# Supplier Onboarding and Review Procedure
## Purpose
This procedure defines how BlackDice should assess, onboard, record, and review suppliers relevant to the ISMS scope.
## Scope
This procedure applies to suppliers providing technology, hosting, support, development, data processing, operational, or other services that may affect security, resilience, or compliance.
## Trigger / When Used
Use this procedure when:
- a new supplier is proposed
- a supplier's role or service scope materially changes
- periodic supplier review is due
- a supplier incident or assurance concern triggers reassessment
## Procedure Steps
1. Record the proposed supplier, service description, owner, and business rationale.
2. Determine the supplier's risk tier based on access, information handled, service criticality, deployment model, and dependency importance.
3. Perform due diligence appropriate to the risk tier, including security, privacy, resilience, contractual, and shared-responsibility considerations.
4. Review the due diligence outcome and identify any required contractual controls, remediation actions, or risk acceptance decisions.
5. Obtain approval to onboard or continue using the supplier where required.
6. Record the supplier in the approved register with ownership, status, review cadence, and assurance references.
7. Perform periodic review and reassessment based on risk, incidents, material changes, or expired assurance evidence.
8. Track remediation actions, exceptions, and reassessment outcomes to closure.
