KnowBe4 Enables Organizations to Have Independent Control Over Outbound Email Security

KnowBe4 Combats Human Mistakes with Simple, Dual-Layer Data Protection for SMBs

TAMPA BAY, Fla.--(BUSINESS WIRE)--KnowBe4, the global leader in digital workforce security, securing both AI agents and humans, today announced the launch of two easy-to-use features, Prevent’s DLP rule builder and misdirected content analysis, offering advanced data protection for all customers. These features are particularly valuable to Small and Mid-Market (SMBs) organizations, delivering enterprise-grade security without the typical premium costs of additional licensing or expensive professional services.

Most sensitive data loss is due to simple human mistakes, not malicious intent, but traditionally, the tools to stop these errors were complex and expensive. With Prevent’s DLP rule builder and misdirected content analysis, organizations can now secure outbound email with ease and without the high price tag.

The new features allow organizations to independently secure outbound sensitive data like Personally Identifiable Information (PII) and financial records.

• Prevent DLP Rule Builder: Admins can easily create and manage their own rules to block unauthorized emails. They can set smart controls, for example, telling a rule to only block an email if it contains multiple pieces of sensitive data. This level of control reduces false alarms and helps organizations meet compliance rules like HIPAA and GDPR on their own.
• Misdirected Content Analysis: The AI-powered feature detects when data is about to be sent to the incorrect person. It provides a context-aware warning to the user before the email is sent, turning a near mistake into a teachable moment.

"For small and mid-market organizations, data protection often feels overwhelming, it's expensive, complex, and requires specialized skills,” said Greg Kras, chief product officer at KnowBe4. “KnowBe4 Prevent changes that. We're delivering enterprise-grade protection that combines high-fidelity DLP with AI-powered misdirected content analysis. This dual-layer defense not only gives organizations the autonomy to secure sensitive data like PII and financial records, but it also turns every near-miss into a teachable moment that proactively corrects human behavior, which is the root cause of most data leaks."

KnowBe4 Prevent is the only standard outbound security offering that combines high-fidelity data protection (what is in the message) with AI-driven checks on the recipient (who is receiving it). The product redefines outbound email security for SMBs by offering the independent control they previously lacked. With the launch of the Prevent DLP rule builder and misdirected content analysis, KnowBe4 provides a defense that is both powerful and simple to implement. It uniquely addresses the security gap for SMBs, ensuring that advanced protection of sensitive data is in place while simultaneously building a more secure and aware workforce.

These features will be available in June 2026. Learn more at www.knowbe4.com.
