That vulnerability your scanner flagged last? It already missed three others. Automated tools were built for speed, not depth. They catch surface-level issues and hand you a report full of findings that look thorough but leave the real risks untouched. Business logic flaws, broken access controls and chained API vulnerabilities are not things a scanner reasons though they require someone who thinks like an attacker and understands how applications are actually built. With 15 years of web application penetration testing experience and both OSCP and OSWE certifications, the vulnerabilities that matter most are exactly what gets found here. ✅ OSCP and OSWE certified with 15 years of hands-on web application penetration testing ✅ API security testing across REST, GraphQL, BOLA, JWT and OAuth attack surfaces ✅ Full OWASP Top 10 coverage using real working exploits, not recycled scan output ✅ Business logic flaws, auth bypasses and access control gaps that no scanner will catch ✅ SaaS, fintech and startup clients across the US, UK, Europe and Australia ✅ Virtual CISO support for SaaS, fintech and AI companies without a full-time security hire ✅ ISO 27001 implementation and ISMS structuring to pass audits and satisfy enterprise buyers ✅ Security questionnaires handled end-to-end so compliance never stalls a deal ✅ Audit-ready policies, procedures and control frameworks beyond checkbox compliance ✅ Hands-on GRC platform work across Vanta, Drata, Secureframe and Thoropass Certifications: ✅ Offensive Security Certified Professional (OSCP) ✅ Certified Ethical Hacker (CEH) ✅ eLearnSecurity Junior Penetration Tester (eJPT) ✅ GIAC Penetration Tester (GPEN) ✅ Offensive Security Web Expert (OSWE) ✅ GIAC Web Application Penetration Tester (GWAPT) ✅ Certified AppSec Practitioner (CAP) ✅ AWS Certified Security – Specialty ✅ Microsoft Certified: Azure Security Engineer Associate Here's the thing: most penetration testing engagements produce the same report. Same ten findings, same scanner, same template. That is not useful to a development team trying to fix real problems, and it is not useful to a business trying to understand real risk. The vulnerabilities that lead to actual breaches live inside application logic, API design and access control architecture. Finding them requires manual testing, genuine attack thinking and an understanding of where developers cut corners under deadline pressure. Web Application Penetration Testing Testing covers the full attack surface authentication, session management, input validation, business logic, access control and injection vulnerabilities mapped across the complete OWASP Top 10. Burp Suite Professional, OWASP ZAP, Nuclei, ffuf, SQLmap and XSStrike are used alongside deep manual testing to find chained vulnerabilities and logic flaws that no automated tool reaches on its own. Scope covers single-page applications in React, Angular and Vue, backend platforms including PHP, Node.js, Python, Java and .NET, and extends into microservices and cloud-native environments across AWS, Azure and GCP. API Security Testing Every REST and GraphQL endpoint gets tested for broken object-level authorisation, excessive data exposure, broken function-level authorisation, mass assignment, JWT vulnerabilities, OAuth misconfigurations and rate-limiting bypasses. Testing covers both technical weaknesses and business logic abuse, not just surface HTTP checks that any scanner can run. GraphQL engagements go further into introspection abuse, batching attacks, nested query exploitation and field-level authorisation gaps. Application Security Audit and Vulnerability Assessment Every audit combines manual penetration testing with SAST via Semgrep, SCA via Snyk and container scanning via Trivy to deliver a full picture of code-level, dependency and infrastructure risk. Findings are prioritised by real exploitability and business impact, not by CVSS score alone. Compliance-Aligned Testing Audit work maps directly to OWASP ASVS, SOC 2, GDPR and NIST CSF requirements — useful for SaaS companies approaching enterprise sales, startups preparing for investor due diligence and platforms handling regulated or sensitive user data. All findings are documented with detailed technical evidence, including proof-of-concept exploitation steps, affected endpoints, request/response analysis, and attack flow breakdowns where applicable. The reporting structure is designed to support engineering teams in reproducing and fixing issues efficiently, with clear mapping to OWASP Top 10 and relevant security controls. Each vulnerability includes prioritized remediation guidance, validation notes Send a message to discuss scope. A short conversation is all it takes to get started.
