Founded in 2010 by Stu Sjouwerman, the company was built on the thesis that the human element — employees who click phishing links, reuse passwords, and inadvertently install malware — represents the primary attack vector in the majority of successful breaches, and that continuous, measurable security awareness training combined with simulated phishing exercises is the most effective way to reduce this human risk. KnowBe4 went public in 2021 and was taken private by Vista Equity Partners in 2023 in a transaction valued at approximately $4.6 billion. KnowBe4's platform delivers security awareness training through a library of thousands of content modules — interactive e-learning courses, compliance training videos, security tip newsletters, and gamified assessments — that organizations assign to employees based on role, department, and risk profile. The simulated phishing component sends employees realistic phishing emails drawn from KnowBe4's extensive template library of current threat actor lures and measures click rates, credential entry, and attachment opens, routing employees who fail simulations directly into targeted training interventions rather than waiting for the next scheduled training cycle. The platform's PhishER module provides a security operations capability for managing and triaging actual phishing emails that employees report through the integrated PhishAlarm button, reducing the analyst time required to process real-world phishing reports. KnowBe4's Human Risk Management platform aggregates training completion rates, phishing simulation performance, and risk behavior indicators into a per-user Risk Score that security teams use to identify high-risk individuals and departments requiring targeted intervention. The company's research arm, KnowBe4 Research, publishes quarterly phishing industry benchmarks and top-clicked phishing test reports that have made the company a recognized authority on human-layer threat intelligence. KnowBe4 competes with Proofpoint Security Awareness Training, Mimecast Awareness Training, and Hoxhunt in the security awareness market. ## Frequently Asked Questions ### How does KnowBe4 measure whether security awareness training is actually reducing employee susceptibility to phishing over time? KnowBe4 measures the Phish-prone Percentage — the proportion of employees who click on simulated phishing emails — as a baseline and tracks it over time as employees receive training and participate in ongoing phishing simulations. Organizations typically see baseline Phish-prone Percentages of 30 to 40 percent among untrained employees, which KnowBe4's research shows reduces to below 5 percent after 12 months of continuous training and simulated phishing, providing a quantifiable metric that security leaders can report to executives and boards as evidence of risk reduction from the security awareness program. ### What is KnowBe4 and who founded it? KnowBe4 is the world's largest security awareness training and simulated phishing platform, founded in 2010 by Stu Sjouwerman. The company was co-founded with backing and strategic input from Kevin Mitnick, the legendary ex-hacker and social engineering expert, whose background shaped KnowBe4's focus on human-centered security education. KnowBe4 went public on Nasdaq in 2021 and was taken private by Vista Equity Partners in 2023. ### What products does KnowBe4 offer? KnowBe4's core platform provides phishing simulation (sending fake phishing emails to test employee susceptibility), security awareness training content (video courses, modules, assessments), and analytics. Its AI-powered PhishER product automates triage of reported suspicious emails. SecurityCoach provides real-time security coaching to employees triggered by risky behaviors detected across integrated security tools. ### How does KnowBe4 SecurityCoach work? SecurityCoach integrates with security tools like CrowdStrike, Microsoft Defender, and web proxies to detect risky behaviors — visiting phishing sites, downloading suspicious files, using weak passwords — and automatically delivers targeted in-the-moment security coaching to the employee who triggered the detection. This real-time feedback loop is more effective than periodic training at changing the specific behaviors creating risk. ### What is KnowBe4's PhishER platform? PhishER is an email security orchestration platform that automates the triage, analysis, and remediation of phishing emails reported by employees. When employees report suspicious emails using KnowBe4's Phish Alert Button, PhishER automatically analyzes indicators, categorizes the threat, and can pull malicious emails from all employee inboxes — turning employee reporting into an automated incident response capability. ### How does KnowBe4 compare to Proofpoint and Cofense for phishing defense? KnowBe4 leads on simulation library size (20,000+ phishing templates), training content breadth, and market share for pure security awareness training. Proofpoint includes an email gateway with intelligence on real threats. Cofense leads on incident response automation for reported emails. Many large enterprises use all three: Proofpoint for email filtering, KnowBe4 for simulations and training, and Cofense or PhishER for reported email response. ### What is the KnowBe4 AI Cyber Defense Agent? KnowBe4 launched an AI-powered security awareness agent that automatically creates personalized phishing simulations based on each employee's risk profile, organizational role, and historical susceptibility patterns. This moves beyond manual simulation scheduling to continuous AI-driven employee testing that adapts as the organization's threat landscape and employee skill levels change over time. ### Does KnowBe4 offer compliance-aligned training content? Yes. KnowBe4 offers compliance training modules for PCI DSS, HIPAA, GDPR, SOC 2, and industry-specific requirements. Organizations can assign required compliance training alongside phishing simulations and track completion for audit purposes. KnowBe4's compliance content is regularly updated to reflect regulatory changes and is available in 35+ languages for global deployments. ## Tags saas, b2b, cybersecurity, security, platform, enterprise, smb, north-america, public, global --- *Data from geo.sig.ai Brand Intelligence Database.
