RFPs, DDQs & security questionnaires, explained
Practical guides to how these processes work, the frameworks behind them, and how to respond faster without sacrificing accuracy.
How to respond to security questionnaires faster
A security questionnaire is a structured set of questions a customer's security or procurement team sends to check how you protect their data before they buy. The way to answer them faster is to stop starting from scratch: keep your approved answers in one reusable library, map them to the common frameworks like SIG and CAIQ, and verify each reused answer against its source before it goes out.

A due-diligence questionnaire (DDQ) is a structured document one organisation sends another to evaluate it before a deal, investment, or partnership. It gathers standardised information on operations, finances, security, compliance, and risk, so the requester can make an informed decision and document why they trusted the other party.

An RFP (request for proposal) response is a structured reply to a buyer's formal request that shows how your product meets their requirements, terms, and pricing. A repeatable process, from a clear bid or no-bid decision through drafting against a content library to a reviewed, on-time submission, lets a small team win more bids without adding headcount.

SIG, CAIQ, and VSAQ are the three standard security questionnaires you are most likely to be handed. SIG is the broad, all-industries one, CAIQ is the cloud-specific one, and VSAQ is the lighter, engineer-friendly one. They overlap a lot, so a single well-written answer can usually satisfy all three if you map it carefully.

Third-party risk management (TPRM) is how an organisation assesses and keeps an eye on the outside vendors it depends on, so that a supplier's weakness does not quietly become its own. It usually runs as a lifecycle: screen a vendor before onboarding, assess them with questionnaires and evidence, set the right contract terms, and then re-check them on a schedule.
