I’ve built a custom web application and it’s almost ready for production. Before the public rollout, I want a rigorous penetration test that will expose any weakness and help tighten every layer of security. The assessment must be hands-on and realistic, covering the full stack rather than a purely theoretical review. Scope My priorities are clear: • Code review – comb through the source for injection points, authentication flaws, insecure dependencies, and logic errors. • Network-level probing – map open ports, misconfigured firewalls, and potential lateral-movement paths. • Server configuration – evaluate patch levels, TLS setup, permissions, and hardening of the underlying OS and web server. Primary Goal The sole purpose is to improve the overall security posture of the application; compliance check-boxes are secondary. I expect actionable insights that can be fed straight into our development pipeline. Deliverables 1. Executive summary highlighting critical risks in plain language. 2. Technical report detailing each finding, proof-of-concept exploits, CVSS-based severity, and clear remediation steps. 3. Interactive debrief call or recorded walkthrough so my team can ask clarifying questions. 4. (Optional, if time permits) A follow-up validation test once fixes are applied. Tools & Methodology Feel free to employ industry-standard tooling such as Burp Suite, OWASP ZAP, Nmap, Nikto, or custom scripts; just document the methodology so results are reproducible. All testing must respect the agreed time window and remain within the provided staging environment. If you thrive on uncovering hard-to-find vulnerabilities and can present findings in a way my developers will immediately act upon, let’s lock in a schedule.

Hi, I have around 14 years of experience in QA and Application / Information Security, primarily working on enterprise healthcare and financial systems that handle PHI and sensitive data. Most of my work has been hands-on testing production-bound applications, identifying real security gaps, and helping engineering teams close them before go-live. I currently lead security testing across multiple web applications and APIs. My day-to-day work involves attacking authentication flows, APIs, session handling, token usage, and overall application behavior from a misuse perspective. I also work closely with platform and infrastructure teams to review gateway controls, WAF rules, logging, and deployment-level security gaps that typically surface late in the release cycle. The way you’ve described this engagement aligns closely with how I normally work. I don’t treat security testing as a checklist exercise. I take time to understand how the system actually works and remember how users and integrations interact with it, then challenge assumptions to find issues that are practical and exploitable, not just theoretical. I’m used to presenting findings in a way developers can act on immediately clear prioritization, evidence-backed issues, and practical remediation guidance. I also walk teams through the findings to avoid any confusion during fixes. Let me know if you’d like to discuss timelines and access. Regards, Himanshu

Hi! I can help you ship this safely before launch. I’m a hands-on penetration tester (web + infrastructure) and I focus on finding the real issues attackers actually use not just running scanners and sending a generic report. For your staging environment I will: Review your code to spot injection risks, auth/session mistakes, insecure dependencies, and logic flaws. Test the web app manually with Burp Suite (plus targeted automation) to find things like IDOR, token/session issues, privilege escalation, rate-limit bypass, and misconfigurations. Probe the network side (open ports/services, firewall mistakes, exposed admin panels, lateral movement paths within scope). Check server/security hardening (patch level, TLS setup, permissions, web server settings, headers, logging). What you’ll get: A clear executive summary (what matters, why it matters). A detailed technical report with PoCs, CVSS severity, step-by-step reproduction, and practical fixes your devs can apply quickly. A debrief call or a recorded walkthrough for your team. Optional re-test after fixes if time allows. If you share the tech stack + how users authenticate, I can start immediately and work within your agreed testing window.
