Hey, I’m Jacob Hazak also known as kobs0N 👋
🥷 Head of Offensive Security at Zero-Defense Labs, Securing organizations through advanced offensive-security research, penetration testing, and vulnerability discovery.
At Zero-Defense Labs, we serve as an unyielding shield on the digital battlefield.
Attackers only need to succeed once. Defenders cannot afford to rely on second chances.
Our mission is to identify and eliminate vulnerabilities before adversaries can exploit them. Through rigorous security research, advanced offensive testing, and real-world attack simulation, we help organizations strengthen their defenses and confront emerging threats with confidence.
Together, we can build a safer and more resilient digital world.
Let’s strengthen your security posture and turn the internet into a harder target.
Attack. Understand. Defend. Turning adversarial insight into resilient security.
