From military tiger teams to AI-driven security, discover how penetration testing has evolved—and why it’s more crucial than ever.
The Origins of Ethical Hacking
Penetration testing has been shaping cybersecurity for decades—long before modern enterprises recognized its necessity. What started as a niche practice among military strategists, security researchers, and curious hackers has now become a boardroom imperative.In The History of Pentesting, we explore the evolution of cybersecurity through key moments, from the first “tiger teams” in the 1970s to today’s AI-powered security solutions.
Why This Documentary Matters
Cyber threats have never been more sophisticated, and businesses can’t afford to rely on outdated security strategies. This documentary will take you on a journey through:
- The early pioneers of penetration testing – How military and government initiatives laid the groundwork.
- The rise of ethical hacking – How hacker culture influenced cybersecurity’s development.
- Automation and AI in security – How technology is changing penetration testing today.

“There’s no equivalent of turning the map around in traditional cybersecurity. Military strategists have always red teamed their battle plans to see what an adversary sees, but in cybersecurity, organizations have relied on best practices and assumptions rather than real validation. That’s why penetration testing is essential—it forces you to confront the gaps attackers will inevitably find.”
– Snehal Antani, CEO & Co-Founder, Horizon3.ai
Pentesting in the Modern Era: The NodeZero® Advantage
History has shown us that security isn’t just about defense—it’s about thinking like an attacker. Traditional penetration testing is slow, expensive, and often outdated before the findings can be acted upon.
NodeZero changes that.
Horizon3.ai’s NodeZero enables organizations to:
- Continuously validate their security posture from an attacker’s perspective.
- Identify real, exploitable weaknesses before attackers do.
- Generate actionable, executive-friendly reports in hours—not weeks.
