Penetration Test Attestation Reports

Why Attestation Documentation Matters

A penetration test report serves two audiences with different needs: your technical team needs granular findings and remediation guidance, while your auditors, clients, and regulators need confirmation that testing occurred, what it covered, and what the outcome was. Attestation documentation bridges that gap, providing compliance-ready evidence without exposing sensitive technical findings to audiences who don't need them.

What Grid32 Provides After Every Engagement

Every Grid32 engagement delivers a tiered documentation package:

• Executive Summary: A two to three page non-technical overview of scope, methodology, overall findings, and risk posture. Suitable for board presentations, CISO reporting, and auditor review without disclosing exploitable details.
• Detailed Technical Report: The complete findings document: every vulnerability, evidence of exploitation, severity rating, affected systems, and step-by-step remediation guidance. For your CISO, IT team, and security engineers.
• Attestation Letter: A signed letter on Grid32 letterhead confirming the scope, dates, methodology, and overall outcome. Formatted specifically for auditors, regulators, clients, and cyber insurers who need to confirm testing occurred without receiving the full technical report.
• Client-Facing Summary: A condensed, business-language summary suitable for sharing with customers who ask for evidence of your security testing program.

Using Attestation Documentation for Specific Frameworks

• NYDFS: The attestation letter and executive summary support the annual compliance certification. The detailed report supports examiner requests for penetration test documentation.
• SOC 2: The attestation letter and executive summary integrate directly into the audit evidence package. The detailed report is available to auditors under NDA.
• PCI DSS: The complete report including segmentation test results satisfies Requirement 11.4 documentation requirements. Your QSA receives the full technical report.
• Cyber Insurance: The attestation letter confirms annual testing for carriers who require evidence of it at renewal.

How Auditors and Third Parties Use Your Attestation

An attestation letter exists so you can prove testing without exposing your vulnerabilities. Auditors and QSAs accept it as evidence that independent testing occurred within the required window; cyber insurers use it at application and renewal; and enterprise customers accept it in vendor security reviews. Because it confirms scope, date, independence, and remediation without listing findings, you can share it freely where handing over the full technical report would be inappropriate. Grid32 produces it alongside the technical report from every engagement.

Frequently Asked Questions

What is a penetration test attestation report?

An attestation report is a concise, client-facing document confirming that an independent firm performed a penetration test, when it occurred, what was in scope, and that findings were addressed. It lets you demonstrate compliance to auditors, regulators, insurers, and customers without exposing sensitive technical detail.

What does Grid32 provide after an engagement?

Every Grid32 engagement includes a detailed technical report for your team and a clean attestation letter for third parties. Remediation verification is available so the attestation can state that identified issues were retested and resolved.

Who accepts attestation documentation?

Auditors and QSAs, cyber insurance underwriters, regulators such as NYDFS, and enterprise customers running vendor security reviews all accept attestation documentation as evidence that current, independent penetration testing was performed.
