Overview

Product Information on KnowBe4 Cloud Email Security

Updated 13th October 2025

What is KnowBe4 Cloud Email Security?

KnowBe4 Cloud Email Security is a software designed to help organizations defend against a range of email-based threats, including phishing, malware, and spam. The software leverages machine learning and behavioral analysis to detect suspicious emails and prevent harmful content from reaching user inboxes. It provides centralized management, real-time reporting, and integrates with existing email platforms to enable administrators to monitor and configure security policies effectively. The software addresses the business problem of safeguarding sensitive information and business processes from email-driven cyberattacks by filtering incoming messages and offering automated remediation to reduce risk and enhance email security posture.

KnowBe4 Cloud Email Security Pricing

KnowBe4 Cloud Email Security software uses a subscription-based pricing model, typically structured by the number of users or seats. Pricing includes access to core email security features, and may vary depending on the selected plan or required functionality. Additional features or professional services may be available at extra cost. Annual and multi-year licensing options are generally offered for organizations requiring longer-term usage.

“KnowBe4 Provides an Awesome E-mail Security Platform”

5.0
Mar 2, 2026
The KnowBe4 (formerly Egress) E-mail security products, Defend and Prevent are very effective in preventing and mitigating phishing attacks as well as accidental data loss events. Our users have accepted and embraced these products and that has enhanced their effectiveness. Egress Support has been excellent both in responding to questions and issues and in configuration of the products, but has degraded a bit since KnowBe4 acquired Egress.

“Phishing Simulations Effective But Reporting and Assessment Setup Presents Difficulties”

3.0
Feb 24, 2026
The overall KnowBe4 experience has been good, however we have faced challenges. Limited new training content, Preferred training languages readily available and setting up the SAPA and managing communications through the dashboard was complex and created difficulties. Not using all of the KnowBe4 products also impacts how accurately the VRO score reflects our organization.

KnowBe4 Cloud Email Security Likes & Dislikes

Like

Ability to apply domain/address blocks to incoming email using the Deny List Support Functionality of the Products Interactive prompts Configuration options Training support for end users The products are not obtrusive and do not consume too much bandwidth

Like

1) The platform is easy to use for both administrators and end users 2) Reporting and tracking features provide helpful visibility into user engagement and progress 3) The phishing simulations are highly effective and realistic, helping users build practical awareness and confidence in identifying threats

Like

Proactive user intervention - Context-aware prompts and encryption triggers that help prevent accidental or intentional data exposure in real time, reducing human error. Strong Microsoft 365 integration - The seamless integration with Exchange Online enhances email security and provides a layer of security beyond native capabilities. Visibility and oversight - Policy management and reports give us insight into sensitive email activity so we can provide support to the compliance team.

Dislike

We have experienced some advanced phishing attacks that evade Defend Defend does not alert on plain text e-mail messages Would like to be able to generate and download meaningful reports

Dislike

1) Some functionalities - setting up assessments and sending out communication through the dashboard are complex and not very intuitive 2) While additional training is available on request, the process is tedious and time consuming, which creates challenges for teams and regions that rely on them 3) The VRO score does not accurately reflect the overall risk level when an organization does not utilize the full suite of Knowbe4 products, which can lead to misinterpretation of the overall risk level. Additionally, new users are regularly onboarded and having their risk score remain high for 90 days inaccurately skews the organization's overall risk score, making improvements difficult.

Dislike

User learning curve - End users might find the prompts and notifications confusing, requiring additional support from our end. Reporting depth - While useful, reporting should be more advanced and provide customization and analytics. Administrative complexity - Policy tuning and rule refinement require adjustments occasionally.

    Egress: Advanced Rule Configuration and Data Loss Prevention

    5.0
    Nov 27, 2025
    Egress has detailed and granular rule configuration allowing for very specific coverage to fit out exact needs. The prevent dashboard has a large array of detailed information and allows us to monitor and check for data loss across the company. Defend also works very well, allowing for easy monitoring of incoming dangerous emails. The abuse mailbox is particularly good, reducing the amount of time that we previously had to spend analysing user reported emails.
