can I see afterwards who confirmed a particular answer

Who confirmed which answer is recorded per answer

Yes, you can see that. Every confirmation — the click on "yes" or "no" for a proposed answer — is recorded with who gave that confirmation and at what time. That applies per answer, not per list: if three colleagues work on the same questionnaire, you can afterwards see who handled which part. That is not an extra function you need to enable; it is how confirming works.

This is especially relevant for answers that recur frequently, such as the number of employees or whether there is liability insurance: someone fills that in once for the supply chain file, and that confirmation is then reused in dozens of lists. If a client later asks why a particular answer was filled in that way, you can trace back who last confirmed it and when. We do not read those lists and do not assess them — the confirmation is and remains an action of the entrepreneur themselves, we only record who and when.

Where this follows from: the supply chain file records the confirmer

This does not follow from a law or standard, but from how the platform is built: every answer in the supply chain file has a status "proposed" or "confirmed", and "confirmed" comes with a name and a timestamp. That mechanism is separate from the underlying sources — whether an answer concerns the company's registration number, ISO 27001 measures or the ten measures of article 21 paragraph 2 of the NIS2 Directive, the recording of who confirmed works the same way everywhere. Who exactly may confirm and whether that role can be changed is a setting within your own organisation on the platform, not something that follows from an external regulation.
