What security questionnaires actually are
When an enterprise client — a bank, telco, or large corporate — evaluates your fintech as a vendor, their IT risk or procurement team will send you a security questionnaire. This is a structured assessment of your security posture, covering everything from encryption and access controls to incident response and compliance certifications.
These questionnaires come in various formats: proprietary spreadsheets, SIG (Standardized Information Gathering) questionnaires, CAIQ (Consensus Assessment Initiative Questionnaire) for cloud, or custom forms aligned with the client's internal risk framework. Regardless of format, the questions cluster around the same core domains.
I've seen Nigerian fintechs lose deals not because their security was bad, but because they couldn't articulate it. They had the controls in place but answered the questionnaire poorly — or worse, left fields blank. Let's fix that.
The core question domains
Encryption
Enterprise clients want to know: What encryption do you use at rest and in transit? What key management system do you use? Are encryption keys rotated?
How to answer well: Be specific. Don't just write "AES-256." Write: "All data at rest is encrypted using AES-256 via AWS KMS with automatic key rotation every 365 days. All data in transit uses TLS 1.2+ with HSTS enforced. Database-level encryption is enabled on all RDS instances." Specificity builds confidence. Vagueness triggers follow-up questions and delays.
Access control
Questions will cover: Do you implement role-based access control (RBAC)? How do you manage privileged access? Do you enforce MFA? What's your offboarding process?
How to answer well: Reference your IAM architecture. Describe RBAC implementation, principle of least privilege, MFA enforcement for all administrative access, and your process for revoking access when employees leave. If you use an identity provider like Okta or Auth0, name it. If you conduct periodic access reviews, state the frequency. For guidance on building solid auth, see our authentication security service.
Incident response
Clients want to know: Do you have a documented incident response plan? Who is on your IR team? What are your SLAs for detection and notification? Have you tested the plan?
How to answer well: If you have a documented IR plan, reference it. Include your detection timeline targets, escalation procedures, and client notification commitments (e.g., "We notify affected clients within 72 hours of confirmed breach, in compliance with NDPA requirements"). If you've conducted tabletop exercises, mention them. If you haven't — get one done before you fill this in. See our after-a-breach guide for what a proper IR plan includes.
Compliance and certifications
Questions in this domain: Are you SOC 2 certified? Do you comply with PCI DSS? What about NDPA/NDPR? Have you completed a recent penetration test?
How to answer well: List every relevant certification, audit, and assessment. If you're SOC 2 Type II certified, state the report date and auditor. If you're PCI DSS compliant, state the level and your QSA. If you've completed a penetration test, name the firm, date, and scope. This is where a recent pentest report becomes your most powerful asset.
Build a security evidence library
Create a shared folder with your latest pentest report (executive summary version), SOC 2 report, compliance certifications, security policies, and architecture diagrams. When questionnaires arrive, you pull from this library instead of scrambling. Update it quarterly. This alone can cut your response time from weeks to days.
How a pentest report transforms your answers
A recent penetration test report is the single most impactful document you can attach to a security questionnaire. Here's why:
It answers multiple questions at once. A comprehensive pentest report covers your application security, API security, authentication mechanisms, input validation, session management, and business logic. Instead of writing paragraph-long answers for each domain, you can reference the report: "Our most recent penetration test (conducted by Simpa Labs, May 2026) validated these controls. Executive summary attached."
It provides independent verification. Enterprise risk teams know that self-assessed questionnaires can be aspirational. A third-party pentest report provides independent evidence that your controls actually work — not just that you claim they do.
It demonstrates remediation maturity. A good report shows not just what was found, but what you fixed. If your report includes remediation verification (retest results), it proves you have a vulnerability management process — which is exactly what enterprise clients want to see.

Common mistakes that cost you deals
Leaving fields blank. A blank answer is worse than a negative one. If you don't have a control in place, say so honestly and describe your compensating controls or remediation timeline. "We do not currently have SOC 2 certification but have engaged an auditor for Q3 2026 assessment" is infinitely better than a blank cell.
Being vague. "We use industry-standard encryption" tells the reviewer nothing. They've read 50 questionnaires that week, and vague answers trigger risk flags. Be precise.
Copy-pasting generic policies. Risk teams can spot boilerplate policy documents. Your answers should reflect your actual implementation, not a template you downloaded. If your access control answer references "Windows Active Directory" but you're a cloud-native fintech running on AWS, you've just destroyed your credibility.
Submitting an outdated pentest report. A pentest report from 18 months ago raises more questions than it answers. Enterprise clients expect annual testing at minimum. Keep your security audit schedule current.

Get a pentest reportBuilding a repeatable questionnaire process
If you're fielding multiple enterprise questionnaires per quarter, you need a system. Here's what works:
1. Centralise your answers. Build a master questionnaire response document that covers the 80% of questions that appear in every questionnaire. Update it after every pentest, audit, or policy change.
2. Assign ownership. Your CTO or security lead should own questionnaire responses. Distributing it across random team members leads to inconsistent, contradictory answers.
3. Maintain fresh evidence. Schedule annual penetration tests, keep your ISO 27001 or SOC 2 certifications current, and update your security policies at least annually.
4. Create tiered response packages. Not every client needs the same level of detail. Have a standard package (policies + pentest executive summary) and a detailed package (full report + architecture review + compliance certificates) ready to deploy.
Security questionnaires are sales tools
Reframe how you think about these questionnaires. They're not bureaucratic obstacles — they're your opportunity to differentiate. In a competitive deal where three fintechs offer similar functionality, the one with the strongest security posture wins. A crisp, detailed questionnaire response backed by a recent pentest report, clear compliance certifications, and a mature security programme is a closing argument that competitors without those assets simply cannot match.
