We welcome current industry initiatives to develop a unified questionnaire catalogue for suppliers."

BSI NIS-2 FAQ (supply chain and security).

This supplier portal IS that industry initiative. A privately built, unified questionnaire catalogue, structured by the canonical EU taxonomy (ENISA TIG §5) so every NIS 2 regulated entity can satisfy CIR §5.1.4 from a single source.

Bilateral and private.

Built in Germany, hosted in the EU, aligned with BSI Grundschutz. Your data is shared only with customers you explicitly invite. No public URL, no search-engine indexing.

Start in two minutes.

Sign in with Google. Enter company name and primary domain. Fill the questionnaire at your own pace. When you are ready, invite your customers.
