Data masking protects sensitive columns by controlling how each one can be viewed, used in audiences, and synced. Hightouch flags likely personally identifiable information (PII) for review, and you assign a privacy level that governs the column everywhere it’s used.
Data masking lets you classify sensitive columns and control how each one can be used across Hightouch. You assign every column a privacy level, and that level applies wherever the column appears: profiles, filter suggestions, analytics, agent responses, and syncs.You manage privacy levels on the Data masking page, under Customer Studio > Governance. You can set the same level per column as you build your schema.Data masking controls columns and values. To restrict which rows a user can access instead, use subsets.
Hightouch automatically flags columns that look like PII and marks them with a warning icon for review. Flagging only applies to unreviewed columns, so it never overrides a level you’ve already set.Filter by PII review for the columns that need review, check each one, and assign the correct privacy level.
Go to Customer Studio > Governance > Data masking. The table lists every column, sorted by most recently updated. Search or filter by model, source, PII category, privacy level, or PII review status to find the columns you want.Find the column you want to classify, then set its level from the Privacy level dropdown on that row. The change takes effect as soon as you select a level, and clears any PII flag on the column.To keep an audit record or review classifications outside Hightouch, select Export CSV. The download lists each column with its model, source, PII category, and privacy level, and respects the filters you’ve applied.
Assign a category to group and filter related columns, such as Email, Name, Birthdate, Address, Phone, or IP address. Categories make it easier to review and manage PII across a large schema.
Data masking is controlled by schema permissions. To edit privacy levels and categories, a user must have Configure schema access on the source.See source-level permissions for details.
