Supervision of Grant Thornton as data processor
In Grant Thornton’s standard Data Processing Agreement (DPA), which is made available when we enter into an agreement for services where we act as data processor, it is stated that:
“The data controller may supervise Grant Thornton based on a risk-based approach in accordance with the Danish Data Protection Agency’s supervisory concepts. The supervisory concepts recommended by the Danish Data Protection Agency include:
- Observation of the data processor with internal logging
- Written confirmation from the sub-processor that all requirements in the sub-processing agreement continue to be complied with
- Obtaining the data processor’s certification
- Obtaining the data processor’s ISAE 3000 and/or ISAE 3402 assurance report
- Distribution of a questionnaire to the sub-processor for subsequent evaluation”
When Grant Thornton acts as a data processor, this will typically be in situations where we provide payroll or bookkeeping assistance.
From a risk perspective on behalf of the data controller, we assess that our data processing does not present a high risk to the individual data subject, nor within the data controller’s overall risk assessment.
We take our responsibility to assist the data controller in supervisory activities very seriously. Based on a risk-based approach on behalf of the data controller, we accommodate supervision concept 1 and 2. If, in the data controller’s risk assessment, additional supervision is considered necessary, we accommodate and propose supervision concept 5.
