The organization must inform the customer in a timely manner of the basis for transfers of personal data between jurisdictions and of any intended changes, so the customer can object or terminate, documenting compliance with the legislation and regulation that applies depending on origin and destination, informing the customer of transfers to suppliers, other parties and other countries or international organizations, giving advance notice of changes within an agreed timeframe, setting the limits of any contractual allowance to make changes without informing the customer, and identifying the instruments relied on for international transfer together with the countries involved and the circumstances in which they apply.
ISO 27701:2019 8.5.1 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.
