Patterns are deprecated

Patterns are deprecated, embed patterns in Dictionaries instead.


In a future release Discovery patterns will be removed from the left nav, because they are not used frequently. Instead, customers should now embed patterns in dictionaries. If you have any patterns in use, you should move them to dictionaries now.

Patterns are regular expressions (regexes) that match specific data elements in your data resources.

Privacera-supplied regular expressions can match common patterns like email addresses and URLs.

You can also define your own regexes to isolate patterns in your data to augment Privacera's patterns.

  1. From the navigation menu, select Discovery > Patterns.

    • Table/Column Name: Pattern matching is applied based on table or column name.

  5. Using the Regex Status toggle, enable (default) or disable regexes.
