Prevent general settings let you balance your organization's security needs with user productivity. This article walks you through the general settings you can configure for your deployment, including managing the add-in, your internal domains, email visibility in the Prevent console, and managing email nudges for your users.

KnowBe4 Email Security Add-In

The KnowBe4 Email Security Add-In card allows you to download the add-in manifest, ready for deployment to your organization. This card also allows you to manage how the add-in delivers security and configure real-time nudge timeouts to balance email scanning speed with user productivity.

Download Manifest

To download and install the KnowBe4 Email Security Add-In, select the Download Add-In Manifest button and follow the instructions provided in the Web Add-In - Deployment Guide for Prevent article.

Internal Domain Management

Internal domain management helps the Prevent console accurately calculate email risk levels by distinguishing between internal and external recipients. This action is particularly important for detecting anomalies such as misdirected emails. Without a comprehensive list of internal domains, your organization's domains may be incorrectly classified as third parties.

To add internal domains, follow the steps below:

1. Log in to your Prevent dashboard.
2. Navigate to Prevent Settings > General > Internal Domain Management.
3. Select + Add Internal Domains.
4. In the pop-up window, enter the domain to add to your organization's internal domains list.
5. Confirm that the domain belongs to your organization.
6. Select Add Domain.

To remove an internal domain, follow the steps below:

1. Log in to your Prevent dashboard.
2. Navigate to Prevent Settings > General > Internal Domain Management.
3. Locate the domain you wish to remove.
4. Select Delete on the line containing the domain name.
5. Select Confirm in the confirmation pop-up window.

Email Visibility

You can control which email information is displayed in your Prevent console. Before enabling these settings, consider your organization's privacy policies. Enabling these settings may expose sensitive details to admins, so ensure you have the necessary internal sign-off.

The following options are available for you to enable or disable:

• Display Attachment Names
• Display Email Subject Lines

Nudge Experience

Prevent's Nudge Delivery Experience settings control how and when users see Prevent's guidance on outbound emails. Admins can choose between two delivery modes. Real-Time Mode checks a message before it's sent and, if needed, shows the user a nudge in the Microsoft Outlook add-in. Hybrid mode sends the message right away and follows up with an email notification if the Prevent Gateway flags a concern afterward.
