Project details
You will get professional penetration testing followed by a report that provides a good outlook on the vulnerabilities and fixes for the same.
Penetration testing is conducted by a certified professional (OSCP) who has handled many different projects. The web app test would be done based on the latest 2021 OWASP Top 10 and Other bugs would also be tested. Manual testing would be preferred over automated scanners as manual testing would produce less network noise and better results.

Security Pen Tester / OWASP Specialist to test web app
Steffin did a great job on our grey-box penetration test. He uncovered several high and critical severity vulnerabilities - including SQL injection and privilege escalation - that we may not have caught otherwise, backed by solid technical evidence. His written report was professional and well-organised, covering findings, risk scores, and specific remediation steps. He also came back for a retest once we'd made fixes, which gave us real confidence that the issues were properly resolved. Clear communicator throughout. Will work with him again.

I provide manual-first penetration testing for Web Applications, APIs, Mobile Apps, Networks, Active Directory environments, Infrastructure, and Thick Client/Desktop Applications. My focus is not just finding vulnerabilities, but validating real-world exploitability, explaining business impact, and giving your developers clear remediation guidance they can actually apply.
🔎 Core services I provide:
• Web Application Penetration Testing
• API Security Testing
• Mobile Application Penetration Testing for Android and iOS
• External Network Penetration Testing
• Internal Network & Active Directory Security Assessment
• Thick Client / Windows Desktop Application Testing
• OWASP Top 10 & OWASP WSTG-Based Security Testing
• Vulnerability Assessment & Manual Validation
• OSINT & External Attack Surface Assessment
• Security Retesting & Remediation Validation
• SOC 2, ISO 27001, PCI DSS, Amazon SP-API, and compliance-oriented pentest reports
📄 What you receive:
• A professional penetration testing report
• Clear proof-of-concept evidence and screenshots
• Technical explanation of each vulnerability
• Business impact written in simple, practical language
• Severity rating and CVSS scoring where applicable
• Step-by-step remediation guidance for developers
• Retest results after your team applies fixes
• Executive summary suitable for management, compliance, vendor review, and internal audit
⚡ My testing approach:
I perform Black Box and Grey Box penetration testing depending on your project requirements. I use a manual-first methodology supported by professional tools such as Burp Suite Pro, but I do not rely only on automated scanners. The goal is to identify security issues that matter in real attack scenarios, including authentication flaws, authorization bypasses, SQL Injection, IDOR, access control issues, business logic vulnerabilities, API security weaknesses, injection flaws, misconfigurations, and sensitive data exposure.
🎯 Best fit if you need:
• A security test before launching a product or major feature
• A web application, API, mobile app, network, or infrastructure assessment
• A compliance-ready report for SOC 2, ISO 27001, PCI DSS, vendor review, or investor due diligence
• Manual security testing focused on real exploitability
• Clear communication with practical remediation advice
• Reliable retesting after fixes are completed
🏆 Certifications and experience:
• OSCP
• OSEP
• OSWP
• CREST CPSA
• Top Rated in Information Security / IT Compliance
• Ranked in the Top 50 in multiple bug bounty programs
• Completed 500+ penetration tests and security assessments
• Available across different time zones
• Open to one-time assessments and long-term security engagements

Steps for completing your project
After purchasing the project, send requirements so Steffin can start the project.
Delivery time starts when Steffin receives requirements from you.
Steffin works on your project following the steps below.
Revisions may occur after the delivery date.
Information Gathering
The first of the seven stages of penetration testing is information gathering. The organization being tested will provide the penetration tester with general information about in-scope targets.
Reconnaissance
The reconnaissance stage is crucial to thorough security testing because the penetration tester can identify additional information that may have been overlooked, unknown, or not provided. OSINT is a big part of reconnaissance.
