I’m Z3tharsis, a cybersecurity practitioner and instructor passionate about making complex security concepts simple and actionable. I create courses that blend ethical hacking, open-source intelligence (OSINT), penetration testing, and digital investigations, always with a focus on legality and practical skills.

My teaching style is fast, clear, and hands-on — designed for beginners who want to level up quickly, as well as professionals who want efficient refreshers. Whether it’s OSINT recon, web exploitation, or broader cybersecurity foundations, I focus on showing tools and techniques you can immediately apply in real scenarios.

My goal is to help more people enter and thrive in the cybersecurity field, with a balance of technical know-how, ethical awareness, and real-world applications.
