How to prepare for a customer security questionnaire before it arrives: a 10-item readiness kit

To prepare for a customer security questionnaire, write down the ten things buyers ask about most, give one person ownership, and store your approved answers in one place. Do it before the first questionnaire lands, because during a live deal every day of delay is felt by sales.

This guide is for small teams without a security department. It is a readiness kit: what to have, who owns it, and what to do in the first hour when a questionnaire arrives.

The 10-item readiness kit

Almost every standard questionnaire (see our guides to CAIQ, SIG Lite and HECVAT) asks about the same ground. Have these ready, even as a short page each:

1. A written information security policy, with an owner and a review date.
2. An incident response plan, including who decides and how fast you tell customers. See how to answer incident response questions.
3. An access control summary: MFA, how access is granted and removed, and how often it is reviewed. See MFA and access control questions.
4. A data map: what customer data you hold, where it is stored, and who can reach it.
5. A subprocessor list: the vendors that touch customer data.
6. An encryption statement: in transit and at rest, in plain words.
7. Backup and recovery facts: what you back up, how often, and whether you have tested a restore.
8. Employee practices: security training, laptop and device rules, and background checks if you do them.
9. Your assurance position, stated honestly: SOC 2, ISO 27001, a penetration test, or none yet. See the SOC 2 question and the penetration test question.
10. A short company profile: legal name, headquarters, number of staff, hosting provider, and a named security contact.

None of this needs to be long. A reviewer wants a clear statement they can check, not a policy library.

Use a framework as your outline

If you want an outline for the policies, the [NIST Cybersecurity Framework 2.0](https://www.nist.gov/cyberframework) is free and organises security work into six functions: Govern, Identify, Protect, Detect, Respond and Recover. You do not need to adopt it formally. Using its headings is a quick way to check you have not left a whole area empty.

A SOC 2 report is one of the [AICPA's SOC reports](https://www.aicpa-cima.com/topic/audit-assurance/audit-and-assurance-greater-than-soc-2): a CPA firm reports on a service organization's controls. It is one way to prove your controls to buyers, but you do not need one to answer a questionnaire well.

Name one owner

Questionnaires stall when nobody owns them. Pick one person to route questions and sign off answers, usually the CTO or head of engineering at a small company, with sales or operations helping on contract and privacy questions. Our guide on who should answer security questionnaires covers how to split it.

Start your answer library now

Every questionnaire you answer is raw material for the next one. Keep approved answers in a single place with the date and the source document behind each one, and repeat questions take seconds. See how to build a security answer library.

The first hour when one lands

1. Open the file and count the questions. Note the deadline and who at the buyer to contact.
2. Check the format. Excel and CSV are the easiest to answer in place; see how to fill out a security questionnaire in Excel.
3. Ask the buyer what matters most. A short call often saves hours of guessing.
4. Fill in the facts you already know from the kit, then flag the rest for the owner.
5. Plan the time. See how long a security questionnaire takes.

Where Rendro fits

Once your documents exist, Rendro drafts answers from them for each questionnaire you upload, shows the source for every answer, and writes them into the buyer's original file. If you want to judge the quality first, send us the blank questionnaire and we will fill in the first 25 answers free within 48 hours.
