Mohamed Mostafa

I'm a penetration tester specializing in offensive security. I help companies and website owners uncover exploitable vulnerabilities before real attackers do, and I turn the findings into clear, actionable fixes.
My background combines a networking foundation (CCNA), hands-on bug bounty hunting on international platforms, and cybersecurity training at ITI. I also train aspiring pentesters with DEPI, which means I can explain complex technical risks in plain language to developers and decision-makers alike.
