Your report is a roadmap, not a verdict.

The penetration test report is the primary deliverable of the engagement. It is the document that justifies the investment, informs your remediation priorities, satisfies your compliance requirements, and — most importantly — tells you what needs to change to improve your security posture. Yet for many business owners, the report arrives as a dense technical document that feels impenetrable.

It does not need to be this way. A well-written penetration test report should be accessible to both technical and non-technical readers. This article explains how to read yours, what each section means, and how to use it as a tool for action rather than a source of anxiety.

What a good report contains.

While report formats vary between providers, a professional penetration test report should contain the following sections. If your report is missing any of these, it may be worth questioning the thoroughness of the engagement.

Section Audience What It Contains
Executive Summary Board, directors, business owners — non-technical readers A high-level overview of what was tested, the overall risk level, the most significant findings, and strategic recommendations. Typically one to two pages. This is the section you read first and the section you share with your board.
Scope and Methodology All readers What was tested, what was excluded, what testing approach was used, the dates of the engagement, and the methodology followed. This section provides context for the findings and confirms the boundaries of the assessment.
Findings Summary All readers A table or chart showing all findings by severity — critical, high, medium, low, informational. Gives you a quick visual overview of the volume and severity of issues discovered.
Detailed Findings IT team, developers, system administrators Each finding described in detail — what the vulnerability is, where it was found, how the tester exploited it, evidence (screenshots, request/response data), the risk rating and justification, and specific remediation guidance. This is the longest section and the one your technical team will use to fix the issues.
Remediation Recommendations IT team, management Prioritised recommendations for fixing the identified vulnerabilities, often grouped by theme (e.g. 'patch management', 'access control', 'configuration hardening'). May include quick wins and longer-term strategic improvements.
Appendices Technical specialists Detailed technical data — full scan results, tool output, complete evidence chains. Reference material for the technical team working on remediation.

What critical, high, medium, and low actually mean.

Every finding in a penetration test report is assigned a risk rating. Understanding what these ratings mean — and how they should inform your response — is essential for prioritising remediation effectively.

Critical
An actively exploitable vulnerability that could result in complete system compromise, large-scale data breach, or significant business disruption with minimal attacker effort. Examples: unauthenticated remote code execution, default administrator credentials on a public-facing system, SQL injection granting access to the entire database. <strong>Action: Remediate immediately — ideally within 24 to 48 hours.</strong>
High
An exploitable vulnerability that could result in significant compromise, but may require additional conditions — such as authenticated access, user interaction, or chaining with another vulnerability. Examples: privilege escalation from standard user to administrator, stored cross-site scripting in a high-traffic application, weak encryption on sensitive data in transit. <strong>Action: Remediate within one to two weeks.</strong>
Medium
A vulnerability that presents a genuine risk but is harder to exploit, has limited impact, or requires specific conditions. Examples: information disclosure that aids further attacks, missing security headers, session management weaknesses. <strong>Action: Remediate within one to three months, prioritised alongside other security improvements.</strong>
Low / Informational
Minor issues or best-practice recommendations that present minimal direct risk but contribute to overall security hygiene. Examples: verbose error messages, server version disclosure, minor configuration improvements. <strong>Action: Address during routine maintenance cycles or as part of broader hardening efforts.</strong>

Context Matters More Than Individual Ratings

A single medium-severity finding might be unremarkable on its own. But three medium findings that can be chained together — information disclosure that reveals an internal URL, a weak authentication mechanism on that URL, and an access control bypass behind it — may represent a critical attack path. A good penetration test report highlights these chains and explains the combined impact, not just the individual severity of each link.


The section that matters most to you.

As a business owner, the executive summary is your primary tool. It should answer four questions clearly and concisely, without requiring technical knowledge to understand.

Four Questions the Executive Summary Should Answer
1. What was tested?
— Clear description of scope and approach in plain language

2. What is our overall risk level?
— An honest assessment of your security posture
— Comparison to industry norms where possible

3. What are the most serious issues?
— The critical and high findings summarised in business terms
— What an attacker could achieve (not just technical details)

4. What do we need to do?
— Strategic recommendations prioritised by risk and effort
— Clear distinction between urgent fixes and longer-term work

If your executive summary does not answer these questions clearly, ask your provider to revise it. The executive summary exists to inform business decisions — if it reads like a technical appendix, it is not serving its purpose.


What to think when the report arrives.

Receiving a penetration test report can be an uncomfortable experience — particularly if it is your first test or if significant vulnerabilities were found. Some common reactions, and the appropriate perspective on each:

Reaction Perspective
'This is terrible — we have so many findings.' Finding vulnerabilities is the purpose of the test. Every finding is a vulnerability that now has a remediation plan instead of remaining silently exploitable. A report with many findings is not a sign of failure — it is a sign that the tester did their job and you now have actionable information.
'Nothing was found — we must be secure.' A clean report is either genuinely good news (your security posture is strong) or a sign that the test was not thorough enough. Ask your provider: was the scope sufficient? Was enough time allocated? Were all testing approaches used? A clean bill of health from a comprehensive engagement is reassuring. A clean bill from a shallow one is dangerous.
'Our IT team/provider should have caught this.' Penetration testers are specialists who spend their careers finding the vulnerabilities that operational teams miss. Your IT team's job is to build and maintain systems; the tester's job is to break them. These are complementary skills, not competing ones. Use the findings to improve — not to blame.
'We cannot afford to fix all of this.' You do not need to fix everything at once. Prioritise by risk rating — critical and high findings first, then medium, then low. Some findings are quick wins that cost nothing to fix. Others require investment. The report gives you the information to make informed decisions about where to allocate your security budget.

Part 9 preview.

You have the report. Now what? Next week, we cover remediation — how to turn findings into action, prioritise fixes, track progress, and verify that vulnerabilities have been properly resolved. The report is only valuable if it leads to change.


Our reports are written for your whole organisation — not just your IT team.

Every Hedgehog Security report includes a clear executive summary written in plain language, business-context risk ratings, prioritised remediation guidance, and a debrief session where we walk you through the findings and answer your questions face to face.
