What does 'flow-down' mean in vendor subprocessor management?

• A. Onboarding new vendors to increase coverage.
• B. Transferring contract obligations to subprocessors through the primary vendor's contract.
• C. Terminating the primary vendor's contract.
• D. Outsourcing internal IT support.

Answer: (B)

Flow-down means the obligations in a vendor contract are extended to any subprocessors the vendor uses. In practice, the primary contract requires the vendor and any subcontractors to comply with the same security, privacy, breach notification, and audit requirements. This cascading responsibility keeps data handling and controls consistent across the entire chain, so your protections stay in place even when processing is outsourced to a subprocessor. If a subprocessor doesn’t meet obligations, the primary vendor is contractually responsible for remedy, and you often retain rights to approve or challenge subprocessors. This is why transferring contract obligations to subprocessors through the primary vendor’s contract is the correct interpretation. Onboarding more vendors, terminating the primary contract, or outsourcing internal IT support do not describe this cascading transfer of duties to subprocessors.
