An effective penetration test report bridges the gap between cybersecurity findings and actionable business intelligence. The best reports communicate critical vulnerabilities with clarity and precision, serving both technical teams who implement fixes and executives who authorize security initiatives.

Below, I've outlined the essential sections that distinguish a truly valuable penetration test report from a merely adequate one. When evaluating security vendors, ensure their reports transform complex findings into clear security guidance your organization can immediately implement.

Use the following framework to evaluate whether a penetration test report delivers the quality and depth your organization needs:

1. Executive Summary

A strategic overview that distills complex technical findings into business-relevant insights, supported by intuitive visualizations and risk metrics. This section equips leadership to make informed security decisions, facilitates effective communication in stakeholder meetings, and provides auditors or third parties with appropriate context without overwhelming technical detail. Business stakeholders often want to know "what's the bottom line?" and "what should we fix first?".

While some security professionals debate the necessity of an executive summary, I believe in responding to the actual needs of business stakeholders. When leadership requests this overview, it reflects their specific organizational requirements that we should respect.

2. Scope

A definitive outline of what was tested—systems, applications, devices, URLs, and API endpoints—and what was explicitly excluded. This section establishes clear boundaries for the assessment, preventing misunderstandings and providing essential context for all findings. Whether evaluating a single feature or conducting a broad assessment, precise scope documentation protects both parties and ensures aligned expectations.

3. Methodology

A transparent explanation of assessment approach, tailored to the specific environment (web, mobile, API, KIOSK, POS, network) and context (internal/external network).

This section details the testing techniques employed (fuzzing, application mapping, exploitation, static analysis), tools utilized (including custom tools, Burp extensions, specialized libraries), and testing timeline.

By documenting methodology thoroughly, the report establishes credibility, ensures reproducibility, and provides necessary context for interpreting the severity and reliability of identified vulnerabilities.

4. Vulnerabilities

The core of your report—comprehensive and meticulously detailed. For each vulnerability:

• Overall Risk Rating: Quantified assessment using industry standards (CVSS v3.1) or custom methodology
• System / Application / Feature: Precise identification of affected system/application, including specific URLs or endpoints
• Description: Clear explanation of the vulnerability and discovery methodology
• Impact: Business-focused consequences detailing what attackers could accomplish and organizational risk
• Likelihood: Analysis of attack complexity, required privileges, and technical barriers
• Threat Actor Profile (if applicable): Context on what type of adversary could exploit this vulnerability
• Exploitation Status: Confirmation of whether the vulnerability was demonstrated or only detected
• Remediation Steps: Actionable guidance for vulnerability resolution
• References: Links to industry frameworks (OWASP, CWE, MITRE ATT&CK)
• Evidence: Supporting screenshots or logs (appropriately sanitized)

‍

Detailed risk ratings provide crucial context—a critical vulnerability with minimal exploitation likelihood may pose less immediate risk than a moderate vulnerability that's easily exploited. This nuanced assessment enables informed prioritization beyond simple HIGH/MEDIUM/LOW classifications.

5. Appendix or Additional Details

A flexible repository for supplementary information that enhances the report without disrupting its core flow, includes:

• Retest Documentation: Evidence demonstrating vulnerability remediation success
• Compliance Mapping: Correlation of findings to relevant standards (NIST, ISO, PCI-DSS, etc.)
• Threat Narratives: Detailed attack path reconstructions that tell the story of complex exploits, including attempts, successes, and failures
• System-Specific Details: In-depth analysis of complex environments that warrant dedicated attention, organized in structured tables for clarity and reference

‍

Beyond the core sections detailed above, professional penetration test reports should include essential administrative elements: a branded title page with company logo, testing timeline dates, report issuance and revision history, version tracking, and identification of the testing team with their relevant industry certifications. These details establish professionalism, create accountability, and provide critical context for interpreting findings.
