NIS2FillAnswer security questionnaires once. Reuse them forever.
NIS2Fill is a web application that helps suppliers answer the security questionnaires their customers send them. Upload the security documents you already have, and every questionnaire a customer sends you starts mostly answered.
No blank form, no setup call. Two uploads and a score.
NIS2Fill needs to know what you already know and what you're being asked now.
Upload what you know
Add existing policies, completed questionnaires, or a handful of answers. This becomes your answer library.
Upload the questionnaire
Drop in the file your customer sent. NIS2Fill matches every question against your library and shows your coverage score immediately.
Sign up to reveal your answers
Create your account and choose a plan to unlock every matched answer, fill the remaining gaps, and export the finished file.
Built around the questionnaire, not a generic form builder
Fills the actual file
Excel and Word questionnaires are filled in place, with dropdowns, formulas, and formatting kept intact.
Answers you can stand behind
Every answer traces back to a document you uploaded or wording you approved. Nothing is invented for you.
Red-flag before you submit
Answers that wouldn't hold up under a NIS2 audit are flagged before they go out, not after.
EU-hosted, org-isolated
Your data lives in the EU with row-level security enforcing isolation between every organization.
Works in your language
Draft and answer in English or Dutch today, matching the language the question was asked in.
A gap list, not a blank form
Questions your library can't answer yet become one short list. Each answer you add is saved back for next time.
NIS2 made security questionnaires everyone's problem, not just big enterprises'.
Directive (EU) 2022/2555 requires every regulated company to manage risk in its own supply chain. In practice, that means your customer pushes a security questionnaire down onto you, even if NIS2 never applies to your company directly.
The first questionnaire is work. Every one after it is not.
A 60-question supplier questionnaire takes a small team 6-10 hours the first time. The second one takes twenty minutes, because you already answered it.
It compounds
Your answer library is yours and it only grows. Every gap you fill is filled forever.
Less time, fewer mistakes
You save hours on every questionnaire, and reusing answers you already approved lowers the risk of sending a wrong one.
They are your words
We never put words in your mouth - every answer is one you wrote and approved.
Answer once. Then pay for how often you need it.
Prices exclude BTW. Checking what we can already answer is free - no card needed.
Before you upload anything
Is this only for NIS2 questionnaires?
No. NIS2Fill matches the questions in whatever you upload against your own answer library, so it isn't limited to NIS2 wording or a fixed template. Your library starts organized around the categories NIS2 Article 21(2) covers, since that's the most common starting point for our users, and every answer you add extends it to whatever your customers actually ask.
Where is our data stored?
In the EU (Supabase, EU region), with row-level security enforcing isolation between every organization on the platform.
Do you keep our questionnaire answers?
Yes, that is the point. Every answer you approve is saved to your private answer library, so the next questionnaire starts more complete than the last.
Do I need a company email to sign up?
No. Sign in with any Google or Microsoft account. Once you're subscribed you can invite teammates from inside the app.
Stop answering the same questionnaire twice.
It takes two files: one you have already answered, and the blank one you need filled in. A coverage score in about a minute.
