Penetration testing is conducted by a certified professional (OSCP) who has handled many different projects.

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.

Kozhikode, India - 11:11 am local time
OSCP & CREST-certified Penetration Tester helping SaaS companies, startups, e-commerce platforms, and enterprise teams find real, exploitable security weaknesses before attackers do.

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

✅ Need a professional penetration test or vulnerability assessment for your web application, API, mobile app, network, or infrastructure?

📩 Send me a message, and I will help you define the right scope, testing approach, timeline, and deliverables for your security goals.

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.

Review the work, release payment, and leave feedback to Steffin.
