My name is Taysir Zaituni, also known as TAYSIR SEC. I am a cybersecurity specialist, ethical hacker, and content creator with a strong focus on ethical hacking education and security awareness. My interest in cybersecurity started at a young age and became professional in 2016. Since then, I have focused on understanding systems from the inside-analyzing security mechanisms, identifying weaknesses, and delivering practical security solutions rather than simple vulnerability findings. I specialize in web application and infrastructure penetration testing, with experience in Web Security, Bug Bounty, VPS environments, networking, Linux systems, and penetration testing tools, following industry best practices. In parallel, I create educational content on YouTube and Twitch, helping beginners understand ethical hacking, security fundamentals, and digital privacy. My goal is to build more secure systems and help individuals and organizations protect their applications and infrastructure through ethical research and continuous learning.
