2. What Data We Process

We process the following categories of personal data:

  • Account details: name, email address, password (encrypted), organisation name
  • Organisation details: company name, KVK number, VAT number, address, sector, number of employees
  • Assessment data: answers to NIS2 compliance questions, scores, compliance levels
  • Payment details: billing address, subscription type (payment details are processed by Stripe)
  • Usage data: IP address, browser type, page visits, time of access
  • NIS2 assistant questions: questions you ask our NIS2 assistant are processed by OpenAI (via its API; not used to train models) to generate the answer, and are stored for up to 90 days together with a hashed IP address to improve answer quality. Please do not enter personal data in your questions
  • Session recordings: on our public marketing pages (including the free Quick Scan and the NIS2 assistant) we record clicks, scrolling and mouse movements, together with the layout of the page, as session replays and heatmaps. All text on the page and everything you type is masked (Umami's "strict" level), so it is not visible in the recordings. We never record in the logged-in dashboard or the assessment environment. Recording only starts after you give consent via the cookie banner
