The Product works best on Windows machines as of two years back and since we started using it. After migrating to O365 also MAC OS is supported. But similar products seem to have this issue as well. For the dashboard there is no API available to obtain the data and use in your own dashboard.

KnowBe4 Cloud Email Security Likes & Dislikes

Like

Defend is particularly reliable at stopping phishing campaigns and successfully removing them from the user's inbox. It does an excellent job at preventing threats that other tools may have missed. We also utilise Prevent and Protect - Prevent is excellent at stopping emails going to unintended recipients, flagging for potential DLP violations and providing that quick user training piece around why they may have violated a particular policy. Protect is utilised across the business to send secure messages - it's an excellent service.

Like

It prevents data leakages it works pretty smooth. However to monitor the results we have to use the Egress dashboard. In the beginning it takes some time to learn for our end users, however once that is done it is a walk in the park.

Like

Easy dashboard to navigate Remediation of emails is straightforward Different banners in incoming emails

Dislike

I spend most of my time in the Defend admin portal, so here are a few niggly issues that we have spotted. For example, it isn't possible to bulk select emails to close as either Phish or Not Phish. It would also be beneficial to have another category dedicated to Marketing/Spam. However, we have raised these points with our KnowBe4 team and they are actively looking into solutions to address these. The team has demonstrated a real drive for constructive feedback and they will try and implement all of our suggestions.

Dislike

Provide an API so we can handle the data instead of having to view and login to Egress dashboards.

Dislike

Sometimes emails can be slow to send due to the integration with Microsoft. The KnowBe4 team has brought this to Microsoft, but at this time it still remains an issue. Outlook might have to be restarted as emails wont send out at times due to being signed out from the KnowBe4(Egress) application.

    Color-Coded Email Banners Enhance Phishing Detection in KnowBe4 System

    5.0
    Jan 30, 2026
    The KnowBe4 platform offers a single pane of glass, with some other features we were looking for (encryption and DLP). The ease of use on both an end-user and administration level has been nothing short of exceptional. The email uses a banner system to draw attention to potential phishing emails. This helps break up the standard banners typically configured in a 365 environment such as "This is an external email, do not click links from untrusted sources.... etc". Highlighting the banners with different colors helps draw attention to some things that might not be immediately apparent when viewing a potential phishing email.
