Official text

Who it applies to

  • Procurement and third-party risk teams
  • DORA Chapter V compliance owners
  • Industrial operations

Structuring points

  • A critical supplier is not a large supplier: it is one whose absence stops a prioritised activity
  • A contract clause with no audit right and no joint testing proves nothing
  • Tier-2 concentration is the most frequently overlooked exposure

Supplier relationships, outsourcing, critical service providers and concentration.
