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.

Real-Time Nudge Timeout 

The Real-time nudge timeout setting helps you strike the crucial balance between providing real-time security nudges and ensuring email delivery remains fast and smooth.

This setting controls how long email sending pauses while the Email Security Add-In checks if a real-time nudge is needed.

• If the check completes within the set timeout, the user will get a real-time nudge before the email is sent, if necessary.
• If the check takes longer than the set timeout, the email will be held, and the gateway will scan it instead. Users will then receive an email nudge if the gateway detects a policy violation.

We recommend a timeout value of five seconds, which ensures most users receive real-time nudges without noticeably delaying email delivery.

Keep in mind that factors like attachments can impact the time it takes to complete a check. For instance, attachments add about two seconds to the email delivery time.

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

Email Nudges

Manage the email nudges users receive when a real-time nudge is unavailable. This event typically happens when the real-time check takes longer than the set timeout, such as with emails that have large attachments.

Select whether an email should be automatically sent or rejected if a user doesn't action an email nudge. You will also set the timeout window after which this default action happens.
