Sensitive Content FilterSensitive Content Filter can be used as one of the conditions in Codetwo Exchange Rules PRO. It is designed to search the sensitive information in the messages. This type of condition may be very useful in companies that want to avoid situations when the users will send out confidential data e.g. private details, credit card numbers etc. If such information are sent in the messages they may be stolen or abused by unauthorized people. If you apply this condition, CodeTwo Exchange Rules PRO will search and detect such information in the body of the message.
In order to activate this option on the Conditions tab, in the List of Conditions click Add, and then select Sensitive content filter (Fig.1.).
If you do not add Sensitive content filter to the list of Conditions, the rule will not check the content of messages for confidential/sensitive data.

Predefined dictionaries will be displayed in the properties of the Sensitive content filter. You need to choose the proper dictionary by checking the box next to its name, for example Credit Cards. You need to set up minimal score for each dictionary. When the number of defined phrases will reach the score number CodeTwo Exchange Rules PRO will perform defined actions. If you want to check the score number for the group of phrases you need to click the Open dictionary button. You will see a new window with the predefined dictionaries on the left. If you select a dictionary, you can view, edit or add new phrases on the right pane. You may also change the weight number for each individual phrase (Fig. 3). You can read more about the specific options of the dictionary in the Dictionaries chapter.
