About
KnowBe4 is a cybersecurity company headquartered in Tampa, Florida that operates the world's largest security awareness training and simulated phishing platform, serving over 65,000 organizations across 11 million users. 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.
