The organization must record transfers of personal data to and from third parties and ensure cooperation with those parties to support future requests arising from its obligations to individuals, which includes transfers from third parties of data modified as a result of controllers managing their obligations and transfers to third parties implementing legitimate individual requests such as erasure after consent withdrawal, holding a policy defining the retention period of these records and applying data minimisation so only the strictly needed information is retained.
ISO 27701:2019 7.5.3 is one control. If you already hold one of the frameworks below, a reviewed crosswalk already says how much of ISO 27701:2019 your existing evidence covers. Hold SOC 2 and 58 of 108 ISO 27701:2019 controls already carry evidence.
Each report names every control your existing framework evidences, every one it does not, the reasoning behind each claim, and the claims that were argued against and rejected. 289 were rejected on the SOC 2 pair alone.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
