Security questionnaires and DDQs
What is the best RFP software for security questionnaires?
Short answer
14 response tools in this directory treat security questionnaires as a core job: Inventive AI, Conveyor, Iris, SiftHub, Skypher, Wolfia and 8 more. Pick by where your questionnaires arrive: named SIG or CAIQ files favour the tools that document those formats, buyer portals favour a browser extension, and a big existing library favours the library-first suites.

Why this question matters
A security questionnaire is a list of commitments about encryption, access, incident response and subprocessors. The work is less about writing and more about matching each question to current, approved evidence. That is why the tools below are judged on what they document about questionnaire handling, not on general RFP drafting.
Which one fits your situation
- If you mostly receive standard SIG or CAIQ files, start with Inventive AI, Conveyor and Iris.
- If you answer inside buyer risk portals, start with Inventive AI, Conveyor and Iris.
- If you already run a large, governed answer library, start with SecurityPal, Loopio and Ombud.
What to test in a trial
- Send each vendor the same real questionnaire, including one question your current evidence cannot support.
- Check whether the unsupported question is flagged for a person or filled with plausible text.
- Swap in a newer policy and see which previously approved answers get marked for review.
- Return the file in the buyer format and count the cells you had to fix by hand.
Caveats
- A core capability score says the product is built for this job. It does not prove it parses your exact template version.
- Certifications held by the vendor say nothing about the accuracy of the answers it drafts for you.
How we decided who qualifies
Only RFP, DDQ and questionnaire response tools with a published profile are checked. A tool is named here only when its record shows the rule above, either in a sourced research fact or in the reviewed profile, and we publish an answer only when at least three tools qualify. A tool missing from the table may still do this; it has not been documented in a way we could source. Read the research methodology for how facts are dated and corrected.
More questions on this topic
Is security questionnaire software different from RFP software?
Often the same product covers both. The difference is the evidence: security answers must match current policies and audit reports, so source visibility and reviewer routing matter more than prose quality.
Do I need a trust center as well?
Not always. A trust center deflects some questionnaires before they arrive. The questionnaire tool handles the ones that still come in, ideally reading from the same approved evidence.
How many questionnaires justify a dedicated tool?
Count hours, not files. If the same engineers keep answering the same control questions every month, reuse with review pays back faster than the questionnaire count suggests.
