Teaser only. This is not the full article. Complete Article 21 DNS control mapping and evidence guide: NIS2 Article 21: DNS Auditors Ask For
Article 21 talks about technical and organizational measures. Your assessor talks about _dmarc, MTA-STS, and who can edit Cloudflare.
EU auditors translate transmission security into queryable DNS objects: SPF, DKIM, enforced DMARC, transport records, and proof you monitored changes between visits. A policy binder without TXT records fails the conversation fast.
Verify what they will query on day one:
dig _dmarc.example.com TXT +short
dig _mta-sts.example.com TXT +short
If p=none is live and nobody reviews rua= XML, you have a gap even when "email security" is checked on a spreadsheet.
