Lexical Expressions

You can configure a content rule to look for particular words, phrases or character patterns sent to or from your organization. These phrases or Lexical Expressions, could include confidential information, sensitive terminology, profanities or user-defined expressions.

Lexical expressions provide a powerful way of preventing specific content leaving or arriving at your Gateway. They are grouped and managed in Lexical Expression Lists which are then used by content rules.

You can also configure specific lexical expressions called Text Entities. Text entities are lexical expressions which detect character patterns such as credit card numbers, identity numbers, or user-defined regular expressions.
