Preserve the notice and baseline
A subprocessor notification can arrive in a shared procurement inbox while the legal team continues using the service. Save the notice, receipt date, proposed effective date, and the list previously reviewed. Identify the contract and service to which the notice relates.
Route the notice to the privacy and procurement owners promptly. Any objection process or response period needs to be checked against the agreement; do not assume that a generic internal review timetable overrides the contractual mechanism.
Ask about the function performed
A provider may support hosting, model inference, monitoring, customer support, or another function. Those functions can involve different data and access. Request a description specific enough to connect the change to the organisation's workflow.
Record the data categories available to the provider, whether content is accessible, and whether the service is optional. An unfamiliar company name alone does not establish increased risk. Conversely, a familiar brand does not remove the need to understand its role.
Compare the changed data flow
Draw the before-and-after processing path using the vendor's supplied information. For example, a new monitoring provider might receive operational metadata while a new inference provider processes document content. These should not be collapsed into the same matrix answer.
Identify storage and access locations, onward arrangements, and the evidence supporting any transfer-related assessment. Have the privacy team decide the legal implications. Keep the product team's technical explanation alongside, but separate from, that legal conclusion.
Test the impact on approved matters
Check whether the existing approval excluded particular clients, data classes, or locations. A change may be acceptable for public research documents while requiring further review for confidential investigations. Record the affected uses with their owners.
If the vendor offers an alternative configuration, verify what it changes and whether it is available under the purchased plan. Do not approve a hypothetical setting that has not been agreed or enabled. Preserve any temporary use restriction until the evidence gap is resolved.
Close the review with a traceable decision
Record acceptance, an evidence request, a contractual objection, or a decision to stop a particular use. Include the decision-maker and reasoning. Update the approved inventory only when the decision is complete.
A reusable matrix helps compare future notices, but each change needs its own evidence. Keep an accessible record for the matter teams so they can tell whether their current document workflow remains approved after the service change.
