
  • Privileged access: JIT elevation, session recording, auto-deprovisioning
  • Access recertification frequency; anomalous-access alerting

4. Vulnerability Management & Testing

  • Scanning tools, frequency, and patching SLAs:
SeverityPatch SLA
Critical≤ 24–72 hrs
High≤ 7 days
Medium≤ 30 days
Low≤ 90 days
  • Annual third-party pentests (external + internal lateral movement)
  • AppSec testing (SAST, DAST, SCA) for custom software
  • Bug bounty / responsible disclosure program
  • Request most recent pentest summary and remediation status

5. Incident Response & Business Continuity

  • Documented IR plan with roles, escalation, communication protocols
  • IR testing frequency (tabletop, simulations) and recent results
  • Notification timeline — must allow client to meet most restrictive regulatory deadline (GDPR 72 hrs, HIPAA 60 days, state breach laws)
  • Cooperation with client IR team and legal counsel
  • Cyber insurance: policy limits, third-party liability, adequacy for data volume
  • BCP/DR: tested RTO/RPO, geographic diversity, multi-scenario resilience

6. Encryption & Key Management

  • At rest: minimum AES-256; scope includes production, dev/test, backups, portable media
  • Database encryption approach (TDE, column-level, application-layer)
  • In transit: TLS versions, deprecated protocol status, enforced cipher suites
  • In use: confidential computing / secure enclave capabilities (if applicable)
  • Key management: HSM/KMS storage, rotation frequency, secure destruction

7. Network Security & Segmentation

  • Customer isolation; production vs. corporate separation
  • Zero-trust architecture status
  • Perimeter controls: firewalls, IDS/IPS, WAF, DDoS protection
  • Remote access: VPN, NAC/device posture, MFA
  • Assessment cadence (external scans, internal pentests, wireless)

8. Subprocessor Risk Management

  • Complete subprocessor inventory: role, data access, location, assessments conducted
  • Flow-down of security requirements (contractually at least as stringent as client's)
  • Client notification and approval rights before new subprocessor engagement
  • Right to terminate non-compliant subprocessors

9. Certifications & Compliance

  • SOC 2 Type II: report date, principles, opinion status, scope alignment
  • ISO 27001: certificate dates, scope, certification body
  • PCI DSS, FedRAMP/StateRAMP, HITRUST, TISAX (as applicable)
  • Regulatory compliance confirmation for applicable data types
  • Commitment to provide updated reports/certifications annually

10. Physical Security & Environmental Controls

  • Data center access: MFA, visitor logs, surveillance, security personnel
  • Background checks for personnel with physical access
  • Environmental: fire suppression, UPS, generators, climate, water detection
  • Facility certifications (SSAE 18 SOC 1, Uptime Institute tier)

11. HR Security & Insider Threat

  • Background checks; periodic re-investigation for sensitive roles
  • Security training before access; policy acknowledgment
  • Offboarding: access revocation timeline, exit procedures
  • Insider threat monitoring; DLP for exfiltration prevention

Risk Assessment Framework

Score vendor responses after receipt:

RatingCriteria
LowControls meet/exceed requirements; evidence provided
ModerateMinor gaps; addressable via contractual provisions
HighSignificant gaps; requires remediation plan with deadlines
CriticalFundamental deficiencies; disqualifying absent remediation

Assessment report must include:

  • Per-domain and overall risk rating with justification
  • Recommended contractual controls (audit rights, insurance minimums, SLAs)
  • Evidence gaps requiring follow-up
  • Go/no-go recommendation with conditions
  • Flagged inconsistencies between responses and publicly available information

Checks

  • State explicitly in preamble: responses are contractually binding representations; incomplete/misleading answers constitute grounds for disqualification or material breach
  • Align notification timelines with the most restrictive applicable breach notification law
  • Mark questions as required vs. conditional based on data type (PCI questions only if payment data involved)
  • Flag vendors refusing to disclose subprocessors or share certifications as elevated risk
  • All legal citations to specific regulatory provisions must be verified against current law [VERIFY]
