Sub-processor
A vendor's own vendor that handles your data on its behalf, such as the inference provider behind a SaaS product's AI feature.
Data-protection law requires vendors to list sub-processors and flow contractual obligations down to them. AI features have added a layer most registers miss: the hosted model provider, and sometimes that provider's cloud host. The Fireworks AI breach reached Notion customers through exactly this chain. Ask every vendor with an AI feature which models it runs, where, and under what retention.
