my customer uses a portal that is not yet known, can it be added

Unknown portal appears on the list, recognition to follow

Yes, a portal that is not yet known can be added. Portal recognition is not something that is configured per individual customer: the system learns to recognize a questionnaire format based on the questions and structure it contains, not based on the name of the portal itself. A new portal therefore usually means a new format, and that is added to the recognition as soon as enough users encounter it.

Until then, nothing changes in the core of the process: you upload the questionnaire, and where the system already recognizes a question — even if it comes from an unknown portal — that is filled in from the chain file. Questions that are not yet recognized simply remain open for manual entry, just like any question for which the file does not yet have a source. You confirm each answer with yes or no before it is submitted; that does not change based on which portal it is from. Underlying data such as the company's registration number or the number of employees are recorded portal-independently, so those are proposed anyway as soon as the question is recognized — regardless of which portal that question comes from.

Recognition works at question level, not at portal level

This follows from how the system is set up: it recognizes questions based on wording and context, and links them to the chain file — not to a fixed list of known portals. There is no legal source that applies to this, as this is a technical design choice of the platform, not a legal obligation. However, it remains the case that the source values in the file itself must be based on something, such as the recorded data from the Trade Register Act 2007 for identity questions, or the ten measures of article 21 paragraph 2 of the NIS2 Directive for questions about cybersecurity. Without an underlying source, a field remains open, no matter how well known the portal is.
