Create Custom Advanced Patterns

You can define custom advanced patterns to identify your sensitive data. Advanced patterns use regular expressions (regex) that allow pattern matching to identify sensitive data such as social security numbers or credit card numbers. They can also use a validation algorithm to validate the regex. 

Skyhigh Security built-in advanced patterns cannot be edited.
