Your security team shouldn't be writing the same due diligence questionnaire answer for the fifteenth time.

Every due diligence questionnaire is 10–40 hours your security team won't get back.

When a 300-question security questionnaire lands in your inbox, someone senior has to open it. Then they dig through SOC 2 reports, privacy policies, prior questionnaire responses, and a half-remembered Slack thread from Q3. Then they copy-paste. Then they pray they got the right version. Meanwhile the deal sits frozen in the prospect's vendor-review queue, watching a competitor move faster.

Answered from your live security 
program, not a playbook.

Cyberbase's Context Engine indexes your actual policies, certifications, and every prior questionnaire response, then answers new due diligence questionnaires from the current source of truth. Every answer cites the exact document it came from. Your team reviews the output. They don't rewrite it from scratch. Questionnaires that used to eat a week land in the prospect's inbox the same day.

From inbox to sent in three steps

Upload the questionnaire

Drop any due diligence questionnaire: Excel, Word, PDF, or a shared vendor portal link. Cyberbase reads the structure natively: free-text fields, yes/no grids, scored matrices, conditional branches. No reformatting. No template mapping.

Context Engine Answers

Every question gets matched against your live policies, SOC 2 and ISO 27001 evidence, DPA commitments, and every prior answered questionnaire. Cyberbase drafts the response, attaches source references, and flags anything it can't answer with confidence.

Review, edit, send

Responses come back in the original file format, ready for your team to review, not rewrite. Accept, edit, or bounce flagged items to a subject-matter expert. What used to take a week goes back the same day.

The only due diligence questionnaire platform that also redlines your contracts and powers your Trust Center, from one Context Engine.

Sourced answers, never hallucinated.

The Context Engine cites the exact policy, 
SOC 2 control, or prior questionnaire response behind every answer. Auditors and prospects get traceability on demand. No hallucinations. Not now, not ever.

One platform. Three products. One brain.

Due diligence questionnaire automation, contract redlining, and a free-forever Trust Portal: all powered by the same Context Engine. The answer you give in a due diligence questionnaire matches the DPA you sign two weeks later. No competitor has all three.

No throttling. No credits. No caps.

Vanta caps at 25–144 questionnaires/year 
by tier. Conveyor runs on credits. Cyberbase handles 250+ per month with no add-ons, no per-seat charges, and no surprise overages when procurement season hits.

Frequently asked questions

What is due diligence questionnaire automation?

Due diligence questionnaires, the security and compliance forms vendors fill out during procurement, fundraising, or partnership reviews, usually take a team ten to forty hours each. The work is mostly digging: pulling answers from old questionnaires, policies, and audit reports to respond to dozens of overlapping questions. Cyberbase shortcuts all of that. Context Engine indexes your security policies, compliance certifications, previous questionnaire responses, and operational records. When a new questionnaire lands, the AI finds the right source material for each question and drafts an accurate answer with a citation back to where it came from. Excel and PDF formats are both supported. Answers that used to take a week show up in minutes, and every one of them is traceable.

What's the best due diligence questionnaire automation software in 2026?

The best due diligence questionnaire automation software depends on what else you need to do. Conveyor leads on AI accuracy for pure questionnaire response. SafeBase (Drata) leads on Trust Portal-driven deflection. Vanta leads if you also need full SOC 2 / ISO 27001 automation. Cyberbase leads if you want all three workflows in one platform: due diligence questionnaire automation, a free-forever Trust Portal, and AI contract redlining, running on a single Context Engine that shares knowledge across them. No competitor unifies the three.

How fast can Cyberbase answer a due diligence questionnaire?

A 300-question due diligence questionnaire goes from inbox to draft response in minutes, not days. Your team then reviews the output rather than writing it from scratch, typically an hour of review for what used to be a week of writing. Augment Code used Cyberbase to auto-answer 8,356 due diligence questionnaire questions in their first six months.

How much does due diligence questionnaire automation software cost?

Standalone due diligence questionnaire automation tools typically cost $8,000–$25,000+ per year (Conveyor's public Professional plan is $9,600/yr). Layering in a Trust Portal, security questionnaire automation, and contract redlining from separate vendors brings most Series A–C SaaS teams to $22,000–$65,000+ annually. Cyberbase replaces that fragmented stack with one platform, with the Trust Portal free forever and due diligence questionnaire automation included in every paid plan.

What's the difference between a due diligence questionnaire and a security questionnaire?

A security questionnaire is a subset of a due diligence questionnaire. A due diligence questionnaire is a broad assessment covering security, operations, financials, and compliance. A security questionnaire focuses specifically on data handling, infrastructure security, and regulatory compliance. In practice, the lines blur: a 300-question "security questionnaire" from an enterprise prospect often covers everything a due diligence questionnaire would. Cyberbase handles both from the same indexed knowledge base.

What file formats does Cyberbase support for due diligence questionnaires?

Cyberbase ingests due diligence questionnaires in Excel (.xlsx), Word (.docx), and PDF. Answers are returned in the original file format, preserving the sheet structure, question order, and formatting your prospect or investor expects. Teams don't have to reformat, re-paste, or translate anything back into the requester's template.

What is the Context Engine, and why does it matter for due diligence questionnaires?

Context Engine is Cyberbase AI's continuously-updated knowledge layer: a dynamic internal brain that indexes your security policies, SOC 2 and ISO 27001 evidence, completed questionnaires, signed contracts, and DPA commitments, and keeps the links between them live. Because it learns from every finished questionnaire, redlined contract, and resolved due diligence questionnaire, the corporate memory gets sharper over time. Every new due diligence questionnaire is faster and more accurate than the last, the opposite of static Q&A libraries that rot the moment your policies change.

How is Cyberbase different from Conveyor, Loopio, or Vanta Questionnaire Automation?

Most due diligence questionnaire tools are Q&A libraries you maintain manually. Someone has to remember to update the library every time a policy changes. Cyberbase is different in three ways. First, Context Engine stays live: when a policy updates, every future answer reflects it without manual re-entry. Second, Cyberbase handles the full due diligence questionnaire spectrum: customer security reviews, investor due diligence questionnaires, financial due diligence, and vendor risk assessments, from the same knowledge base. Third, Cyberbase doesn't cap usage: Vanta caps at 25–144 questionnaires/year by tier, Conveyor runs on credits, and Cyberbase handles 250+ per month with no throttling.

What kinds of due diligence questionnaires does Cyberbase handle?

Customer security reviews, investor due diligence (pre-funding and post-funding), financial due diligence questionnaires, vendor risk assessments, AI governance questionnaires (increasingly common since ISO 42001), and standard frameworks like SIG, CAIQ, and HECVAT. For Series A–C SaaS companies selling to enterprise, the ones managing customer security reviews and investor diligence simultaneously, answering all of them from a single indexed knowledge base is where the real time savings compound.

How does Cyberbase handle questions it can't confidently answer?

Rather than guessing, Cyberbase flags any question that can't be answered confidently from your current documentation and routes it to your team for manual response. Each flagged question is surfaced as a potential policy gap, so answering due diligence questionnaires also becomes a continuous audit of where your documentation is thin. Most platforms fabricate around gaps. Cyberbase makes them visible.

Is due diligence questionnaire automation included in every Cyberbase plan?

Yes. Every Cyberbase plan includes due diligence questionnaire automation alongside the Trust Center, security questionnaire responses, and contract redlining, no add-on fees, no per-questionnaire charges, no usage caps. Replacing a fragmented stack of dedicated due diligence questionnaire tools, trust centers, and contract review services typically saves Series A–C SaaS companies $22,000–$65,000+ per year.

What ROI can I expect from Cyberbase due diligence questionnaire automation?

Augment Code, a Cyberbase customer, recovered 743 hours of team time and $185,750 in staff work within six months for a platform spend of $14,394: a 13:1 return. That work included 8,356 due diligence questionnaire questions answered automatically and 155 contracts reviewed. The more security assessments, due diligence questionnaires, and contracts your team handles, the more the math compounds in your favor.

How does Cyberbase automate security questionnaire responses?

Context Engine keeps an indexed copy of your security policies, SOC 2 reports, certifications, and prior questionnaire responses, refreshed as your documents change. When a new questionnaire shows up, the AI matches each question to the best source across all of that and drafts a complete, cited answer for your team to review. Template-based tools fall over when your policies evolve. Cyberbase doesn't, because it pulls from live source material and cross-checks multiple sources for consistency. When a question can't be answered confidently from what's already indexed, it gets flagged as a policy gap and routed to your security team to handle manually. Excel and PDF questionnaires are both supported, and most responses land in minutes.

Your next due diligence questionnaire doesn't have to eat the week

Security questionnaires shouldn't be the thing that slows your pipeline. Cyberbase AI answers them in minutes from your live security program: sourced, traceable, and returned in the original file format.
