Best AI Agent for Security Questionnaires: 8 Platforms Compared (2026)

Who has the best AI agent for security questionnaires? For most B2B SaaS teams in 2025 and 2026, the answer is Conveyor, whose agent Sue handles the whole security review from intake to submitted answers and works with any compliance stack. If you already pay for Vanta or Drata, start with the AI built into those platforms before buying anything else, because your answers will come straight from the controls and evidence you already maintain. If nobody on your team has time to review AI drafts, SecurityPal's mix of AI and human analysts is the hands-off option.

That is the short version. The longer version matters because these tools are not interchangeable. Some are compliance platforms with a questionnaire feature, some are standalone agents, some grew out of RFP software, and some put humans in the loop. Prices are almost all quote-based, and several numbers that circulated in older roundups (including earlier versions of this page) no longer match what vendors publish. This guide is current as of October 2026. Every price and stat below is attributed to the vendor or a named third party, and where we could not verify a number, we left it out.

The 8 best AI agents for security questionnaires in 2026

1. Conveyor (Sue) - Best standalone AI agent for security questionnaires

Conveyor is the closest thing to a purpose-built security questionnaire agent. Its AI agent, Sue, became generally available in April 2025, and Conveyor describes her as handling the entire security review: sharing documents from the trust center, answering questionnaires, chasing subject matter experts, and logging changes back into your CRM and ticketing tools. Conveyor later added a second agent, Phil, for RFPs.

On accuracy, Conveyor claims 95 percent or higher first-pass accuracy and a 98 percent questionnaire completion rate. Treat those as vendor numbers. A G2 reviewer quoted on Conveyor's listing put it closer to 85 percent of answers right on the first try, with obscure questions needing a nudge, which is a more realistic expectation for any tool on this list. Conveyor shows a 4.7 rating from more than 150 reviews on G2.

Pricing has changed since earlier write-ups. Conveyor's pricing page now lists a Free plan with 10 trust center credits per month, but it does not include questionnaire automation or integrations. Questionnaire automation sits in the Enterprise plan, which is custom, usage-based pricing with volume discounts. The old flat Pro price that many roundups quote is no longer on the page. Conveyor also has a Chrome browser extension for portals and one-off searches.

Pick Conveyor if questionnaires are a real sales bottleneck and you want the most automation regardless of which compliance platform you use.

2. Vanta - Best if you already run compliance on Vanta

Vanta is a compliance automation platform first, and questionnaire automation is one module of it. The Vanta AI Agent takes the first pass at every answer, routes questions to the right owners, and exports responses back into the original format, whether that was a spreadsheet, a Word document, a PDF or a third-party portal. Vanta says intake can also come through Salesforce, Jira and Slack.

The appeal is that answers draw on the same controls, policies and evidence your SOC 2 or ISO 27001 program already maintains. Vanta claims its AI answers 80 percent or more of security questions automatically and that its answers are accepted up to 95 percent of the time. It also cites an 81 percent faster completion figure from an IDC white paper that Vanta sponsored.

Vanta does not publish prices. Its plans are Essentials, Plus, Professional and Enterprise, all quote-based. The pricing page lists questionnaire automation at 25 questionnaires per year on Plus and 144 per year on Professional, while the questionnaire product page lists 144 per year for standard and 288 for advanced, so confirm your cap in the contract. For budgeting, Vendr's purchase data puts the median Vanta contract at about $20,000 per year across 373 purchases, with a range from $7,500 to roughly $57,000, and estimates that questionnaire automation and Trust Center modules each add $3,000 to $8,000 a year. The larger add-on ranges quoted in some older guides do not match Vendr's current page.

3. Drata (formerly SafeBase) - Best for sales-led trust centers

SafeBase is now Drata. Drata announced a roughly $250 million acquisition of SafeBase in February 2025, and in March 2026 Drata said the SafeBase company brand would be unified into Drata. The products carried on: the Trust Center and AI Questionnaire Assistance are now sold as Drata products, and the marketing site safebase.io redirects to drata.com. Some customer-facing pages and the Chrome extension still carry the SafeBase name.

The strength here is the trust center. SafeBase built its reputation on letting buyers self-serve security documents with rules-based access and NDA gating, which cuts down how many questionnaires arrive in the first place. When one does arrive, AI Questionnaire Assistance drafts answers from your knowledge base, controls, policies and past responses, and you approve, edit or reject each one. Drata says you can pull revenue data in to prioritize reviews by deal status, which is useful when sales and security fight over what to do first.

The SafeBase Chrome extension extracts questions from portal pages, suggests answers in a side panel, and autofills on supported portals. Pricing is not public on any Drata page we checked.

4. SecurityPal - Best if you want humans to do the review

SecurityPal is the managed option. It pairs AI with what it describes as more than 150 full-time certified analysts working from a 24/7 center in Kathmandu. SecurityPal offers three tiers: Basecamp (self-serve software), Summit (AI plus concierge experts) and Everest (fully managed). It markets same-day turnaround for questionnaires and says it has processed more than 3 million questions.

Prices are not published, and the dollar ranges that appear in some roundups are not from SecurityPal. The case for SecurityPal is simple: if your compliance lead is also your IT manager, paying someone else to review the answers is cheaper than having that person do it at night.

5. Responsive - Best when security questionnaires and RFPs share one team

Responsive, formerly RFPIO, is a response management platform that covers RFPs, DDQs and security questionnaires from one content library. It handles Word, Excel and PDF questionnaires and common frameworks such as SIG, VSAQ, CAIQ and NIST 800-171.

Its distinctive feature is the TRACE Score, launched in April 2025, which rates every AI-generated answer on trustworthiness, relevance, accuracy, completeness and explainability so reviewers know where to look first. The Ask feature drafts answers to unusual questions from approved content only. Pricing is quote-based. Choose Responsive if the same people answer sales RFPs and security reviews and you want one system for both.

6. Arphie - Best for traceable, auditable answers

Arphie is an AI-native response platform that shows the sources behind each answer, which matters when a reviewer asks why you said what you said. Arphie says customers switching from legacy RFP or knowledge software see speed and workflow improvements of 60 percent or more, and teams with no prior software see 80 percent or more. It says a switch from another provider usually takes less than a week.

Arphie states it is SOC 2 Type 2 compliant and does not train models on customer data, and it offers zero data retention agreements with model providers for enterprise customers. It also ships an MCP server so teams can query their answer library from Claude or an IDE. Pricing is custom. Earlier versions of this guide quoted an Arphie acceptance-rate figure that no longer appears on Arphie's site, so we removed it.

7. Inventive AI - Best for keeping your answer library clean

Inventive AI sells AI agents for RFPs and security questionnaires. Answers come with source citations and confidence scores, it connects to SharePoint, Google Drive, Confluence and Notion, and it supports Excel, Word, PDF and browser-based questionnaires. The feature that stands out is its AI content manager, which scans your documentation for outdated, duplicated or conflicting answers. Stale answers are the main reason AI drafts go wrong, so this is more useful than it sounds.

Inventive claims more than 95 percent accuracy without publishing its method. We did not find public pricing.

8. 1up - Best for small teams that want published pricing

1up is the rare vendor in this space with prices on its website. Its pricing page lists a Free plan (one admin, 50 answers a month), Starter at $300 per month, Plus at $900 per month and custom Enterprise, with a pay-as-you-go MCP plan as well. The browser extension is included from Starter up. It is lighter than Conveyor or Vanta, but for a startup fielding a few questionnaires a quarter, being able to start without a sales call is worth a lot.

Vendors we considered but did not rank

Loopio is a strong RFP platform that added security questionnaire automation: it detects questions in new documents, suggests answers from your library and exports to the original format. It belongs in the response-management column with Responsive, but it is RFP-first, and we found no recent security-specific AI release, so it sits outside the top eight.

Whistic offers Smart Response, which drafts answers with citations and confidence scores, alongside the Whistic Profile trust center. Whistic leans toward third-party risk management for buyers, and we could not find current 2026 product details, so we left it unranked.

HyperComply combines AI drafting with human review and was acquired by SecurityScorecard in September 2025. It is now being folded into SecurityScorecard's supply chain risk platform, so we would wait to see how the standalone product evolves before recommending it.

AI extensions for security questionnaire platforms

AI extensions for security questionnaire platforms are browser add-ons that read questions directly from a customer's portal page and fill in answers from your approved library, so you never have to export a questionnaire into a separate tool. They matter because a growing share of security reviews arrive through portals such as OneTrust, ServiceNow or a buyer's own procurement system rather than as a spreadsheet.

Four vendors on this list offer one. Conveyor has a Chrome extension for portals and one-off answer lookups. Vanta's Questionnaire Automation extension is still labelled beta in Vanta's help center, which warns that some response types are not supported and must be filled by hand. Drata's SafeBase Chrome extension parses questions from page HTML so it can work on portals without a custom integration, autofills on supported portals and falls back to copy and paste elsewhere. 1up includes its browser extension from the Starter plan.

The practical limits are the same across all of them. Free text, radio buttons and dropdowns usually work. Multi-select checkboxes, file uploads and multi-page portals are where you will still click by hand, and every extension requires an active account on its parent platform. Before you buy, open two or three real portals your customers use and test the extension on them during the trial.

SafeBase vs Vanta

SafeBase vs Vanta comes down to which job matters more. SafeBase, now part of Drata, started as a trust center and questionnaire tool and is strongest at sales-facing trust: gated document sharing, deal-aware prioritization and a portal extension. Vanta started as compliance automation and is strongest at running your SOC 2 or ISO 27001 program, with questionnaire automation and a trust center as modules on top.

If you already use Drata for compliance, the SafeBase products are the natural add-on. If you use Vanta, its own questionnaire module will be cheaper and better connected than bolting on SafeBase. If you use neither and questionnaires are the problem, a standalone agent like Conveyor may be the better buy. We cover this matchup in more depth in our separate SafeBase vs Vanta comparison.

How to choose the right security questionnaire AI

Start with what you already own. If you run compliance on Vanta or Drata, trial the built-in questionnaire AI first. It already knows your controls, and adding a second system means maintaining two answer libraries.

Next, decide who reviews the drafts. Every tool on this list produces first drafts that a person should check before they go to a customer. If you have a security or compliance person with a few hours a week, self-serve software is fine. If you do not, look at SecurityPal or another AI plus human service, and accept the higher price.

Then look at where questionnaires actually come from. Pull your last 20. If most are portals, the browser extension is the feature that matters most, so test it on your customers' real portals. If most are spreadsheets and SIG or CAIQ files, focus on import and export fidelity instead. If the same people also answer RFPs, Responsive or Arphie can cover both.

Finally, ask every vendor three questions and get the answers in writing: how many questionnaires per year your plan includes, whether your data is used to train models, and whether each AI answer shows the source it came from. The questionnaire caps in particular vary a lot between tiers and are easy to miss.

Conclusion

The best AI agent for security questionnaires depends on your stack. Conveyor's Sue is the strongest standalone agent and the default pick for teams that want maximum automation. Vanta and Drata (SafeBase) are the right first stop for their existing customers. SecurityPal is the answer when you want humans to own the work. Responsive and Arphie fit teams that answer RFPs and security reviews together, Inventive AI is worth a look if your answer library is a mess, and 1up is the easiest place for a small team to start with a published price.

Almost every price in this market is quote-based, and vendor accuracy claims are measured by the vendors themselves. Run a trial on a questionnaire you have already answered, compare the drafts to what you actually submitted, and let that decide.
