Win the security review. Send it back today.
Spend less time answering security questionnaires and more time closing customers. Rendro drafts answers from your documents, shows the source for each, flags gaps for your review, and returns the buyer's own file.
Just your email and company name. We answer from your public pages and return your own file.

The problem
A 200-question spreadsheet stands between you and the signature. Without a security team, it lands on your founders, engineers and sales leads, and pulls them away from the work that grows the business.
- 20–40 hrsfor every questionnaire
- Searching policies, chasing engineers and rewriting answers you have given before. (Industry estimates for completing one by hand.)
- Daysof a stalled deal
- Procurement won't move until security signs off. Every day the questionnaire sits unanswered, momentum and buyer attention fade.
- 250cells to paste by hand
- A chatbot can draft text, but someone still has to place every answer in the right cell, choose the right dropdown value and keep the workbook intact.
How it works
From blank questionnaire to finished file in three steps.
Set up your knowledge base once. After that, each questionnaire takes minutes to draft and an hour or two to review.
01
Add your documentation.
Upload your policies, your SOC 2 report if you have one, and past questionnaires. Rendro answers only from this material.
Information Security Policy.pdfReadyAccess Control Policy.docxReadySOC 2 bridge letter.pdfIndexed02
Upload the questionnaire.
Add the file exactly as your prospect sent it. Rendro maps the questions and answer columns on every tab and drafts each answer with its source.
Acme_Security_Review.xlsx118 questions found on 3 sheets
03
Review, approve, return.
Approve, edit or assign each answer, then download the original file, completed and ready to send. Approved answers are saved for future questionnaires.
Do you encrypt data in transit?
Yes. All traffic uses TLS 1.2 or higher.
Encryption Policy §3ApproveEdit
What they sent. What you send back.
Not a new document: the buyer's own spreadsheet, with its formatting, dropdowns and layout intact, completed.
Tabs, dropdown lists, merged cells, hidden columns, colours and formulas are preserved. Rendro only writes into the answer cells.

Accuracy
Internal test results. Transparent gaps.
- of answerable questions answered correctly
- 96%of answerable questions answered correctly
- of unanswerable questions flagged for your review
- 100%of unanswerable questions flagged for your review
- unsupported facts or certifications in the internal test
- 0unsupported facts or certifications in the internal test
Results from Rendro's internal test of 60 questions about a fictional company, on one run. Answers were checked against that company's documents. Your results depend on your own documents. AI drafts can contain mistakes, so you review and approve every answer before export.
Trust
Verified, not just promised. Check it yourself.
You're trusting us with sensitive documentation, so we publish the evidence: independent scans of our site you can re-run, our security policies, our providers' audits, and what isn't in place yet.

Rendro never trains models on your data. Under Anthropic's commercial terms, data sent through its API isn't used to train its models by default.
Sourced. Never invented.
Rendro answers only from what you upload. When it can't find support, it tells you instead of guessing.

Why Rendro
Built for accuracy, not just speed.
Drafting an answer is the easy part. Getting it right, delivering it in the buyer's format and staying consistent across every review is what wins deals.
Every answer shows its source.
Each answer cites the document and section it came from, with the passage one click away. Verify it in seconds and stand behind it on a call with the buyer's security team.
Example answers for a fictional company, not Rendro's own.

More than security questionnaires
Every form buyers send. One answer library.
Security questionnaires, RFPs, due-diligence questionnaires and vendor onboarding forms all ask about the same company. Approve an answer once and Rendro reuses it everywhere, in the style each form needs.
Rendro vs. general-purpose AI
Chatbots draft text. Rendro delivers the finished questionnaire.
ChatGPT writes fluent text. The work that matters is everything around it: the buyer's file, a source for each claim, and a consistent position across every customer.

What kinds of questionnaires does Rendro handle?
Security questionnaires, RFPs, due-diligence questionnaires and vendor onboarding forms, as Excel (.xlsx), CSV, Word (.docx) or PDF files. Excel, CSV and Word files come back with the answers written into the original (tabs, dropdowns, merged cells and formatting intact); a PDF comes back as an answer sheet in the same order. You choose the kind of form when you upload it, and Rendro writes in the style it needs. Questionnaires inside online portals are on the roadmap.
Do we need to be a software company?
No. Rendro answers about whatever your company actually does, from your own documents: software, IT and managed services, agencies, consultancies, fintech or healthcare suppliers. If buyers send you questionnaires, it's for you.
Will it make things up?
No. Rendro only answers from the documents and past answers you give it, and shows the source for each one. When nothing supports an answer, it says so and marks the question for your review instead of guessing.
We don't have SOC 2. Can we still use Rendro?
Yes. Many growing companies don't yet. Rendro answers from your policies, past questionnaires and company facts, and clearly flags the questions where you have no supporting evidence yet.
How is this different from pasting it into ChatGPT?
A chatbot gives you text. Rendro gives you their spreadsheet back, filled in, with a source for every answer, the unsupported ones flagged, and the same wording every time thanks to your answer library.
Is our data used to train AI models?
No. Rendro never trains models on your data, and under Anthropic's commercial terms, data sent through its API isn't used to train its models by default. Each company's data is isolated in our database.
Do reviewers cost extra?
Never. Invite as many engineers, lawyers and executives as you need to review answers. Rendro charges by questionnaire, not by seat: on every paid plan your whole team can edit too.
What happens when my trial ends?
Your workspace moves to the Free plan. Nothing is deleted or locked, so your documents and answer library are waiting when the next questionnaire arrives.
Can I cancel anytime?
Yes. Plans are month to month, with no annual contract required. Yearly billing is optional and saves you two months.
