Best AI Agent for Security Questionnaires: 6 Platforms Compared (2026)

The best AI agent for security questionnaires can turn a 4-to-6 week slog into a same-day task. I know this because we recently helped a 30-person SaaS company evaluate six of the top platforms, and the difference between manual and automated was not incremental. Their security team went from spending 60 percent of their week on vendor questionnaires to handling the same volume in a few hours. The catch is that not every tool works the same way, and the one that fits your team depends on whether you want software, a managed service, or something in between.

We tested and compared six platforms on the metrics that actually matter: real pricing, first-pass accuracy, setup time, and which compliance frameworks they support. This guide is for agency owners, IT leads, and operations people who are tired of losing deals because security reviews take too long. If you have been burned by a tool that looked great in a demo but choked on a 300-question SIG questionnaire, this is for you.

The 6 best AI agents for security questionnaires in 2026

1. Conveyor - Best for teams that want self-serve automation on a budget

Conveyor is the platform I recommend first to anyone spending under $10,000 per year on security questionnaire tooling. The Pro plan runs $9,600 annually, and there is a free tier with 10 credits per month if you want to test before committing. Each credit covers one organization with unlimited users, so even the free plan is usable for low-volume teams.

The numbers are strong. Conveyor claims 95 percent or higher first-pass accuracy and says teams see a 91 percent decrease in time spent on questionnaires. It handles SOC 2, RFPs, and trust center requests out of the box, supports more than 50 languages, and includes a browser extension so your team does not need to learn a new interface.

What makes Conveyor stand out at this price point is the combination of a generous free tier and production-grade accuracy. Most competitors either charge $15,000 or more for similar accuracy or offer a free plan so limited it is essentially a demo. Conveyor's free tier actually lets you process real questionnaires and decide if the paid plan is worth it.

2. Vanta - Best for compliance-first organizations

Vanta built its reputation as a compliance automation platform and extended that into security questionnaires. The Core plan starts around $10,000 per year, but questionnaire automation is an add-on costing $10,000 to $25,000 annually on top of the base. The median Vanta subscriber spends about $19,800 per year overall.

That is not cheap, but you are getting more than a questionnaire filler. Vanta routes questions to the right subject matter experts automatically, sends reminders, and returns answers in whatever format the vendor sent them: spreadsheet, document, or third-party portal. If your organization is already building a compliance program around SOC 2 or ISO 27001, Vanta fits into that ecosystem rather than sitting alongside it.

The add-on pricing can stack up. Trust Center support starts at $6,000 per year and Vendor Risk Management runs $11,200 annually. For a mid-size company that needs the full suite, you are looking at $25,000 to $40,000 per year. That makes sense for teams managing 50 or more questionnaires per quarter, but it is overkill for a 20-person startup fielding a handful of vendor reviews each month.

3. SecurityPal - Best for teams that want a fully managed service

SecurityPal is not a software platform in the traditional sense. It is a managed service that combines AI with over 150 certified human analysts. You submit your questionnaire, and their team fills it out using a mix of automation and expert review. The guaranteed turnaround is 12 hours, and they have answered more than 2 million questions to date.

This model reduces typical completion times from 4 to 6 weeks down to several days. The analysts are multilingual, certified in cybersecurity, and operate without outsourcing. Pricing is not public, but estimates from buyer reports range from $5,000 to $50,000 per year depending on volume and complexity.

SecurityPal works best for teams that do not have dedicated security staff to review AI-generated answers. If your compliance person is also your IT manager and your office administrator, handing off questionnaires entirely makes more financial sense than paying for software your team will not have time to operate. The tradeoff is cost: managed services are always more expensive than self-serve, but the total cost of ownership is often lower when you factor in the hours your people would spend reviewing and editing AI output.

4. SafeBase by Drata - Best for sales teams prioritizing by deal size

SafeBase, now part of Drata after their acquisition, operates as a Chrome extension that works directly inside TPRM portals, Google Forms, and Google Sheets. Instead of exporting questionnaires into a separate tool, you fill them out where they live. The AI pulls answers from your trust center, knowledge base, and uploaded documentation.

Teams report 80 percent or greater time savings. But the feature that sets SafeBase apart is revenue-based prioritization. You can pull deal data into the platform and sort incoming questionnaires by associated revenue, so your team works on the $500,000 deal before the $10,000 one. For sales-focused agencies and companies where security reviews are a bottleneck in the sales pipeline, that prioritization alone can change close rates.

The Drata acquisition means SafeBase is now part of a broader compliance platform. If you are already using Drata for SOC 2 automation, adding SafeBase is a natural extension. Pricing is not publicly listed, so you will need to contact their team for a quote.

5. Arphie - Best for transparency and auditability

Arphie was founded in 2023 and uses a patented AI architecture that shows the exact source, confidence level, and reasoning behind every generated answer. That transparency matters in regulated industries where you need to explain not just what you answered but why. The platform reports an 84 percent acceptance rate on AI-generated answers, meaning your team approves 84 out of 100 responses without editing.

ComplyAdvantage reported a 50 percent time reduction after implementing Arphie, and the platform deploys within one week through direct integration with existing knowledge sources. Users switching from legacy RFP software see 60 percent or greater improvement, while teams with no prior tooling see 80 percent or greater gains.

Arphie is SOC 2 Type 2 compliant and does not use customer data to train its models. For healthcare companies or legal teams where data handling matters, those guarantees carry weight. Custom pricing means you will need to talk to their sales team, but the one-week deployment makes it easy to pilot before signing a contract.

6. Responsive - Best for multi-framework compliance

Responsive stands out for the sheer number of compliance frameworks it supports natively. SIG, VSAQ, CAIQ, VSA, NIST 800-171, and CIS Controls are all covered out of the box. If your organization fields questionnaires across multiple regulatory environments, Responsive handles the format switching that other platforms struggle with.

The platform includes a TRACE Score for every AI-generated response, giving your reviewers a confidence metric before they approve or edit. The Ask feature generates custom answers for complex or unfamiliar questions, drawing only from approved content. Responsive also surfaces outdated content that might need refreshing, which prevents your team from submitting answers based on last year's security policies.

For local businesses managing compliance across state and federal standards, or agencies handling questionnaires for multiple clients, Responsive's framework breadth is hard to match. Pricing is custom but the platform is built for teams that handle high questionnaire volume across varied formats.

How to choose the right security questionnaire AI

The first decision is whether you want self-serve software or a managed service. Self-serve tools like Conveyor, SafeBase, and Responsive cost less but require your team to review AI output before submission. Managed services like SecurityPal cost more but handle the entire process. If your team has fewer than 5 people and no dedicated security role, a managed service will likely save you money in total hours even though the sticker price is higher.

Budget is the next filter. Under $10,000 per year, Conveyor is the clear choice. Between $10,000 and $25,000, you are choosing between Vanta's compliance integration and Arphie's transparency features. Above $25,000, SecurityPal's managed model and Vanta's full suite both become viable depending on whether you want hands-on or hands-off.

Finally, match the tool to your primary use case. If you manage multiple frameworks, pick Responsive. If you need to prioritize by deal value, pick SafeBase. If auditability is non-negotiable, pick Arphie. If you want one platform for compliance and questionnaires together, pick Vanta. There is no single best option, but there is a best option for your specific situation.

Conclusion

For budget-conscious teams, Conveyor delivers the strongest value at $9,600 per year with 95 percent accuracy and a free tier to test. Enterprise teams already invested in compliance platforms should evaluate Vanta for its deep integration with SOC 2 and ISO 27001 workflows. Teams that want zero internal review overhead should look at SecurityPal's managed service model. Sales-driven organizations should evaluate SafeBase for deal-size prioritization. Security teams in regulated industries should test Arphie for its source citation and auditability features. And teams juggling multiple compliance frameworks will find the most coverage with Responsive.
