Pentesting according to OWASP Testing Guide
The OWASP Web Security Testing Guide (WSTG) is a widely used standard for structured web application security testing. Maintained by OWASP, it focuses strictly on web applications. Other domains such as infrastructure, cloud, or mobile are not covered.
The guide defines clearly structured testing categories, including information gathering, configuration, authentication, authorization, session management, input validation, and business logic. Each category provides objectives, technical background, and practical testing procedures, forming a systematic foundation for identifying common vulnerabilities.
In practice, the WSTG is used as a technical reference to derive test cases and ensure broad coverage. Execution remains critical. The guide provides extensive testing approaches, but does not define clear prioritization or the required depth of exploitation. Exfilion builds on the WSTG as a technical foundation for web application assessments, but deliberately goes further. Instead of purely working through test cases, the focus is on identifying and validating real attack paths. Vulnerabilities are not treated in isolation, but combined and proven through practical exploitation.
The WSTG defines test cases. Real value only emerges through depth and context.
Competence
Exfilion testers deliver proven offensive capability, not theory. Our team consists of experienced hacking experts with hands-on certifications such as
OSCP (Offensive Security Certified Professional),
CRTO (Certified Red Team Operator), and
BACPP (Binsec Academy Certified Pentest Professional).
Together, the Exfilion team combines decades of experience in offensive assessments, red teaming, and deep technical analysis. This experience was built under real-world conditions and not in lab environments.
Pentest Guidelines
Standards are the baseline. Exfilion goes far beyond.
Standards and regulatory frameworks define the minimum. They outline what should be tested, but not how far a real attack can go. They provide structure, but not security.
Many assessments stop where requirements are fulfilled. Checklists are completed and controls are marked as compliant. This is where blind spots emerge, because real attackers do not follow standards, they follow opportunities.
Exfilion uses standards as a starting point, not a boundary. Through experience, technical depth, and creative offensive approaches, we go beyond them to uncover vulnerabilities that remain invisible in conventional assessments.
Your provider for pentest according OWASP Testing Guide
Exfilion stands for deep technical, manual penetration testing at elite level with a clear focus on real attack paths. We do not operate by checklist and not in the style of traditional pentest providers. Our objective is to realistically compromise systems and expose their true attack surface under real conditions. Exfilion is the specialized provider in Germany for penetration test at elite level according OWASP Testing Guide.
