While there is a 3rd party solution in the app store (PII Vault), I think Domo should have automated built in PII governance tools integrated into the toolkit. There could be a UI in the governance toolkit where you tick off various standard PII patterns to look for (SSN, Phone, Birthday etc) or even let you define a custom rule. Domo then scans all datasets looking for those patterns and writes out a log of potential datasets/columns that it thinks might sensitive into a table. Admins could then use this data to go review datasets and apply necessary controls around it.
