The penetration test report is the main product you’re paying for. It’s the document that should help fix vulnerabilities, justify security investments, and meet compliance requirements. Unfortunately, report quality in the market varies significantly.
This article explains what you should expect from a professional report and how to assess whether you received a valuable deliverable.
Structure of a Professional Report
1. Executive Summary
For whom: Board, CISO, non-technical managers
What it should contain:
- Overall security level assessment (e.g., 1-5 scale or risk rating)
- Key findings in business language
- Critical risks for the organization
- Priority recommendations
- Comparison with previous tests (if applicable)
Length: 1-2 pages
What to avoid:
- Technical jargon
- Exploitation details
- Lists of all findings
Example of good executive summary:
“Penetration testing of application XYZ revealed a high risk level (4/5). Three critical vulnerabilities were identified enabling unauthorized access to customer data. Most urgent is the SQL Injection vulnerability in the login module, which allows extraction of the entire user database. We recommend immediate patch deployment before production launch.”
2. Methodology and Scope
What it should contain:
- Exact description of test scope (what was tested)
- Exclusions (what wasn’t tested and why)
- Applied methodology (OWASP, PTES, NIST)
- Tools used during testing
- Testing dates and times
- Test type (black/grey/white box)
- Limitations (e.g., no production access)
Why it matters:
- Allows understanding findings context
- Enables test repetition
- Protects both parties (scope documentation)
3. Findings (Vulnerabilities)
Each vulnerability should contain:
a) Identifier and Title
- Unique number (e.g., VULN-001)
- Descriptive title (e.g., “SQL Injection in Login Form”)
b) Severity/Risk Rating
- Standard scale (Critical, High, Medium, Low, Informational)
- Rating justification (CVSS score or custom methodology)
- Business context affecting assessment
c) Vulnerability Description
- What the problem is
- Where it occurs (URL, endpoint, function)
- Conditions for occurrence
d) Proof of Concept (PoC)
- Steps to reproduce
- Evidence (screenshots, payloads, logs)
- Sufficient detail for client validation
e) Impact
- What an attacker can achieve
- Impact on CIA (Confidentiality, Integrity, Availability)
- Business consequences
f) Remediation Recommendations
- Specific steps to fix
- Alternative solutions (if primary impossible)
- References to documentation/best practices
g) References
- CWE ID
- OWASP category
- CVE (if applicable)
- Links to documentation
4. Findings Summary
Summary table containing:
- All findings with severity
- Status (new, known, fixed)
- Remediation priority
- Owner (if known)
Visualizations:
- Severity distribution chart
- Trend over time (if recurring tests)
- Breakdown by category (web, infrastructure, config)
5. Technical Appendices
For the technical team:
- Raw scanner data
- Full test logs
- Screenshots and evidence
- List of tested hosts/endpoints
- Testing activity timeline

Quality Signs vs Red Flags
High-Quality Report Characteristics
✅ Customization to environment – findings relate to your specifics ✅ Business context – risk assessment considers your business ✅ Actionable recommendations – you know exactly what to do ✅ Proof of Concept – you can verify findings yourself ✅ Clear structure – easy to find needed information ✅ Consistent terminology – consistent naming and formatting ✅ Current references – links to current documentation
Low-Quality Red Flags
❌ Generic content – descriptions copied from the internet ❌ No PoC – “we found a vulnerability” without proof ❌ Inconsistent ratings – similar problems with different severity ❌ Scanner output only – tool screenshots without analysis ❌ Unrealistic recommendations – “rewrite the entire application” ❌ No context – technical descriptions without business impact ❌ Factual errors – mistakes in system names, dates, versions
How to Evaluate Report Before Acceptance
Acceptance Checklist
Formal:
- Report delivered on time
- Format per contract (PDF, Word, platform access)
- Signed/authorized by provider
- NDA and confidentiality terms met
Substantive:
- Executive summary understandable to non-technical reader
- Scope consistent with SOW
- All in-scope systems were tested
- Findings have PoC enabling verification
- Recommendations are specific and actionable
- Severity ratings are consistent and justified
Technical:
- Ability to reproduce findings by own team
- No false positives (sample validation)
- Discoveries make sense in environment context
- References are current and correct
What to Do When Report Doesn’t Meet Expectations
Step 1: Document Issues
Prepare a list of specific concerns:
- Missing elements
- Factual errors
- Unclear items requiring explanation
- SOW inconsistencies
Step 2: Communication with Provider
Professional providers expect feedback and corrections. Send:
- List of concerns
- Request for correction/supplement
- Deadline for fixes
Step 3: Escalation (if needed)
If provider refuses corrections:
- Refer to contract (SLA, deliverables definition)
- Escalate to provider’s management
- Consider withholding final payment
Step 4: Documentation for Future
Regardless of outcome:
- Record lessons learned
- Update vendor selection criteria
- Refine requirements in future SOW
Maximizing Report Value
Results Presentation
Request a walkthrough meeting:
- Presentation for management (executive level)
- Technical session for IT/Dev team
- Q&A with pentesters
Remediation Prioritization
Create a remediation plan:
- Critical: immediately (days)
- High: in nearest sprint (weeks)
- Medium: in backlog (months)
- Low: with other changes
Retest
Plan fix validation:
- Establish retest scope
- Set timeline after patch deployment
- Budget retest (often additional cost)
Archiving and Trending
- Store reports securely
- Compare results between tests
- Track metrics: number of findings, MTTR, recurring issues
Report Formats
Traditional PDF
Pros: Formal, easy to archive, compliance-friendly Cons: Static, difficult to track remediation
Online Platform
Pros: Real-time updates, ticket integration, dashboards Cons: Provider dependency, confidentiality concerns
Hybrid
Best of both worlds:
- Formal PDF as official deliverable
- Platform access for ongoing management
- Export to own systems (SIEM, ticketing)
Summary
A professional pentest report includes:
- Executive Summary – for management, in business language
- Detailed findings – with PoC, impact, and recommendations
- Actionable insights – you know what and how to fix
- Documentation – methodology, scope, limitations
Don’t accept reports that:
- Are mainly scanner output
- Have no proof-of-concept
- Contain generic content unrelated to your environment
- Don’t provide specific remediation steps
The report is the main deliverable – you have the right to expect quality.

The part of the report to read first
Most readers start with the findings. The section that tells you whether the findings are worth anything comes earlier: the scope and methodology statement. It records what was in scope, what was excluded, from which starting point the work was performed and how many days it took. A report with an impressive finding list and a vague scope statement usually describes a scan of whatever answered on the network that week.
Agreeing that statement before the work starts, rather than reading it afterwards, is how penetration testing is set up.

Frequently asked questions
What should a professional penetration test report contain?
A professional pentest report should contain an executive summary presenting findings in business risk terms accessible to non-technical leadership, a technical summary with overall scope, methodology, and key statistics, detailed findings for each discovered vulnerability including description, evidence, severity rating, reproduction steps, and specific remediation recommendations, and appendices with supporting technical data. The report must distinguish clearly between what was in scope versus what was actually tested.
How should vulnerability severity be rated in a pentest report?
Severity should be rated using a recognized framework such as CVSS (Common Vulnerability Scoring System) combined with contextual business impact assessment. A technically critical vulnerability in an isolated test system may be lower business priority than a medium-severity finding on a payment processing system. Reports should clearly explain both the technical severity score and the practical business risk considering exploitability in the specific client environment, asset criticality, and available compensating controls.
What are the warning signs of a low-quality penetration test report?
Warning signs include findings that consist entirely of automated scanner output without evidence of manual verification, generic remediation advice that does not reference the specific system or technology in use, CVSS scores without contextual business risk explanation, absence of attack chains demonstrating how multiple findings could be combined, and lack of screenshot evidence or reproduction steps. A good report should clearly show that a human expert analyzed the environment rather than simply running automated tools and formatting the output.
How should organizations manage remediation after receiving a pentest report?
Organizations should assign a named owner to each finding immediately after receiving the report, prioritize remediation by risk level and exploitability, establish a remediation timeline with specific deadlines for critical and high findings, track progress in a vulnerability management system rather than spreadsheets, request a verification test from the same pentest team to confirm critical findings are truly fixed, and share remediation progress with senior management through regular status updates. The remediation process is where the actual security improvement happens, making it as important as the pentest itself.
