| Type | What It Does | Use For |
|---|---|---|
| Auto-classification | Detects PII patterns in column names | Compliance, PII tracking |
| Custom tags | Labels you define and apply | Organization, ownership, status |
Common Questions
Does auto-classification read my actual data to detect PII?
No. Auto-classification runs pattern matching against column names, types, and AI-generated profiles - never row values. So a column nameduser_email is classified as PII-email from its name, not from a data scan. See auto-classification for the full detection model.
How do I create a custom tag for something like ‘team ownership’?
Create a tag set in Settings → Tags (e.g.,team:growth, team:platform) then apply it to assets manually, via API, or as a rule (tag any asset in a specific schema with a specific team). See custom tags.
Can I use tags in alert rules to scope notifications?
Yes. Alert rules support tag-based filtering - route allpii:email asset alerts to the security channel, or page only on tier:critical tables. This is typically how teams avoid noisy alerting across heterogeneous data.
Are auto-classification tags guaranteed accurate?
They’re high-precision heuristics, not a substitute for your own review. Cases like columns with ambiguous names (id, value, data) are more likely to be missed or mis-tagged. Treat auto-tags as a starting point for compliance review, not the final word.
