How we evaluate sub-processors
- Security posture — SOC 2, ISO 27001, or equivalent evidence of independent audit.
- Privacy posture — ability to sign a DPA with SCCs where relevant.
- Business resilience — availability, redundancy, and incident track record.
- Data minimisation — only the data strictly needed to perform the service.
Right to object
Under our DPA, customers may object to a new sub-processor on reasonable grounds. If we cannot accommodate an objection, the customer may terminate the affected service with a pro rata refund of unused fees.
