Tenzai Launches With $75 Million to Revolutionize Penetration Testing Through AI
Tel Aviv–based cybersecurity startup Tenzai has officially emerged from stealth mode with $75 million in seed funding, one of the largest early-stage investments in the cybersecurity industry. The company’s mission is to transform penetration testing — a critical yet historically manual aspect of security operations — by using artificial intelligence to continuously identify and mitigate vulnerabilities across enterprise applications.
Addressing a Critical Gap in Modern Software Security
Traditional penetration testing has long been a time-consuming and episodic process, often performed only a few times per year. This model is increasingly inadequate in today’s environment, where software updates and AI-assisted code generation accelerate development cycles and introduce new risks daily.
Tenzai’s platform aims to bridge this gap through automation and continuous assessment. By leveraging AI, the system can mimic the behavior of advanced human testers — sometimes referred to as “red teamers” — to detect exploitable weaknesses in real time. This continuous pentesting capability is designed to help organizations maintain a higher level of resilience without the bottlenecks of traditional security audits.
“Pentesting hasn’t changed much since I was a pentester in high school some 25 years ago,” said Pavel Gurvich, Tenzai’s co-founder and CEO. “Today, AI allows us to bring elite, nation-grade offensive capabilities at a scale and speed that were previously impossible.”
Founders With Deep Cybersecurity Roots
Tenzai was founded by a team of industry veterans with proven success in the cybersecurity and software sectors:
Pavel Gurvich and Ariel Zeitlin, co-founders of Guardicore (acquired by Akamai Technologies for $600 million in 2021)
Ofri Ziv, Itamar Tal, and Aner Mazur, the latter previously serving as Chief Product Officer at developer security firm Snyk
Together, the founders bring decades of expertise in enterprise defense, threat analysis, and security product design — giving Tenzai a solid foundation to scale rapidly in a crowded but high-demand market.
Backed by Leading Venture Capital Firms
The $75 million seed round was co-led by Greylock Partners, Battery Ventures, and Lux Capital, with additional participation from Swish Ventures and other private investors. The funding will support the expansion of Tenzai’s research and development teams, the growth of its AI security engine, and the company’s international rollout across North America and Europe.
Currently, Tenzai is piloting its platform with major organizations in the financial services, healthcare, and technology industries — sectors where real-time vulnerability detection can significantly reduce operational and reputational risk.
The Future of AI-Powered Pentesting
Tenzai’s emergence signals a broader shift toward autonomous cybersecurity systems capable of scaling offensive and defensive operations simultaneously. As enterprises manage hundreds of rapidly evolving applications, continuous AI-driven pentesting may soon become a cornerstone of proactive cybersecurity strategy — redefining how organizations measure and maintain their security posture in the age of AI-driven development.
