A penetration test report should contain an executive summary that provides a high-level overview of the findings and their impact on the organization. It should contain a detailed description of the methodology followed during the test, including the tools and techniques used. The report should also include an in-depth analysis of vulnerabilities discovered, their severity, and recommended remediation measures, along with any supporting evidence such as screenshots, logs, or exploit scripts. Additional observations or recommendations for improving the security posture of the tested system or network may also be added.
