Hi Prasant, I have 6+ years of experience in penetration testing across web and mobile applications. I conduct comprehensive security assessments to identify real world vulnerabilities, validate existing security controls, and measure risk exposure. I follow industry standards such as OWASP Testing Guide v4, NIST SP 800 115, SANS Top 25, and PCI DSS aligned practices to ensure consistent and reliable results. Mobile and Web application testing includes both manual and automated assessments. I perform network penetration testing to identify exposed services, weak configurations, insecure protocols, and access control gaps. I also test web and system components for issues such as SQL injection, XSS, CSRF, authentication bypass, authorization flaws, access violations, RFI, LFI, and insecure configurations. Testing focuses on what an actual attacker can exploit. I work closely with development and IT teams to explain findings clearly and provide actionable remediation steps. You receive a clear report with severity ratings, proof of impact, and practical recommendations. I am confident I can support your security goals and would be glad to discuss scope and timelines. Thank you Venkatesan

Security failures don’t happen in isolation. They happen between layers. That’s exactly where I focus. I bring over 8 years of hands-on penetration testing experience, approaching assessments as adversary simulations across the full stack: Android, web, and backend, validating how flaws chain together rather than treating each layer as a checklist. Scope approach : - 1. Android application Client-side logic, local storage, IPC, API usage, certificate handling, and abuse paths that bypass intended flows. 2. Web application Authentication, authorization, input handling, session management, and business logic weaknesses. 3. Java backend services API authorization, deserialization risks, input validation, access control gaps, and trust boundary failures. Deliverables : - 1. Executive summary written for non-technical stakeholders 2. Detailed technical report with PoCs, affected endpoints, and severity ratings 3. Clear, actionable remediation guidance per finding No noise. No inflated findings. Just real risk, validated end to end. If this aligns, I’m ready to start immediately. — RedPointer
