How Are Suppliers Classified?

Supplier classification is the systematic categorisation of suppliers by criticality and risk profile — the foundation for risk-based TPRM.

Not all suppliers are equally critical. Supplier classification categorises all third parties by their importance to critical business processes and their risk potential — enabling risk-based prioritisation of monitoring resources.

Classification criteria in TPRM

Typical classification criteria include: (1) criticality — how dependent are critical processes on this supplier? (2) data access — does the supplier have access to sensitive or personal data? (3) system access — does the supplier have access to internal IT systems? (4) substitutability — how easily can the supplier be replaced? (5) regulatory relevance — is the supplier to be classified as critical under DORA or NIS2?

Automatic classification

360TPRM classifies suppliers automatically according to configurable criteria — with direct impact on monitoring intensity and reporting.

Critical vs. non-critical suppliers

DORA distinguishes between critical and important ICT third-party providers — with different requirements for contract design, monitoring and exit strategies. NIS2 requires classification as part of supply chain security. ISO 27001 recommends risk-based classification with at least three tiers (critical, important, standard).

DORA: Critical providers under EU oversight

The EU can place critical ICT third-party providers directly under EU oversight (Art. 31 DORA). Financial entities must report their critical providers to the supervisory authority.

FAQ

How many classification tiers are recommended?+

Three tiers have proven effective: Critical (continuous monitoring, annual audits), Important (quarterly monitoring), Standard (annual review).

Must classification be documented?+

Yes — both DORA and NIS2 and ISO 27001 require documented, traceable classification logic.
