Mask Personally identifiable information (PII) after PROD to Test refresh

Content

Hi Experts,

We are looking at available options to mask Personally identifiable information (PII) after a refresh from PROD. The test instance is accessed by a fee consultants and we don't want them to access this information.

We are aware that Oracle does provides a paid service where they update the existing PII with junk data during refresh. But apart from that, do we have any options like using a HDL and updating PII fields with Junk data post refresh?

Any insight would be greatly appreciated. If possible, lets share the process being followed by different clients
