Resource web-app security review
Muhammad performed a thorough penetration test and security review of my web app, clearly identified vulnerabilities, and delivered a well-structured report with prioritized, actionable recommendations. His communication was fast, clear, and professional throughout the project, and he always took the time to explain things and answer questions. After I addressed the findings, he promptly performed retesting and verified that the fixes were effective. He is a nice person and a pleasure to work with. I highly recommend Muhammad for any web or API security assessment and would be happy to work with him again.
