Connects contracts, vendor masters and document stores, then verifies the authenticity, validity and scope of certificates, attestations, SBOMs, pen-test reports and policies.

Auto-classifies vendors into critical, important and baseline tiers by dependency, concentration and evidence quality, re-tiering the moment evidence changes.
Produces cited, exportable evidence trails mapped to all ten NIS2 Article 21(2) measures, plus Article 23 incident-notification drafting with 24-hour early-warning timing.
