DLP Content Filtering

Use the DLP Content Filtering section to define the rules that apply to secure and non-secure messages. Blacklist keywords and algorithms (regular expressions / REGEX) and enforce messages to be sent secure based on keywords and algorithms (regular expressions). This section only defines the DLP rules used with the Outlook Toolbar. Refer to the Secure Messaging Gateway documentation for information on DLP configurations with the Gateway.

Web Admin Console Content Filtering
  1. Blacklisted Keywords / Algorithms Presets: Pre-defined algorithms for SSN numbers and Credit Card numbers can be selected.
  2. Blacklisted Keywords / Algorithms Custom: This option blacklists specified keywords or algorithms, preventing users from including them in outgoing messages. Any word or set of words/characters can be entered into the text area as a regular expression. In its most basic form, you can enter words separated by the ‘|’ character. For example: ‘tax|money’ will blacklist a message that contains either the keyword ‘tax’ or ‘money’. Please note that it is NOT case sensitive and spaces within a string requires a REGEX.
  3. Default Secure Keywords / Algorithms Presets: Pre-defined algorithms for SSN numbers and Credit Card numbers can be selected. Blacklisting takes precedence over these settings.
  4. Default Secure Messages with File Attachments: There is also an option to require any message with file attachments to be sent secure. An exception for embedded images (e.g. email signatures) is also an option.
  5. Default Secure Keywords / Algorithms Custom: This option forces a user to send the message as a secure message if it contains the specified keywords or algorithms. Any word or set of words / characters can be entered into the text area as a Regular Expression. In its most basic form, you can enter words separated by the ‘|’ character. For example: ‘tax|money’ will trigger default secure for a message that contains either the keyword ‘tax’ or ‘money’. Please note that it is NOT case sensitive and spaces within a string requires a REGEX. Blacklisting takes precedence over these settings.
  6. Domain List: use this area to specify specific email domains where all messages sent to those domains require to be sent secure.
