What is Security Questionnaire Software
Security questionnaire software is a category of applications used by vendors to respond to customer information-security and data-protection assessments. It centralises approved answers, routes questions to security and engineering owners, and exports responses in the requester's format.

What security questionnaires cover
Security questionnaires assess a vendor's information security posture across topics such as access control, encryption, secure development, incident response, vulnerability management, business continuity and data handling. Common formats include the SIG, CAIQ, and bespoke customer questionnaires.
What the software does
Security questionnaire software supports the response process. It imports incoming questionnaires, suggests previously approved answers, routes questions to the relevant security, engineering or compliance owners, and exports the response back to the requester's format. The answer library typically references the underlying controls and evidence held in a security or GRC system.
Typical capabilities
- Versioned answer library with control references
- Mapping between answers and frameworks (ISO 27001, SOC 2, NIST, CSA STAR)
- Import from common questionnaire formats
- Routing to security, engineering and legal owners
- Evidence attachment and audit trail
- Export to requester format and customer portals
Why centralised answers matter
A single security questionnaire can contain several hundred questions, and a vendor may receive many of them per year. Centralising approved answers reduces inconsistency between responses, ensures alignment with current control descriptions, and shortens the time required to complete each assessment.
