Having recently secured a high-traffic SaaS ecosystem on AWS, I recognize the unique vulnerabilities inherent in cloud-native architectures that exceed standard web flaws. My methodology focuses on uncovering deep logic vulnerabilities and cloud-specific misconfigurations that automated scanners often overlook, ensuring your entire stack is resilient against sophisticated threats. I am ready to apply this rigorous, manual-first testing approach to your application to guarantee the highest level of data integrity and protection for your users. My approach begins with a targeted assessment of the OWASP Top 10, emphasizing broken access control and SSRF within your cloud environment. I will execute an exhaustive audit of your API endpoints and cloud configurations—including IAM policies and container security—to eliminate any potential for lateral movement. Using Burp Suite Professional alongside manual exploitation, I will deliver a comprehensive remediation report featuring validated proof-of-concepts and prioritized fixes. This ensures your team can implement critical patches efficiently, minimizing downtime while significantly hardening your overall security posture. To refine my strategy, could you specify if this covers a public-facing API or a multi-tenant app, and if there are compliance frameworks like SOC2 to address? I’m also curious if you prefer a black-box approach or if documentation is available to accelerate discovery. I’m available for a quick chat to align on the scope; I can also provide a redacted sample report to demonstrate the technical depth you can expect.

Hey — saw your post about needing a cloud app pen test. Most teams underestimate how much business logic and auth flaws slip past basic scans, especially in cloud environments. Quick question before I suggest an approach: Is this app already in production with real users, or are we testing a staging/pre-release environment? I’ve led multiple web and cloud app penetration tests (OWASP, API, auth, misconfig, and privilege escalation), and I’m comfortable delivering clear, actionable findings rather than just a noisy report. If you share the app details, architecture summary, and current cloud provider, I can review and tell you what scope and timeline make the most sense.

Hi there End-to-end application security assessment with clear, actionable findings that’s where a proper penetration test delivers real value. A cloud-based setup with .NET, React, and Azure needs careful validation across application logic, API layers, and infrastructure to uncover both common and deeper vulnerabilities. The assessment will cover: • Full penetration testing across frontend, backend, and APIs • Authentication, authorization, and session handling review • OWASP Top 10 vulnerabilities including SQLi, XSS, CSRF, IDOR • Azure configuration and cloud security checks • Input validation, file handling, and role-based access testing The report will include clear reproduction steps, severity levels, and practical remediation guidance so fixes can be applied confidently. The focus stays on identifying real risks and providing solutions that strengthen the system without disrupting functionality. Quick question Will testing be performed on a staging environment or production with restricted scope? Best regards, Nikunj
