Customer-service work can involve access to information on behalf of other organisations. An audit can follow the agreed responsibilities and access arrangements without repeating an unverified claim about the size or origin of a breach.
Questions to follow in an audit
- Which information is made available to each supplier?
- How is access approved, limited and reviewed?
- How are suspected incidents notified and investigated?
Connect the records with practice
Trace one supplier service through its agreement, staff access, review records and incident communication arrangements.
These are illustrative audit trails, not findings about a named organisation, technical instructions or a guarantee of a particular result. The appropriate evidence depends on the activities, risks and agreed scope. The organisation remains responsible for its operations and legal obligations.
