PreventTM - Intelligent Data Loss Prevention for Email
Prevent misdirected emails and stop data breaches before they happen. Machine learning and behavioral AI monitors outbound and internal email traffic—preventing accidental and malicious data loss at the source.
Stop Misdirected Emails and Outbound Data Loss Incidents
Human error remains one of the leading causes of data breaches—especially via email. KnowBe4 Prevent™ reduces that risk by analyzing each user’s communication patterns and applying intelligent DLP to intercept threats like:
- Misdirected emails (wrong recipients or attachments)
- Accidental exposure of sensitive data
- Unauthorized data sharing or exfiltration
It works quietly in the background, providing real-time alerts and contextual guidance directly within Microsoft Outlook and Microsoft 365—before the email is ever sent.
Intelligent technology that doesn’t just look for data, but evaluates context, intent, and relationships to appropriately determine risk.
Warn your users of a potential breach at the point of send, rather than relying on the server to determine what is or isn’t safe.
Maintain regulatory compliance by enforcing information barriers and stopping data from ending up in places it shouldn’t be, like home devices.

“What I like most about Prevent is the platform. It gives me that one pane of glass where I can see what data is being sent to where and if prompts are being ignored.”- Ricky Robertson, Director of Information Security

Misdirected content analysis uses contextual machine learning, your custom policies and integration with Microsoft Azure Information Protection to stop users from accidentally sending sensitive information to the wrong recipient
Since deploying Prevent, I cannot think of a single instance where a colleague has asked about recalling an email they’ve sent accidentally. In fact, the opposite is true: we’ve had direct feedback from colleagues that Prevent actually stopped them from making a mistake.

Prevent’s prompts get employees to stop and think critically in the moment, empowering them to fix errors before an email is sent and becomes a line item to review on an audit log.

The analytic dashboards give us actionable intelligence on…how many Prevent prompts have been accepted and incidents avoided. We can use this intelligence to drive user training and ensure employees receive a more tailored experience.
