FOYSAL MAHMUD

Authorized, simulated attacks against your systems — executed exactly like a real adversary would. I probe your infrastructure for the weaknesses an attacker would find first, then hand you a risk-rated report with proof-of-concept evidence and a remediation roadmap — before someone with worse intentions finds the same doors.

Deep-dive security assessments where automation meets craft. Scanners find the obvious; I hunt the logic flaws, chained misconfigurations and business-logic abuses that tools can't reason about. Web apps, APIs, networks and mobile — every finding delivered with PoC evidence and business-impact analysis.

Strategy before tooling. Threat modeling, risk assessment, incident-response planning and security culture — tailored to your risk landscape and budget, not a generic checklist. Whether you're a startup shipping your first product or an organization hardening what already exists, I help build a posture that lasts.

I don't just find vulnerabilities — I know how they get written. Landing pages, platforms and web applications built secure by design: validated inputs, hardened headers, sane auth, clean architecture. The rare developer who has read your codebase from the attacker's side first.

What does the internet already know about you? Open-source intelligence gathering and digital-footprint analysis that shows exactly what an attacker learns before they ever knock on your firewall — exposed records, leaked credentials, metadata trails — and how to shrink that footprint.
