Tenzai

Tenzai is an AI-powered cybersecurity company focused on enterprise penetration testing. Founded in 2025 by cybersecurity veterans Pavel Gurvich, Ariel Zeitlin, Ofri Ziv, Itamar Tal, and Aner Mazur, the company develops AI agents that test applications using techniques associated with expert human hackers. Its platform examines attack surfaces, identifies weaknesses that automated scanners may miss, and can connect multiple vulnerabilities into reproducible exploit paths, providing evidence to help security teams investigate and fix issues.

Tenzai offers continuous, scalable testing across applications, alongside guided pentests that customers can scope, direct, and review throughout the process. The company highlights deep testing of complex enterprise environments, business-logic vulnerabilities, and efforts to reduce false positives. It also provides demonstrations and pentest requests for organizations interested in the platform. Tenzai reports that its agents ranked in the top one percent across six capture-the-flag platforms, measured against more than 125,000 human hackers. The company publishes research and security guidance through its blog, covering topics such as offensive AI, vulnerability chaining, and implications for security leaders.
