Production data so often forms the basis of a Test Data Environment and this means real data. Best practice and an ever-increasing set of regulations (HIPAA, GDPR, etc.) tell us we should not or cannot use data that can identify an individual. Simple, but effective, data masking or obfuscation can be employed to remove the ability to identify an individual from the data held in your Test Data Environments, from Name and Address, to SSNs and credit card numbers.
