StackHawk vs KnowBe4
Side-by-side comparison of AI visibility scores, market position, and capabilities
StackHawk is a developer-oriented DAST platform that runs dynamic application security tests in CI/CD pipelines to find exploitable vulnerabilities before deployment.
About
StackHawk is a dynamic application security testing platform built specifically for developer teams, designed to run DAST scans automatically within CI/CD pipelines so that exploitable vulnerabilities in running applications are caught before code reaches production rather than discovered later through manual penetration testing or bug bounty reports. Traditional DAST tools were built for security professionals running quarterly manual assessments against production systems — StackHawk repackages DAST as a developer workflow that runs on every build, finding the same class of runtime vulnerabilities that pen testers find but continuously rather than periodically. The platform tests running application instances for SQL injection, cross-site scripting, authentication flaws, API security issues, and other vulnerability classes that can only be detected by actually sending attack payloads to a live application.
KnowBe4 is the world's largest security awareness training platform, delivering simulated phishing, compliance training, and human risk management to 65,000+ organizations.
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.
