Tenzai
Autonomous AI agentic penetration testing platform
About Tenzai
Tenzai is a Tel Aviv AI-native cybersecurity company founded in May 2025 that builds an agentic platform for continuous autonomous penetration testing—finding, exploiting and remediating vulnerabilities in enterprise software as an always-on alternative to episodic manual pentests, including code heavily written by AI. Founders Pavel Gurvich (CEO), Ariel Zeitlin (CTO), Ofri Ziv (VP Research), Itamar Tal (VP Engineering) and Aner Mazur (CPO) bring Guardicore (acquired by Akamai) and Snyk experience plus elite Israeli offensive-security backgrounds. In November 2025 Tenzai emerged from stealth with a $75 million seed led by Greylock Partners, Lux Capital and Battery Ventures to scale the platform for large enterprises in financial services, healthcare and technology, with explainability and human approval for suggested fixes.
