After reading, you can send questionnaires suited to the risk, and build a library that answers them fast and truthfully.
Definition
Buyers use their own lists or shared ones, such as the SIG from Shared Assessments or the CAIQ from the Cloud Security Alliance. Answers often end up in the contract, which gives them weight.
Why it matters
For a buyer, it is a low-cost way of comparing suppliers. For a supplier with nothing prepared, it can hold up a deal for weeks.
Its limit is that the answers are self-declared, so evidence and contract terms must back up whatever matters most.
How it works
If you are sending one, fit it to the tier: a short list for low risk, the full list only for critical suppliers. Ask for evidence on the important points, and read the answers.
If you are answering, keep a library of approved answers, each with its evidence and owner, and update it after every relevant change.
Answer exactly what is asked. Where a practice is only partial, say so and explain the compensating control.
A worked case
A 50-person SaaS company receives about four questionnaires a month, of about 200 questions each. It builds a library of 150 approved answers and a trust page carrying its ISO/IEC 27001 certificate.
Average answer time drops from nine days to two, and sales only involve security when a question is new.
Good practices
- Have someone who knows the practice approve each answer.
- Date your answers and review them once a year.
- Share evidence under a confidentiality agreement.
- Turn questions that keep coming back into public documents.
Common mistakes
- Answering yes to everything to close the sale. Those answers can come back as contract terms.
- Reusing an old answer after the practice has changed.
- Sending 300 questions to a small supplier of low-risk services.
- Collecting answers and never reading them, which wastes everyone's time.
Questions
- What is the SIG questionnaire?
- The Standardized Information Gathering questionnaire from Shared Assessments, widely used for supplier reviews.
- What is the CAIQ?
- The Consensus Assessments Initiative Questionnaire from the Cloud Security Alliance, intended for cloud providers.
- Can a certificate replace a security questionnaire?
- It can shorten one, particularly when the scope fits. Many buyers still ask for specifics.
- Are questionnaire answers legally binding?
- They can be, particularly if the contract refers to them, and a false answer can amount to misrepresentation.
- Can AI fill in security questionnaires?
- It can draft from your approved answers. Someone who knows the practice should still check them.
