Note
The Content Inspection with Automated Encryption tab is only available on an account that has the Advanced Managed Email Security license.
In Email Security > Content Inspection with Automated Encryption, you can select predefined policies for content inspection and add a keyword to bypass content inspection. You can also create your own custom content policies.
Custom content policies allow you to create specific rules so that certain emails will be encrypted. They are prioritized over predefined policies when it comes to assessing emails for encryption. This means that when an email is received by EncryptTitan to be assessed for encryption, a check is performed to see if Content Inspection with Automated Encryption is enabled. If it is, then the next check determines if custom content policies have been created and enabled. If so, custom content policies are applied for email encryption.
If there is no policy match, then the following checks are considered to determine if the email should be encrypted:
Is there an Outlook Plug-in or Add-in header?
Is there a keyword in the email subject?
Are there predefined content policies enabled for assessment?
For help creating custom content policies and selecting predefined content policies, go to Create Custom Content Policy and Select Predefined Content Policies respectively.
The custom content policies you create are listed in a table in Configurations > Email security > Content Inspection with Automated Encryption. The order of custom rules is taken top down in the table with the rule at the top being assessed first. If a match is found in an email, the mail will be encrypted based on that rule. If not, the next rule is assessed. You can set the priority order by selecting a rule and pressing the up/down arrow .
In addition to creating custom content policies, you can also:
Search: To search for a policy, enter part or all of the policy name in the search field and press Return. You can select Refresh at any time to update the data on the screen.
Edit: You can edit custom content policies as well as disable/enable them by selecting the checkbox beside the policy and selecting Edit. Follow the instructions below for assistance.
Delete: To delete a custom content policy, select the checkbox beside the policy and select Delete. You'll be prompted to confirm your decision in a pop-up message.
To create a custom content policy, follow these steps:

Select Update.
Note
For Advanced Managed Email Security license, note the following:
If content inspection is enabled and an email has content that matches a policy that is enabled, then the email delivery method will be based on the secure delivery method enabled on the customer account.
If all three delivery methods are enabled [Secure Delivery Method 01: TLS; Secure Delivery Method 02: No Registration Required (NRR); and Secure Delivery Method 03: Registration Required (RR)] then TLS delivery will be attempted first. If TLS fails, then NRR delivery will be used.
If one or more keyword(s) are set up for email encryption and an email has one of the keywords in the subject line, then that email will be delivered using the specified delivery method. It will not be assessed for content inspection.
If there is no encryption keyword in the email subject line and content inspection is enabled, then the email will be assessed for content that matches the enabled policies. If a match is found, the email will be encrypted.
