Built-in Identifier Reference
Immuta comes with a set of built-in identifiers that look for common data types. These identifiers were written by Immuta's research and development team and cannot be deleted or edited by users. However, users can add these built-in identifiers to their own frameworks and edit the tags applied by them.
Identifiers must match at least 90% of the sampled data to be tagged, with two exceptions noted below. See the How competitive pattern analysis works guide for more information about sampling and thresholds.
Deprecation notice
The following Discovered tags have been deprecated:

New SaaS tenants will not see these tags applied by SDD. Current tenants relying on these tags for policies should contact their Immuta representative for support before these tags are removed from the product in December 2024.
