How we make this list: we compare pricing pages, product documentation and public user reviews. Rankite is independent; if a vendor ever pays for a featured spot, that listing is clearly labeled Partner.
Key takeaways
- AutoRFP.ai is the most transparent pick on pricing at $899 per month, with cited answers and a Trust Score on every draft, though it is newer than the established library platforms.
- Conveyor pairs questionnaire automation with a trust center that deflects reviews before they arrive, and its free tier makes it the easiest to trial.
- Vanta and Drata make sense when questionnaires are one part of a bigger compliance program, since their answers draw directly from live controls and evidence.
- Loopio and Responsive suit large proposal teams with dedicated content managers, while HyperComply and SafeBase fit leaner teams that want portal autofill and proactive sharing.
Security questionnaires have quietly become one of the most expensive workflows in B2B sales. Vanta reports that the average team now dedicates nearly 12 weeks a year to compliance work, and nearly two-thirds of security professionals say they spend more time proving security than improving it. Every enterprise deal seems to arrive with a spreadsheet of 200 questions you answered last quarter, in a slightly different format, on a slightly different portal.
Security questionnaire software exists to break that cycle. The tools below draft answers from your approved policies and past responses, pull them into buyer portals automatically, route reviews to the right experts, and in some cases deflect the questionnaire entirely with a self-serve trust center. Nine platforms are compared here, from AI-native newcomers to compliance suites where questionnaires are one feature among many.

The best security questionnaire software
#1
AutoRFP.ai
Best for: High-volume questionnaires with cited, defensible answers
Visit autorfp.ai
Starting price$899 per month
Free planFree trial (2-week proof of concept)
AutoRFP.ai takes an accuracy-first stance that stands out in a category full of confident AI drafts. Answers are written only from content your team has already approved, each draft shows the sources behind it, and a Trust Score signals how strongly your sources support the answer. Questions your content cannot back get routed to a human instead of being guessed at. Questionnaires arrive in whatever form they come, multi-tab Excel with macros, Word, PDF, or directly inside procurement portals through the Portal Agent extension, and finished files export back in the buyer's original format.
Pricing is the other differentiator: flat $899 per month on the Scale tier with unlimited users, published openly, which is rare here. The trade-off is maturity. AutoRFP.ai is newer than Loopio or Responsive, so the deepest reporting packs and the longest track records sit elsewhere. For SaaS vendors processing dozens of questionnaires a year who want defensible answers without a permanent content-gardening project, it is the strongest value pick.
What we like- Every answer carries citations and a Trust Score
- Handles Excel, Word, PDF and portals
- Flat pricing with unlimited collaborators
- Self-maintaining library
Watch out for- Newer than library-first incumbents
- Deepest legacy reporting still sits with older platforms
- Scale tier may exceed small-team budgets
Starting priceFree; Pro $9,600 per year
Free planYes
Conveyor attacks the questionnaire problem from both ends. The Trust Center lets buyers self-serve your security documentation, and the Trust Center Agent goes further: a customer uploads their questionnaire and gets back a draft of matched responses with cited sources. For questionnaires that still arrive manually, Conveyor auto-completes them inside buyer portals, including OneTrust and Panorays, pulling answers from your knowledge base instead of copy-paste.
The free tier is genuinely usable, which makes Conveyor the easiest tool on this list to trial, and Pro runs $9,600 per year. The honest catch is scope. Conveyor is a customer-trust platform, not a general RFP suite, so teams that also run complex commercial proposals may need a second tool. And like every AI answer engine here, output quality tracks the quality of the knowledge base you feed it. If deflecting reviews matters as much as answering them, start here.
What we like- Free tier to start
- Trust Center Agent completes portal questionnaires
- AI answers with citations
- Portal autofill across major platforms
Watch out for- Narrower on general RFP work than proposal platforms
- Best results need a well-built knowledge base
- Pro pricing is a jump from free
#3
Vanta
Best for: Compliance teams already running SOC 2 in Vanta
Visit vanta.com
Starting priceSee website
Free planNo (demo only)
Vanta is a trust management platform first and a questionnaire tool second, and that ordering matters. If your company already runs SOC 2, ISO 27001 or HIPAA in Vanta, the Questionnaire Automation feature drafts responses from your actual policies, security evidence and past answers, with citations and confidence scores. The Trust Center shares your posture proactively, and AI agents generate policies and evaluate evidence across the program.
Buy it for that whole program, not for questionnaires alone. As a standalone questionnaire tool it is less deep than the specialists, and pricing is quote-based and sized for compliance budgets. But for teams whose primary need is continuous compliance with questionnaire automation as a secondary workflow, nothing else ties answers to live control data this tightly.
What we like- Questionnaire answers anchored to live policies and evidence
- 400+ integrations
- Trust Center included
- Continuous control monitoring
Watch out for- Questionnaire automation is one feature among many
- Quote-based pricing
- Overkill if you only need questionnaire help
#4
Drata
Best for: Questionnaire answers tied to live compliance controls
Visit drata.com
Starting priceSee website
Free planNo (demo only)
Drata plays a similar hand to Vanta: a continuous compliance platform whose questionnaire automation draws from the same control data that powers your audits. Responses generate from approved Trust Center and knowledge base content, with subject-matter-expert assignment and structured review workflows for the answers that need human eyes. If an auditor asks how an answer was produced, the evidence trail is already there.
The same caveat applies. Bought alone for questionnaires, Drata is expensive and less specialized than Conveyor or AutoRFP.ai. Bought as the compliance system of record, the questionnaire automation becomes a natural extension that keeps answers consistent with what you told your auditor. Shortlist Drata when the compliance program is the project and questionnaires are the symptom.
What we like- AI answers synced to live controls and risks
- Strong audit readiness
- SME assignment and review workflows
- Broad framework coverage
Watch out for- Quote-based pricing
- Questionnaire depth trails the specialists
- Best value inside a full Drata deployment

Free planFree trial
HyperComply is built for the unglamorous reality of questionnaire work: the questions live inside a buyer's portal, and someone has to fill them in. Its Chrome extension detects questions in portals like OneTrust and autofills answers from your knowledge base in real time, syncing results back for a record of past responses. A Trust Page lets you share evidence proactively, and the platform also handles the other direction, sending security reviews to your own vendors.
One fact buyers should know: SecurityScorecard acquired HyperComply in 2025, so the roadmap now sits inside a larger vendor risk platform. It still operates as a standalone product. For lean security and compliance teams that want fast questionnaire completion plus customer-facing evidence sharing without enterprise overhead, it remains a practical pick.
What we like- Chrome extension autofills portals with 90%+ accuracy claims
- Flexible file support
- Trust Page for proactive sharing
- Vendor review side included
Watch out for- Acquired by SecurityScorecard in 2025, roadmap now tied to a parent
- Smaller vendor
- Quote-based pricing
#6
SafeBase
Best for: Proactive trust centers that reduce inbound questionnaires
Visit safebase.com
Starting priceSee website
Free planNo (demo only)
SafeBase's philosophy is that the best questionnaire is the one you never receive. Its trust centers publish your security documentation, certifications and FAQs behind smart access controls, so buyers self-serve instead of sending spreadsheets. When questionnaires do arrive, AI assistance drafts from your trust center content. The platform leans into go-to-market integrations, which is why sales teams tend to like it.
The trade-off is depth on the answering side. If your bottleneck is completing 50 complex questionnaires a month, a dedicated automation tool will move faster. SafeBase wins when the strategy is transparency first: publish proactively, deflect the routine reviews, and answer only what remains. That strategy needs real content investment to work, but for SaaS vendors with a steady deal flow it pays off.
What we like- Strong trust center and buyer transparency tools
- AI questionnaire assistance
- Good GTM integrations
- Widely adopted by SaaS vendors
Watch out for- Questionnaire automation is lighter than the specialists
- Quote-based pricing
- Deflection strategy needs content investment
#7
Loopio
Best for: Large teams with a mature, curated answer library
Visit loopio.com
Starting price$20,000 per year
Free planNo (demo only)
Loopio is the incumbent library platform: a curated, human-maintained answer library with AI-assisted search and Magic autofill, plus project management for the whole response process. Large proposal teams with dedicated content managers have run on it for years, and its review workflows, with multi-step approvals and ownership controls, suit regulated industries.
The model shows its age next to the AI-native tools. Accuracy depends entirely on library freshness, which means someone has to garden the content, and questions the library has never seen return no match. Entry pricing is widely reported around $20,000 per year for Foundations, with higher tiers quote-only and no self-serve trial. Pick Loopio when you have the team to maintain a library and need proven enterprise process. Pick an AI-native tool when you want the system to draft from source documents instead.
What we like- Mature library management
- Magic autofill and project tracking
- Strong collaboration workflows
- Proven at enterprise scale
Watch out for- Accuracy depends on library freshness
- $20,000 per year entry
- Novel questions get no match
- Implementation needs content work
#8
Responsive
Best for: Enterprises needing deep RFP and questionnaire project management
Visit responsive.io
Starting priceSee website
Free planNo (demo only)
Responsive, formerly RFPIO, is the enterprise proposal platform that also answers security questionnaires. Its strengths are operational: assignment tracking, multi-stage review workflows, analytics on response performance, and AI drafting assistance layered over a managed content library. For large financial institutions and enterprises running complex, multi-team responses across RFPs, DDQs and security reviews, that operational depth matters.
Smaller teams will find it heavy. Pricing is quote-based at enterprise levels, the platform rewards dedicated proposal owners, and the content library still needs maintenance. If your world is high-stakes, multi-stakeholder responses with reporting requirements, Responsive is built for exactly that. If your world is 30 security questionnaires a month and a two-person team, the specialists will serve you better.
What we like- Deep workflow automation and analytics
- TRACE scores
- Trust Center capabilities
- Handles complex multi-team responses
Watch out for- Quote-based enterprise pricing
- Can feel complex for smaller teams
- Library upkeep still needs dedicated owners
#9
OneTrust
Best for: Organizations unifying privacy, GRC and vendor risk
Visit onetrust.com
Starting priceSee website
Free planNo (demo only)
OneTrust enters this list from the governance side. Organizations already running OneTrust for privacy management, third-party risk or GRC can handle security questionnaires inside the same platform, with AI-driven risk scoring and workflow automation connecting the questionnaire to the vendor record. For enterprises standardizing on one GRC vendor, that consolidation has real value.
As a questionnaire tool bought on its own merits, it is not the sharpest option here, and pricing sits at the premium end. The platform's complexity also assumes a large team. Shortlist OneTrust when the project is unifying privacy, risk and compliance under one roof. Buy a specialist when the project is answering questionnaires faster.
What we like- Broad GRC and privacy modules
- AI-driven risk scoring
- Strong enterprise footprint
- Questionnaire workflows inside a bigger platform
Watch out for- Premium pricing
- Questionnaire automation is not the core
- Complexity suits large enterprises best
Four things matter more than the marketing. First, intake: questionnaires arrive as Excel, Word, PDF and inside buyer portals, and the best tools handle all four without retyping. Ask for a live demo on your own ugliest spreadsheet, not the vendor's sample.
Second, source grounding. The tools worth buying draft from your approved policies and past answers and show citations. The ones to avoid generate plausible text from general training data. In a security review, a confident wrong answer is worse than no answer.
Third, portal support. A meaningful share of questionnaires now live inside buyer portals like OneTrust, Ariba and Panorays. Autofill inside the portal, with answers synced back to your system, saves more time than any spreadsheet feature.
Fourth, the deflection question. Some tools answer questionnaires; others publish trust centers that stop questionnaires from arriving. Most teams need both, but the right balance depends on your deal volume. High volume favors deflection plus automation; low volume favors a sharp answering tool.
The trust center question: deflect or answer
Every vendor on this list will tell you their AI answers questionnaires faster. Fewer will tell you whether you should be answering them at all. A well-built trust center, with your SOC 2 report, pen test summaries, security FAQs and certifications behind smart access controls, lets buyers self-serve. Conveyor and SafeBase are built around this idea, and teams that do it well report fewer inbound questionnaires, not just faster answers.
Deflection is not free. It needs current documents, someone to maintain them, and a sales team willing to send buyers to the portal instead of forwarding the spreadsheet. And some buyers, especially in regulated industries, will send the questionnaire regardless. The practical setup for most SaaS vendors is a trust center for the routine reviews plus an automation tool for the questionnaires that arrive anyway. Buy the pair that covers both, not just one fast answer engine.
How we chose
We evaluated these platforms against vendor documentation, pricing pages, public reviews on G2 and Capterra, and security questionnaire roundups published in 2026. We did not run hands-on trials. Every tool here exists today and automates security questionnaire responses as a real, current product. We weighted answer accuracy and source grounding, intake format coverage, portal automation, trust center capabilities, pricing transparency and fit for different team sizes, from lean startups to large enterprises.
Frequently asked questions
How much does security questionnaire software cost?
It ranges widely. AutoRFP.ai publishes $899 per month, Conveyor offers a free tier with Pro at $9,600 per year, and Loopio's entry tier is widely reported around $20,000 per year. Vanta, Drata, SafeBase, Responsive, HyperComply and OneTrust are quote-based, usually sized to company size and module mix. Expect enterprise platforms to cost several times the point tools.
Can AI really answer security questionnaires accurately?
It can draft them well when grounded in your approved content. The best tools cite sources and flag low-confidence answers for human review. Accuracy collapses when tools generate from general training data instead of your policies. Plan on human review for anything that goes to a customer, and treat per-answer citations as a requirement, not a nice extra.
What is the difference between a trust center and questionnaire automation?
A trust center publishes your security posture proactively so buyers self-serve instead of asking. Questionnaire automation answers the questionnaires that arrive anyway. They solve opposite ends of the same problem, and most vendors now offer both. SafeBase and Conveyor lead on the trust center side; AutoRFP.ai and HyperComply lead on the answering side.
How long does implementation take?
Point tools like Conveyor or HyperComply can produce first drafts within days of connecting a knowledge base. Library-based platforms like Loopio or Responsive need weeks of content migration and review workflow setup. Compliance suites like Vanta or Drata follow the timeline of the broader compliance program. Ask every vendor for a proof of concept on your own questionnaires before signing.
Do these tools work with buyer portals?
Most do, with varying depth. Conveyor and HyperComply offer autofill directly inside portals like OneTrust and Panorays through browser extensions. AutoRFP.ai handles portals through its Portal Agent. Others focus on file-based questionnaires and export finished documents. If your buyers live in portals, make portal support a knockout criterion in your evaluation.
Should a small team buy questionnaire software?
If you answer more than a few questionnaires a month, yes. The free tier of Conveyor or a trial of HyperComply costs nothing to test, and even a handful of automated responses pays back the setup time. Smaller teams should favor tools with flat transparent pricing and avoid enterprise platforms that assume dedicated proposal staff.
