I find the vulnerabilities before the bad guys do. Penetration testing, OSINT, web security & consulting — Dhaka, Bangladesh.
Hi, I'm Foysal Mahmud — a professional Cyber Security Specialist and Ethical Hacker with over 3 years of hands-on experience. Currently a student at Notre Dame College, Dhaka, pursuing cybersecurity alongside my studies.
I specialize in identifying vulnerabilities, securing networks, and protecting digital assets from cyber threats. My expertise spans penetration testing, ethical hacking, programming and full-cycle cybersecurity consulting for individuals and organizations.
Every assessment begins with reconnaissance and ends with a detailed remediation plan. Security is not a one-time fix — it's an ongoing commitment. I'm here to be your trusted partner in that journey.
I simulate real-world cyberattacks on your systems — with full authorization — to uncover critical weaknesses before malicious actors can exploit them. Every test ends with a detailed PDF report, risk-rated findings, and a clear remediation roadmap.

End-to-end cybersecurity consulting — from threat modeling and risk assessment to incident response planning. I help businesses build a strong, lasting security posture tailored to their specific risk landscape.

Advanced open-source intelligence gathering and digital footprint analysis. I help organizations understand what data is publicly exposed — and what a sophisticated attacker could learn before launching an attack.

Foysal did an outstanding job on our web application security audit. He found critical vulnerabilities our internal team had completely missed — including an SQL injection that could have exposed our entire user database.
Professional, fast, and extremely knowledgeable. Foysal helped us secure our e-commerce platform before launch, finding 3 critical and 7 medium-risk issues. The penetration test report was detailed, clear, and very actionable.
Working with Foysal was great from start to finish. He explained every finding in plain language, provided PoC screenshots, and gave a clear remediation roadmap. Will definitely work again.
Hired Foysal for OSINT investigation and network security. He delivered a well-organized report within the timeline. Communication was excellent and quality of work exceeded expectations.
