Penetration testing involves simulating real-world cyber attacks to identify vulnerabilities in Andorid/iOS/Web applications before malicious actors can exploit them. As a penetration tester, I utilize a combination of automated tools and manual techniques to comprehensively assess security posture. This includes identifying weak configurations, insecure coding practices, and potential entry points for attackers. I provide detailed reports that not only highlight vulnerabilities but also prioritize them based on their severity and potential impact on the business. My recommendations focus on practical remediation steps, helping clients strengthen their defenses and reduce the risk of data breaches or unauthorized access.
