SULAIMAN ID://i39F

I'm a cybersecurity graduate from Buraydah Colleges' Cybersecurity Department, specialized in IoT security and offensive techniques. My focus is on understanding how everyday smart devices — cameras, routers, locks — can be compromised, and building systematic tools to audit and harden them.

My graduation project, SmartGuard, took 1st place in the department — a full IoT penetration testing framework that automates a 15-step attack and hardening workflow: from WPA2 cracking and RTSP stream hijacking to Defense-in-Depth controls that reduce attack surface by up to 80%.

Beyond the lab, I build security automation tools in Python and TypeScript, and I'm actively expanding into broader penetration testing domains.
