How to Answer a Security Questionnaire in English

A security questionnaire — sent by a prospective customer’s procurement or security team before they’ll sign a contract — is a genre with its own conventions. The reviewer is often non-technical or semi-technical, comparing your answers against a checklist, and imprecise language (“we take security seriously”) reads as evasive. This guide covers the English phrasing for answering clearly, accurately, and without overstating your posture.

Answering “Yes” Precisely

Even a confident “yes” benefits from a specific, verifiable detail rather than a bare affirmation.

• “Yes. All data is encrypted at rest using AES-256 and in transit using TLS 1.2 or higher.”
• “Yes, we perform an annual third-party penetration test; the most recent report is available under NDA on request.”
• “Yes — access to production systems requires SSO with mandatory multi-factor authentication for all employees.”

Answering “Partially” Honestly

Most real answers aren’t a clean yes or no — the skill is describing the gap precisely instead of rounding up to “yes” or hedging into vagueness.

• “Partially. We encrypt all customer data at rest, but backups stored in cold storage are currently encrypted with a shared key rather than per-tenant keys; per-tenant encryption for backups is on our roadmap for Q3.”
• “We have this in place for our production environment, but our staging environment does not yet enforce the same access control policy — staging contains no customer data, so the risk is limited to internal test data.”
• “This control exists for new employees onboarded after January of this year; we’re in the process of extending it retroactively to the full existing team.”

Answering “No” Without Sounding Evasive

Saying no directly, with context, builds more trust than a vague deflection.

• “No, we do not currently hold a SOC 2 Type II report. We are in the readiness phase and expect to complete our first audit within the next two quarters.”
• “No — we don’t offer customer-managed encryption keys at this time. This is a frequently requested feature and is on our public roadmap.”
• “This control is not applicable to our architecture, since we do not store payment card data directly; all payment processing is handled by [PCI-compliant processor], and we can provide their attestation of compliance.”

Flagging Ambiguous Questions

Security questionnaires sometimes contain vague or ambiguous questions — ask for clarification rather than guessing.

• “Could you clarify what’s meant by ‘regular’ vulnerability scanning here — are you asking about frequency, or about the specific tooling used?”
• “This question seems to assume an on-premises deployment model; since we’re fully cloud-hosted, could you confirm which sections apply to our architecture?”

Pointing to Evidence

Where possible, back claims with a reference to a concrete artifact rather than asking the reviewer to take your word for it.

• “This is documented in our security whitepaper, section 4, which I’ve attached — happy to walk through it on a call if useful.”
• “Our current SOC 2 Type II report covers this control directly under CC6.1; I can share the relevant excerpt.”
• “We maintain a public status page and a subprocessor list, both linked here, which cover the transparency requirements in this section.”

Key Takeaways

• Back every “yes” with a specific, verifiable detail — a bare affirmation reads as unconvincing to security reviewers.
• Describe partial compliance precisely, including the gap and the timeline to close it, rather than rounding up or hedging vaguely.
• Answer “no” directly with context and a roadmap where relevant — it builds more trust than evasive language.
• Ask for clarification on ambiguous questions rather than guessing at intent.
• Point to concrete evidence (reports, whitepapers, attestations) wherever possible instead of asking for blind trust.
