I need a seasoned penetration tester to examine a single production-level URL/Web App using a mix of black-box and gray-box techniques. The focus is on three critical layers of the application—authentication flows, data handling/storage processes, and all input-validation points, etc plus a newer AI integration that powers part of the user journey. What I expect from you: • Comprehensive findings with clear, reproducible evidence: risk rating, root cause, and a practical fix for every issue. • A follow-up consultation that walks me through hardening steps so the platform is ready for our forthcoming Cyber Essentials Plus audit. This includes advice on any policy, logging, or configuration gaps you spot during testing. • For compliance reasons we require interested candidates to be based on UK. If you are comfortable delivering both the hands-on testing and the strategic guidance to close gaps quickly, I would like to hear how soon you can start and how long you will need for each phase.

I'm Iosif Peterfi, 15+ years helping teams turn complex web ideas into reliable platforms. This is my speciality: turning ambitious ideas for AI-assisted clipping editors into reliable, scalable platforms with clear admin controls, configurable pricing, and smooth user journeys. You're building a Twitch VOD clipping editor with AI-powered clipping, imports from local files or URLs, an interactive timeline with drag points and waveform thumbnails, clip management with editable titles and durations, per-clip previews and exports, AI-driven clip suggestions, and a credits-based usage model. The system includes authentication (email, Google, Twitch), an admin dashboard to monitor users, transactions, and AI jobs, a payments flow via PayPal, pricing tiers, a referral program with VIP roles, a chat bot for help, and a configurable subscription price controlled from the admin panel. You also want a public landing with a dark, trust-worthy design, testimonial management, and a referral link system with admin-defined percentage discounts and referrer commissions, plus a dashboard for referrers to track referrals and withdraw funds. My approach focuses on outcomes: a polished landing page, a user-friendly editor, and a robust admin suite. Deliverables include landing + login flows; VOD import and timeline; AI-clip detection; clip preview/export; credits and payments; pricing management; referral and VIP roles; chat bot; admin dashboards for users, transactions, AI jobs,...

Hello there, I will provide a comprehensive penetration testing assessment of your production web application using a combination of black box and gray box techniques, covering all critical attack surfaces with both automated scanning and manual verification. For the network and application layer, I will evaluate authentication workflows, session management, access controls, and privilege escalation paths. I will also assess data handling and storage mechanisms to identify insecure configurations, sensitive data exposure, and improper encryption practices. Input validation points will be rigorously tested for vulnerabilities such as SQL Injection, Cross Site Scripting, CSRF, and API level flaws, along with a focused review of your AI integration to uncover any logic abuse, prompt injection risks, or insecure data flows. I use industry standard tools like Burp Suite, OWASP ZAP, Nessus, and Nmap, combined with deep manual testing to ensure no critical vulnerability is missed. You will receive a detailed report with reproducible evidence, risk prioritization, CVSS scoring, root cause analysis, and clear remediation steps aligned with OWASP Top 10, NIST, and ISO 27001 best practices. I will start right away and deliver within 3 to 4 days, followed by a consultation session to guide you through hardening steps and ensure readiness for Cyber Essentials Plus audit.

I have successfully secured several production-grade SaaS platforms for SOC2 and ISO 27001 compliance readiness, identifying critical vulnerabilities that often evade standard scanning tools. Given that your application is in production, my methodology prioritizes non-disruptive, high-precision testing that mimics real-world threat actors without impacting system uptime or the end-user experience. I specialize in bridging the gap between technical exploit discovery and the evidence-based documentation required to clear rigorous compliance audits on the first attempt. My technical approach begins with a manual reconnaissance phase, focusing on authentication flows and API endpoints to uncover deep business logic flaws that automated tools typically overlook. This is integrated with a rigorous OWASP Top 10 assessment using Burp Suite Professional and custom scripts to detect injection vulnerabilities, broken access controls, and insecure object references. I will provide a prioritized remediation roadmap and a formal report structured specifically to satisfy external auditors, ensuring your team can implement validated patches rapidly. Does your application utilize any specific third-party integrations or OAuth providers that should be prioritized during the initial scoping phase? I would also like to clarify if you have a target deadline for the audit submission so we can schedule the remediation re-test to ensure all findings are closed in time. I am available to jump on a call or exchange messages to align on the rules of engagement and finalize the timeline today; let’s discuss how we can secure your environment and streamline your compliance journey.

Hi there, I will conduct a full penetration test of your web application using black-box and gray-box techniques covering authentication flows, data handling and storage, input validation, and your AI integration layer. Every finding will include risk rating, root cause, reproducible evidence, and a practical fix. For the AI integration specifically, I will test for prompt injection, data leakage through model responses, and any paths where user input reaches the AI without proper sanitization — these are attack vectors that standard pen test checklists often miss. After testing, I will walk you through the findings and provide strategic guidance on hardening steps, policy gaps, logging requirements, and configuration changes needed to pass your Cyber Essentials Plus audit. Timeline: 1 week for testing, followed by the consultation and final report. Questions: 1) Can you provide gray-box access (test credentials, API documentation) from day one, or do you want black-box first? 2) Is the AI integration using a third-party API (OpenAI, Claude) or a self-hosted model? 3) When is your Cyber Essentials Plus audit scheduled? Looking forward to discussing further. Best regards, Faizan
