VS-NfD is handled the way VS-NfD should be: in a closed briefing

VS-NfD — Verschlusssache, Nur für den Dienstgebrauch — is Germany's restricted classification level. Processing classified material carries requirements for approved products, procedures and environments that go beyond what any public compliance page can, or should, discuss.

We publish no architecture, requirement mappings or deployment detail for classified environments on this website — deliberately. If you operate under VS-NfD or adjacent classification regimes, the relevant material — covering sovereign infrastructure, key custody, trusted execution and attestation in classified contexts — is shared directly, in a closed briefing, with verified counterparts.

Briefing requests are handled by a dedicated team. Expect a verification step before any material is exchanged.
