About KnowBe4, Inc.
KnowBe4, Inc. is a U.S.-based cybersecurity company focused on the human-risk layer of enterprise security. The company was founded in 2010 in Clearwater, Florida, and built its franchise around security awareness training, simulated phishing campaigns, and behavior-based coaching designed to reduce the user error that often enables cyberattacks. Its global headquarters remains in Clearwater, and the company says it has expanded into 11 countries, underscoring an international commercial footprint even though its operational roots are firmly in the United States. KnowBe4 is associated with the American market, and its shares were previously listed on a major U.S. exchange before the company was taken private. ([knowbe4.com](https://www.knowbe4.com/careers/locations/usa?utm_source=openai)) From a corporate history perspective, KnowBe4 evolved from a security-awareness specialist into a broader human-risk management platform. It completed an IPO in 2021, was taken private by Vista Equity Partners in 2023, and then continued to broaden its product scope through innovation and acquisitions. A key strategic step came in 2024 with the completion of the Egress acquisition, strengthening KnowBe4’s email-security and remediation capabilities. In 2025, the company appointed Bryan Palma as President and CEO, while founder Stu Sjouwerman moved into the role of Executive Chairman. ([knowbe4.com](https://www.knowbe4.com/about-us/?utm_source=openai)) KnowBe4’s core business lines center on an integrated platform for human risk management: security awareness training, phishing simulations, real-time coaching, reporting and analytics, and automated response tools for suspicious emails. The platform is now marketed as HRM+ and includes the AIDA suite, which uses AI to personalize training, generate phishing templates, and automate selected security workflows. Strategically, that places KnowBe4 in competition with cybersecurity training vendors, email-security specialists, and broader security software providers that are increasingly adding user-risk capabilities. ([knowbe4.com](https://www.knowbe4.com/products/human-risk-management-plus?utm_source=openai)) Commercially, KnowBe4 says it serves more than 70,000 organizations worldwide, giving it a meaningful installed base and recognizable brand in the awareness-training category. For investors in France, Belgium, and Switzerland, the company is best viewed as a niche cybersecurity platform with a recurring-software profile, a strong product-led go-to-market model, and a differentiated position in human-risk reduction. Recent company updates in 2026 included product refreshes and phishing-threat trend reports, which suggest continued investment in platform depth and customer engagement. While the company is no longer publicly listed today, its history on the U.S. market and its former NYSE/NASDAQ profile remain relevant for assessing its financial trajectory and competitive standing.
