Testing using real data of the customer



  • Is it common to use real data of the customer to perform testing? What policies companies apply regarding using real data of the customer for testing purposes? Is there any legislations regarding such issues?



  • Depends on your definition of testing, anonymized data is widely used by Microsoft and others for monitoring and testing in production, it's the basis for A/B testing or monitoring for example.

    In Europe the GDPR does not allow usage of private data, but the GDPR does not apply to anonymised information and anonymised data can be used without consent. Anonymised data is defined as “data rendered anonymous in such a way that the data subject is not or no longer identifiable.”

    Be careful though, you need to be careful on how data is anonymised and make sure it is really irreversible.
