Pentest reports in plain English
When a home inspector examines a house, you receive a written report afterward. It lists the defects found, how urgent they are, and what the repairs will involve. The pentest report is that inspection report for your IT. It is what remains after a penetration test – and the basis for everything that happens next.
A good report speaks to two audiences. Management needs a clear picture within a few minutes: Where do we stand on security, and where do we need to act? The IT team, on the other hand, needs every technical detail to close the gaps. That’s why a pentest report usually consists of a short section in plain language for leadership and a detailed technical section for the specialists.
How a pentest report is structured
Structure and terminology vary from provider to provider. But the following elements belong in every meaningful report:
- Executive summary: The executive summary – sometimes called a management summary – sums up the results without jargon: overall impression, the most important risks, and the most urgent measures.
- Scope and framework: Which systems were tested, over what period, and with or without credentials? What was explicitly excluded? This section on the scope prevents anyone from reading more into the report than was actually tested.
- Approach: A brief description of the methodology and the standards the testing team followed.
- Findings: Each vulnerability is described individually – with the affected system, evidence (such as screenshots or recorded requests), and the steps needed to reproduce the finding.
- Risk rating: Each finding receives a rating, often based on CVSS. This open standard rates severity on a scale from 0.0 to 10.0. Good reports add what the finding specifically means for your organization.
- Remediation recommendations: Every finding comes with a specific recommendation. Not “improve security,” but, for example, “install the update, disable the default account, restrict access to the management network.”
Many reports also note what worked well – such as a protective measure that stopped an attack. That’s valuable too, because it shows which investments have paid off.
A practical example
A fictional scenario: A tax advisory firm has its internal network tested. The executive summary fits on a single page. It attests to an environment that is well maintained overall but warns of an outdated remote maintenance connection. Through it, attackers could reach client data. The firm’s management immediately understands why this item takes priority and approves the budget to replace it.
Meanwhile, the firm’s IT service provider works through the technical findings. Thanks to the documented steps, it can reproduce each finding itself and verify its own fixes. After the retest, the remediated state is confirmed – and the firm can show its clients that it has had its systems tested.
Why does this matter for businesses?
A test is only as good as its report. If the report is vague or hard to understand, the results fizzle out and the gaps stay open. A clear report, on the other hand, makes risks tangible and helps you allocate budget and staff sensibly.
At the same time, the report is important evidence. Many regulations call for the effectiveness of security measures to be reviewed regularly – such as Art. 32 of the GDPR or the ISO/IEC 27001 standard. That’s why auditors, customers, and insurers often ask for documented results.
One more important point: a pentest report is highly sensitive. It describes where and how your organization can be attacked. In the wrong hands, it becomes a playbook for attackers.
What to look out for
- An understandable summary: Can your management understand the executive summary without IT knowledge?
- Reproducible findings: Can every finding be reproduced based on the description and the evidence?
- A well-founded rating: Is the rating related to your organization – and not just a number?
- Specific measures: Does every finding include an actionable recommendation instead of generic advice?
- Verified results: Raw scanner output is not a report. False positives should be weeded out by hand.
- Secure handling: Have the report sent to you encrypted, and limit the circle of readers.
How Rootsektor can help
Our reports are written for both management and technical teams: the executive summary puts the results into context for management, while the technical part provides evidence, a CVSS rating, and a specific remediation recommendation for each finding. We don’t wait for the report to flag critical vulnerabilities – we report them immediately, while the test is still running, to your agreed contact person. You also receive a test certificate that you can use to demonstrate the test to customers, partners, insurers, and auditors. You can learn more about our testing on the Penetration Testing page.
