Client security questionnaires: how to respond without a CISO

The security questionnaire: mandatory step in B2B sales

You're about to close an enterprise client. The contract is almost signed. Then comes the security questionnaire: 50, 100, sometimes 200 questions about your security practices, GDPR compliance, and incident management. Without a CISO or security team, it's panic time.

The typical blocking questions

"Do you conduct regular security tests?" — If the answer is no, it's often disqualifying.

"Do you have a recent security audit report?" — The report is the tangible proof.

"How do you manage data access control?" — You need to describe concrete mechanisms (RLS, RBAC, auth middleware).

"What is your vulnerability management policy?" — Expected: a process for detection, prioritization, and remediation.

"How do you notify in case of a data breach?" — CNIL notification procedure within 72h.

The strategy: the audit report as your answer

Rather than answering question by question without proof, attach a recent audit report. It answers 60-70% of technical questions at once and proves you take security seriously.

Here's how to structure your responses:

Security testing: "We conduct regular security audits by a third party. See attached report dated [date]."

Access control: "Our mechanisms are detailed in section [X] of the audit report. Identified flaws have been remediated (see remediation plan)."

Vulnerability management: "Our process includes regular external reviews, severity-based prioritization, and remediation tracking. Details in appendix."

The 5 documents that replace a CISO

1. Security audit report (our Full Audit at €4,200)

2. Security policy (2-3 pages describing your practices)

3. Breach notification procedure (CNIL template)

4. GDPR processing register (mandatory anyway)

5. Business continuity plan (backup, recovery, RTO)

The ROI of a successful questionnaire

A security questionnaire that blocks a €50,000/year sale costs infinitely more than the €4,200 audit that lets you respond. This is the most concrete argument for justifying a security audit.
