Penetration Testing Methodology Comparison: PTES vs OSSTMM vs NIST vs OWASP cho Doanh nghiệp Việt Nam

Multiple penetration testing methodologies guide how assessments are conducted: PTES (Penetration Testing Execution Standard) provides a comprehensive seven-phase approach; OSSTMM (Open Source Security Testing Methodology Manual) emphasises operational security metrics; NIST SP 800-115 provides technical guidance for government systems; and OWASP Testing Guide focuses specifically on web applications. Our methodology incorporates elements from each, tailored to the specific engagement — because no single framework covers every scenario adequately.
