Who it's for
Technical founders or engineering leads at a small B2B SaaS company preparing a first customer security review, with no dedicated security team but enough access to inspect infrastructure, code, contracts, and vendors.
Who it's NOT for
Teams seeking ISO 27001 or SOC 2 certification, a penetration test, a full GDPR compliance program, or legal advice on a disputed processing role. It also will not rescue a same-day deadline if nobody can verify the underlying controls.
About this playbook
Your first security questionnaire usually arrives during a live deal, when nobody has time to build a security program from scratch. The dangerous shortcut is to answer from memory, copy a cloud provider's claims, or turn planned work into a confident “yes.” That creates contradictions the buyer will spot and promises your company may later have to honor. This playbook gives a technical founder one evidence-first route through the request. You will set the assessed service boundary, map customer data and suppliers, index the records you already have, and write short answers that separate implemented controls from gaps. EU privacy questions are handled by processing role and actual transfer path, not by a blanket “GDPR compliant” claim. The finish line is not a perfect score. It is a response pack your company can defend: each material answer has an owner and evidence pointer; each weak control has an honest status and dated action; legal or contractual exceptions are isolated for review. You also keep a reusable library so the next questionnaire starts from verified facts rather than another blank spreadsheet.
What you'll do, step by step

Do not start in row one. First make the request stable, name the boundary, and decide how incomplete answers will be recorded.
- 1Freeze a working copy and log the deadlineFree preview12 min
Save the untouched customer file, create a dated working copy, and record who submits and who approves it. Capture the deadline, required format, portal limits, and any NDA condition in the same note.
You're done when
An untouched original, a versioned working copy, and a short intake note naming the deadline, submitter, approver, and delivery constraints.
Watch out
Editing the only copy destroys your audit trail. If the customer later challenges an answer, you need to know exactly which question wording you received.
- 2Define the assessed service boundaryFree preview35 min
Write one paragraph naming the SaaS service, production environment, customer-facing features, support tooling, and customer data in scope. State whether the company is acting as controller, processor, or both for the relevant activities; do not assign one role to the whole company by habit.
You're done when
A scope paragraph that another engineer can use to decide whether a system, vendor, or control belongs in this response.
Tip
Put exclusions in writing now. Corporate laptops may matter to access control while an unrelated marketing site may not belong in the assessed service.
Watch out
A fuzzy boundary produces incompatible answers. One row describes the product, the next describes the cloud provider, and the customer cannot tell which controls you operate.
- 3Tag every question before answeringFree preview45 min
Add working columns for domain, internal owner, evidence, answer status, and reviewer.
Use a fixed status set:
- implemented
- partially implemented
- planned
- not applicable
- unknown.
Tag the whole sheet before drafting prose so duplicate questions and missing owners become visible.
- Add the five working columns
- Apply the status vocabulary
- Group duplicates without deleting customer rows
- Assign one accountable owner per domain
You're done when
Every questionnaire row has a domain, owner, evidence need, and provisional status; no row is silently skipped.
Tip
CSA's CAIQ is useful for recognizing common cloud-control domains, but keep the customer's wording and row identifiers intact.
Details
What you need first
The customer's questionnaire and deadline; access to cloud and identity configuration; current vendor, privacy, and contract records; one technical approver; and authority to flag gaps instead of inventing answers.
