Security Information Questionnaire
What a Security Information Questionnaire Is and When it’s Used
Why a Clear SIQ Matters for Compliance and Risk Management
A well-structured SIQ standardizes vendor security disclosures, reduces repetitive requests, and creates an auditable record for procurement and compliance teams. It helps demonstrate due diligence for HIPAA, FTC, and other regulatory expectations while supporting faster risk decisions.
Who Completes and Reviews the Security Information Questionnaire
Different teams participate in issuing, completing, and reviewing SIQs depending on organizational structure and the sensitivity of the data involved.
- IT Security: Prepares technical responses, lists controls, and documents encryption, patching, and access management.
- Procurement / Vendor Management: Issues the questionnaire, consolidates responses, and tracks remediation requirements.
- Legal / Compliance: Reviews attestations, confirms contractual language, and verifies regulatory alignment.
Clear role separation speeds review cycles and ensures technical answers are validated by qualified personnel before submission.
Typical Signers and Their Responsibilities
CISO — Chief Information Security Officer
The CISO or delegated security lead reviews and certifies SIQ accuracy, provides context for high-risk items, and approves any attestation language. They coordinate remediation commitments and escalate material deficiencies to procurement and legal teams when needed.
Vendor Authorized Signer — VP/Director
An authorized executive or director signs to confirm the questionnaire responses are accurate and complete. Their signature binds the vendor to any representations and is required for formal acceptance and contracting.

Consequences of Incomplete or Incorrect SIQ Responses
Common Mistakes That Slow SIQ Approval
- Providing vague or high-level answers without attachments forces repeated follow-up and lengthens review cycles.
- Submitting outdated certificates or expired SOC/ISO reports causes reviewers to request current evidence.
- Using a generic signer without authority leads to re-signing and contractual delays.
- Omitting contact details for remediation owners prevents timely validation of corrective actions.

Frequently Asked Questions About the Security Information Questionnaire
-
Can the SIQ be signed electronically?
Yes. Under the ESIGN Act (15 U.S.C. ch. 96) and UETA (where adopted), electronic signatures are legally equivalent to handwritten signatures for most transactions, provided the parties consent to electronic records.
-
What evidence should accompany an SIQ?
Attach relevant artifacts such as SOC reports, ISO certificates, architecture diagrams, and policy excerpts. Evidence should be current and timestamped to avoid additional verification requests.
-
Who must sign the completed SIQ?
An authorized representative with authority to make representations for the vendor must sign. Legal or procurement teams often require a named executive or delegated signatory.
-
How long should signed SIQs be retained?
Retain SIQs according to contract lifecycle and regulatory needs: a minimum of 3 years for tax-related records (IRC §6501(a)) and 6 years for HIPAA-related records (45 CFR §164.530(j)), unless a longer period applies.
-
What if the vendor's security posture changes after submission?
Require prompt update and, where material, immediate disclosure. Contract language commonly requires notification and remediation obligations; document updates should be versioned and re-signed if needed.
-
Is notarization or witnessing normally required?
Not generally for SIQs. Specific documents attached to an SIQ (affidavits or jurisdictional attestations) may require notarization; state requirements vary, so check the recipient state's rules.
