Where it holds a general written authorization, the organization must inform the customer of any intended change involving the addition or replacement of a subcontractor that processes personal data, giving the customer the opportunity to object, and where it changes the subcontractor carrying out some or all of the processing, written authorization from the customer is required before the new subcontractor processes the data, whether through appropriate clauses in the customer contract or a specific one off agreement.
ISO 27701:2019 8.5.8 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.
