does supplia log in to our customer's portal to fill in something

No, we never log in

We never log into your customer's portal. That is not a minor caveat but the principle on which Supplia operates: we fill in the questionnaire for you from your supply chain file, you verify each answer with yes or no, and then you submit it yourself to your customer's portal. The login credentials for that portal never come into view with us, and nobody at Supplia needs them.

That applies to every type of portal: a bank asking for the ten measures of Article 21 from the NIS2 Directive, an insurer asking whether you are ISO 9001-certified, or a customer sending out a VSME sustainability questionnaire. In all cases, you upload the list yourself with us, and you submit it yourself to them. We do not sit between you as a party that clicks or sends anything on your behalf.

Why it is set up this way

This follows from how the role distribution in the system is arranged, not from a separate security measure. Supplia is the response side of the chain: we recognize questions, match them to answers from your file, and let you confirm. The submission to the requesting party — the bank, the insurer, the customer translating the CSRD reporting of Directive (EU) 2022/2464 to their suppliers — remains with you. We do not build any connection to third-party portals and therefore do not need login credentials for those portals to do our work. Anyone wanting to verify this looks at what actually happens with data that you enter into Supplia yourself: it remains visible in your own file, for instance where the company's registration number or the number of employees is recorded — never in an external portal to which we would have access.
