What a Penetration Test Report Should Include for Your Cyber Insurer

Cyber insurers in 2026 no longer accept “We’re secure, trust us” on a checkbox questionnaire. They want evidence. A penetration test report is now one of the primary documents underwriters and claims teams use to decide whether to insure you, what to charge, and whether to pay when things go sideways.

If you are a Montana healthcare organization, law firm, or business, the quality of your next pentest report can directly affect your insurability, your premiums, and how your carrier treats you after a breach.

Key points

• Insurers now use pentest reports for underwriting and post‑incident claim validation.
• A carrier friendly report includes at least seven sections: scope, methodology, tools, findings by severity, PoCs, remediation guidance, and an executive summary.
• Reports should map findings to NIST / ISO / OWASP and to specific cyber insurance control questions.
• Most carriers expect reports from the last 12 months, so schedule testing 60–90 days before renewal to leave time for fixes.
• Scan only reports, no severity ratings, and no remediation dates are red flags that frustrate underwriters and claim examiners.

Why cyber insurers care so much about your pentest report

Insurers have taken heavy losses on cyber claims in the last few years, so they have “hardened” the market. They no longer trust self‑attested questionnaires without proof. Your pentest report matters in two moments:

1. Underwriting and renewal
   • Underwriters use the report to assess your true risk posture, understand your external and internal weaknesses, and verify controls like MFA, segmentation, and incident response are real, not just policies.
   • Strong, recent testing can improve eligibility and often helps with more favorable terms.
2. Post‑breach claim validation
   • When you file a claim, carriers may review past pentest reports to see if you knew about issues and what you did about them.
   • If a breach exploits a critical vulnerability that was documented and never addressed, expect tougher questions and possible coverage disputes.

For Montana organizations, that means a pentest report is not just internal security documentation. It is part of your financial defense when a cyber crisis hits.

Seven must have sections in a carrier ready pentest report

A “good enough” report for cyber insurance almost always includes the following seven sections.

1. Scope and objectives
   • Clear list of in scope systems, networks, applications, and environments.
   • Testing dates, locations, and whether the engagement was external, internal, web app, cloud, or hybrid.
   • This lets carriers match the report to the assets you list on the insurance application.
2. Methodology
   • High level description of phases: reconnaissance, vulnerability analysis, exploitation, post exploitation, and reporting.
   • Mention of standards like NIST SP 800‑115, OWASP WSTG, or other recognized testing approaches.
3. Tools and techniques used
   • Summary of major tools and frameworks (for example commercial scanners, open‑source tools, custom scripts).
   • Enough detail that an insurer can see the test went beyond a simple vulnerability scan.
4. Findings organized by severity
   • Vulnerabilities listed with severity ratings (for example Critical, High, Medium, Low) and often CVSS scores.
   • Clear impact statements (for example “allows unauthenticated access to PHI,” “permits lateral movement toward domain controllers”).
5. Proof of concept (PoC) evidence
   • Screenshots, logs, or snippets showing how issues were discovered or exploited.
   • Demonstrates to carriers that vulnerabilities are not theoretical and that the test was conducted as described.
6. Remediation guidance and prioritization
   • Concrete recommendations for how to fix each issue, including configuration changes, patches, or architectural improvements.
   • Prioritized remediation plan and, ideally, suggested timelines for each severity level.​
7. Executive summary
   • One to three pages that explain overall risk posture, top issues, and remediation progress in plain language.
   • This is what underwriters, executives, and boards actually read first.

If your existing reports are missing any of these, your insurer may push back or ask for “more detailed documentation” during underwriting or a claim.

Mapping the report to frameworks and your policy questions

Insurers think in frameworks and controls, not tool names. The more your report lines up with their view of the world, the easier your life becomes. Strong reports increasingly:

• Map findings and controls to NIST (for example NIST CSF or SP 800‑115) or ISO 27001 domains.
• Reference OWASP for web and API issues (for example OWASP Top 10 categories or WSTG test cases).​
• Highlight how findings relate to common questionnaire items, such as:
  • MFA on remote access and privileged accounts.
  • Network segmentation between critical systems and user networks.
  • Logging, monitoring, and incident response capability.

For Big Sky Cybersecurity clients, we often align the report to both industry frameworks and a checklist that mirrors what carriers and brokers are actively asking in 2026.

Timing: how old can a report be, and when should you test?

Most carriers only treat pentest reports as relevant if they are recent. Current guidance and broker commentary indicate:

• Underwriters generally want at least one full pentest within the last 12 months.
• For higher risk industries like healthcare and financial services, some carriers prefer 6–12 month cadence.
• If a report is older than 12 months, they may ask for updated testing or detailed evidence of ongoing vulnerability management.

From a practical standpoint, Montana organizations should aim to:

• Schedule penetration testing 60–90 days before renewal.
• Use that window to fix critical issues and, where possible, obtain a short retest report confirming that high‑risk vulnerabilities were remediated.

That way your renewal package shows not just “We found issues,” but “We found them, fixed them, and verified the fix.”

Common report deficiencies that frustrate insurers

We regularly see pentest reports that are fine for internal IT but problematic for insurers. Here are the issues that cause the most friction:

• Scan only deliverables: The “pentest” turns out to be a vulnerability scan with no exploitation, no attack‑path analysis, and little or no human insight.
• No severity or prioritization: Long lists of issues with no risk ratings or guidance on what to fix first. Underwriters have no way to gauge true exposure.
• Missing scope clarity: Reports that do not clearly state what was tested, on what dates, and with what access level.
• No remediation dates or status: No indication of which findings were fixed, accepted, or still open when the report is used for insurance.
• Overly redacted technical detail: Redaction is good security practice, but if you redact too much, the carrier cannot verify that the test was meaningful.

Insurers are not looking for perfection. They are looking for honesty, structure, and progress. A messy report with no prioritization is usually worse than no report at all.

How to share pentest reports securely with brokers and carriers

A penetration test report is sensitive. It tells people exactly how to hurt you. You need to share it, but you need to share it smartly. Best practices include:

• Use secure portals whenever available: Many carriers and brokers now offer encrypted upload portals or secure messaging platforms. Use them instead of email attachments.
• Share the executive summary plus targeted sections: In many cases, you can provide the executive summary, scope, and a list of critical findings and remediation status, instead of the full technical appendix.
• Redact specific exploit details where appropriate: It is reasonable to remove IP addresses, hostnames, and highly sensitive PoC payloads while keeping enough context for underwriters to assess risk.
• Keep a distribution log: Track who has received which version of the report. This matters for both security and legal defensibility.

Big Sky Cybersecurity frequently works directly with brokers to balance insurer visibility with operational security for our Montana clients.

FAQ: Redacted reports, PTaaS, and “bad” findings

Can we send a redacted report to our insurer?

Yes, usually. Most carriers are fine with redacted copies as long as they still include:

• Scope and methodology.
• Severity‑ranked findings.
• Remediation status and dates.

You can often strip out highly sensitive technical detail and PoC payloads. Coordinate with your broker on how much is enough.

Do PTaaS platforms produce acceptable evidence?

They can, but it depends.

Pentesting‑as‑a‑Service (PTaaS) platforms that generate structured reports with clear scope, methodology, severity, and remediation tracking are usually acceptable. If the “report” is just a raw scan dump or a dashboard screenshot, expect questions.

Insurers care more about depth and clarity than whether the work was delivered as a one‑time engagement or via a platform.

What if our report includes really bad findings?

This is where mindset matters. For underwriters, seeing serious issues is not the problem. Seeing serious issues with no remediation plan or progress is the problem. When your report contains critical findings:

• Document what you did, when you did it, and how you validated the fix.
• Be prepared to show a short retest summary or updated screenshots.
• Use the story in your favor: “We discovered X, fixed it within Y days, and changed Z process so it does not happen again.”

Insurers understand that no environment is perfect. They reward organizations that find, fix, and learn.

Turning your pentest report into an asset at renewal time

For many Montana organizations, the penetration test report has been treated as a technical artifact that lives on the IT side of the house. In 2026, it is a business artifact that affects your ability to transfer risk and survive a major incident.

Big Sky Cybersecurity designs penetration testing and vulnerability assessments specifically with cyber insurance and crisis response in mind. Reports are structured so your brokers, carriers, executives, and regulators can all see the same thing: you are serious about finding weaknesses before attackers do and about fixing them quickly when you find them.

If you want your next pentest to support both your insurance renewal and your incident response readiness, schedule a conversation. We will align scope with your policy questions, produce a carrier‑ready report, and stand ready as Montana’s crisis response specialists if you ever have to prove, in the middle of a claim, that you did everything you reasonably could.
