DLP Content Scanning


How can you ensure that your users are not accidentally (or intentionally) sending out sensitive or restricted information?

SendGuard can scan email contents (body, subject and attachments) for specific words or data patterns and warn/block users if it finds any potentially sensitive or restricted content.

SG DLP Prompt

IT admins can configure SendGuard DLP to scan emails for Credit Cards, Social Security Number, Profanity Lists. Regular Expressions (Regex) can be used to define any search pattern or word list.

The prompts can also be configured to allow different options based on the severity of the information detected (e.g. block the email or allow with user confirmation).

SendGuard can be configured to keep a log if users choose to send out an email despite the warning.

How to Set Up DLP Content Scanning?

  1. Open Outlook.
  2. Click on the Standss Outlook Addins tab on the ribbon.
  3. Click on SendGuard and then click Settings to open the Settings screen.
  4. Click on the Data Loss Prevention tab.

  10. Type Rule Name to be displayed on prompt.

You can define what you want scanned and the associated actions either in the registry or on the DLP tab of the settings screen.

SG DLP Settings

You can define multiple DLP Rules on this screen. Each new rule must start on a new line and end with a semi-colon (;).


Each DLP content has 3 parts to it, these are:

  • Type: This is a text description of the type of DLP (E.g. Credit Card, SSN)
  • Action: The Actions are the types of actions to take when some content is found. These actions have severity levels:
    • Block: This is the highest severity level where the user is not allowed to send the email
    • TypeSend: This is the medium severity level where the user has to type SEND before clicking Send
    • CheckBox: This is the lowest severity level where the user has to tick a checkbox before sending.
  • Regex: This is the regular expression which is used to search in the email or attachments.
  • Add multiple DLP Rules by separating them using a semicolon (;)
