Penetration Testing for Web Application

@geologistt

Hello, I'd approach this in three phases: automated scanning across OWASP Top 10 categories using Burp Suite, OWASP ZAP, and Nmap; manual testing of authentication, session management, and access control (specifically checking for IDOR and broken authorization between user accounts); and a server/infrastructure review covering SSL/TLS config, open ports, and outdated services. All testing would be non-destructive, with anything higher-risk flagged and pre-approved by you first. Deliverables: a severity-ranked report (Critical/High/Medium/Low) with reproduction steps and remediation guidance for each finding, plus a plain-language summary for non-technical stakeholders. Happy to sign an NDA and share certifications/sample reports on request. Once you confirm scope (user roles, API count, staging vs. production), I can provide a firm timeline and quote.

Hi there, Saw your project for a full web app pentest covering OWASP Top 10 plus business logic, and the controlled / non-destructive testing requirement - I'll operate strictly within that. Your scope matches my daily work; I can test login flows, API endpoints and the IDOR concerns in the admin panels. What I'll do: ✅ Full black-box and grey-box test: Burp Suite + manual checks on auth, session cookies and access control. ✅ Vuln scan with OWASP ZAP / Nessus, STL review, port/service audit, then reference and rank findings. ✅ Solid remediation report with exact reproduction steps and CVE / effort-based priorities. Staged rollout so nothing slips - I test in dev/staging first, you'll okay everything before production. ✅ Burp Suite, OWASP ZAP, Nmap/Nessus ✅ OWASP Top 10 testing (SQLi, XSS, CSRF, broken auth) ✅ Risk-based manual testing for business logic access ✅ Clear deliverable: full report for devs + summary for your team ✅ Microsoft® Certified: MCSA | MCSE | MCT ✅ 300+ projects delivered, 280+ five-star reviews Why me: I'm available around the clock and I'll keep responses snappy - revises report till it's spot on. One question: do you have two separate environments (prod + staging), and would an NDA be a deal-breaker before access? Confident I'll have your app tested and report in 7 days for $900, and I can start right now. Khalil

Hi, I can help you run a controlled web application penetration test that covers login areas, forms, APIs, user roles, admin panels, and the infrastructure around them. I’ve worked on assessments that combine automated scanning with manual testing, so I know where tools stop and real exploitation begins. My focus would be OWASP Top 10 issues, broken access control, session handling, SSL/TLS review, and any exposed services or outdated components. I’d start with a clear test plan and NDA, then move through black-box and grey-box testing using Burp Suite, OWASP ZAP, Nmap, and Nessus as needed. Every finding would include severity, reproduction steps, and practical remediation guidance, plus a concise summary for non-technical stakeholders. If you’d like, I can outline the timeline and testing approach next. Best regards, Gabriel

@Olywebart

Penetration testing will cover full black-box and grey-box methods focusing on authentication, access control, and APIs using industry-standard tools. Automated scans will target OWASP Top 10 vulnerabilities alongside manual checks of business logic, session management, and SSL/TLS configurations. Reports will be structured by severity with clear reproduction steps and remediation plans. Testing will follow strict non-destructive protocols with pre-approval for risky actions. What are the primary security concerns you aim to address with this penetration test?

Hi, You're seeking a controlled web app security test with clear, actionable findings and remediation steps. I’ve done practical web app pentests against login flows, APIs, and admin surfaces, delivering concise reports that map risks to fixes. Execution: I’d start by validating the current risk surface in a safe scope, run targeted manual testing backed by standard scanners, and reproduce findings with clear steps. I’d emphasize non-destructive testing and align on test windows and rollback procedures before any activity. One technical risk / key challenge: Isolating business-logic flaws while avoiding impact on live data can be tricky. Two clarification questions: 1) What environment is in scope (staging or production), and what are the allowed test windows? 2) Should we prioritize certain business flows (data access between roles) and are there data/privacy constraints we must honor? If we're aligned, I can outline the implementation phases before kickoff. Best regards, Brandon

The hardest part of this job is the black-box approach to user roles and admin panels, so I will simulate different user accounts to access those areas. I will use Burp Suite Professional for proxying traffic and scanning, then manual testing with tools like SQLMap for SQL injection and browser developer tools for XSS and CSRF. For the automated scan, I will configure OWASP ZAP to cover the OWASP Top 10, focusing on injection flaws and broken authentication. I would not use purely automated scanning for the entire test. Automated scans miss context and many logic flaws, so they only scratch the surface. I am a Preferred Freelancer on Freelancer with a 5.0 rating, 100% on time and 100% on budget. What specific user roles and their associated permissions should I prioritize testing access to if multiple exist beyond a standard user and admin? A short call on Freelancer to settle the scope would cover the exact endpoints for the black-box testing and the list of user roles to be simulated.

@mayr81

You’re commissioning a web application penetration test and security vulnerability assessment focused on exploitable risk, not just scanning. I will perform a controlled black-box/grey-box test covering login flows, forms, APIs, user roles, and any admin surfaces, paired with OWASP Top 10-aligned automated checks (e.g., SQL injection, XSS, CSRF, broken authentication, IDOR, and security misconfigurations). Findings will be delivered as a detailed, stakeholder-ready report with severity (Critical/High/Medium/Low), precise reproduction steps, and concrete remediation guidance per issue. I will also validate business logic and access control boundaries (including cross-account data exposure attempts), review SSL/TLS configuration, and assess server/infrastructure exposure such as open ports and exposed services. Session management, authentication, and authorization flows will be verified for weaknesses that enable privilege escalation or account takeover. Testing will be non-destructive and fully pre-approved for any action that could impact availability or data integrity. NDA compliance and clear professional English communication are built into the process.

@jonasdedzo

Hello, I think you are trying to get a complete security picture of your web application before any real-world threats can impact your users or business. I can help perform a controlled penetration test covering application logic, authentication flows, APIs, user roles, server configuration, and OWASP Top 10 vulnerabilities. I will start by understanding the application structure and access points, then perform both automated scanning and manual testing using security testing methods to identify weaknesses such as injection issues, access control problems, session flaws, and configuration risks. After testing, I’ll provide a clear report with severity levels, reproduction steps, and practical remediation recommendations that your technical team can easily follow. My focus will be finding real security risks without causing disruption, while giving you actionable insights to strengthen the application. Looking forward to work with you. Thanks

Your requirement for controlled black-box/grey-box testing across login flows, APIs, user roles, admin panels, and infrastructure should be handled as a combined manual assessment and automated scan, not as a tool-generated report alone. I would begin with written scope, authorised targets, test accounts, rate limits, and rules of engagement, then assess OWASP Top 10 risks, broken access control, IDOR, session handling, authentication, CSRF, injection, XSS, API exposure, business-logic flaws, SSL/TLS, open ports, outdated services, and security misconfigurations. The two priorities would be clean implementation and maintainability, with every confirmed issue tied to reproducible evidence and remediation your developers can validate. Testing would use tools such as Burp Suite, OWASP ZAP, Nmap, and Nessus or equivalent, supported by manual verification to reduce false positives. Deliverables would include a severity-ranked technical report, reproduction steps, affected components, recommended fixes, and an executive summary suitable for non-technical stakeholders. Estimated timeline: 7 to 10 business days Fixed price: USD 1,000, assuming one production web application, related APIs, and a standard infrastructure footprint. I can sign an NDA and follow non-destructive testing rules. Any stress testing, exploit chaining, or action with downtime or data-loss risk would require written approval first.

@venplura

Hi there! Quick question: are you looking for testing against a specific compliance standard like PCI-DSS or HIPAA, or is this purely vulnerability-focused? Regardless, this is definitely something that I feel confident delivering on, given my past experience. I would love to discuss your project further! Looking forward hearing from you. kind regards, Corné
