KnowBe4, a global cybersecurity platform specializing in human risk management, has announced the full market release of KnowBe4 Prevent, an AI-driven email security product designed to manage outbound email risk. Following the initial launch of Prevent Enterprise, this solution is now available for organizations of all sizes, including small to medium-sized businesses.
Outbound email risk remains a persistent challenge for organizations, often leading to significant financial losses and reputational damage. According to Verizon, human error continues to be a primary cause of data breaches, with 60% of incidents in 2025 projected to involve human elements. The increasing volume of digital communications amplifies opportunities for employees to inadvertently expose sensitive information through misdirected emails, incorrect attachments, or accidental inclusion of confidential data.
Traditional Data Loss Prevention (DLP) solutions typically rely on static rules, which often lack the real-time visibility and adaptive intelligence needed to effectively prevent such incidents. KnowBe4 Prevent addresses these limitations by utilizing artificial intelligence to alert employees in real-time before they send emails or attachments to unintended recipients. The platform proactively detects and mitigates a broad spectrum of outbound email security threats, including misdirected emails (even those caused by autocomplete), unauthorized sharing of sensitive information, replies to suspicious emails or newly registered domains, and data exfiltration attempts by malicious insiders or compromised accounts.
For enterprise-level users, Prevent Enterprise offers additional features such as detecting hidden data within attachments and preventing internal unauthorized disclosure or breaches of information barriers. Security teams benefit from detailed reporting and analytics, which provide a comprehensive view of outbound security risks, insights into user interactions with Prevent’s prompts, and quantification of prevented incidents, demonstrating the solution’s efficacy and return on investment.
Greg Kras, chief product officer at KnowBe4, stated, “Outbound email risk continues to be one of the most persistent and costly challenges an organization can face – one that requires smarter, more adaptive approaches to effectively address them. KnowBe4 has a proven track record of effectively addressing Human Risk Management, so we are proud to expand that coverage to include outbound email risk. Prevent is the most intelligent and proactive outbound email security product among today’s email data loss prevention methods. Unlike traditional products, it uses advanced machine learning and contextual understanding of user behavior to identify risky actions in real time and prevent a data breach before it occurs. This allows organizations to stop incidents at the source, empower employees to make safer decisions, and enable security teams to manage and reduce risk at scale.”
KnowBe4, trusted by over 70,000 organizations globally, aims to strengthen security culture and manage human risk through its AI-driven Human Risk Management (HRM+) platform. The platform integrates modules for awareness and compliance training, cloud email security, real-time coaching, crowdsourced anti-phishing, and AI Defense Agents. Publix Employee Federal Credit Union is among the organizations that have utilized KnowBe4’s solutions for outbound data loss mitigation over email.
