Should proposal writers include penetration testing results in RFP security sections

Proposal writers should reference penetration testing results in RFP security sections, but rarely share the full report. Provide a summary attestation letter or executive summary confirming a recent test was completed by an independent third party, scope, and remediation status. Full reports contain exploitable details and usually require an NDA before release.

Why Pen Test Evidence Belongs in Security Sections

Enterprise buyers want proof that your security posture has been validated by someone other than your own team. A penetration test—an authorized simulated attack on your systems—is one of the strongest signals you can offer. When an RFP asks about vulnerability management or third-party assessments, citing a recent pen test answers the question directly and builds trust.

Most evaluators aren't looking for raw findings. They want to confirm three things:

• A test happened within an acceptable window (usually the last 12 months)
• An independent firm conducted it, not internal staff
• Critical and high findings were remediated

That's it. Dumping a 60-page technical report into your response actually hurts you—it overwhelms reviewers and exposes your attack surface.

What to Include vs. What to Withhold

The smart move is to share evidence in tiers. Give enough to satisfy the requirement up front, then gate the sensitive material behind controls.

A clean attestation letter from a recognized firm like NCC Group or Bishop Fox carries far more weight than a self-written paragraph. It's third-party validation, which is exactly what buyers are after.

The NDA Question

If a buyer insists on the full report, that's a legitimate request—but it shouldn't happen inside an open RFP submission. Handle it the same way you'd manage any other confidential information request in RFP responses: note that the full report is available under a mutual NDA after shortlisting. This protects you from publishing exploitable details to every losing bidder.

How to Phrase It in Your Response

Keep the language specific and confident. Vague answers like "we take security seriously" get marked down. Compare:

Weak:

We regularly test our systems for vulnerabilities.

Strong:

An independent penetration test of our production environment was completed in Q1 2024 by [firm name], covering external network, web application, and API layers. All critical and high-severity findings were remediated within 30 days. An attestation letter is attached; the full report is available under NDA.

The strong version names the scope, the cadence, the remediation SLA, and the evidence trail. That's what wins points.

Pen Tests vs. Certifications: Use Both

A pen test is a point-in-time check. Certifications prove you run an ongoing program. Buyers usually want evidence of both, so don't treat them as interchangeable.

Pair your pen test attestation with the security certifications enterprise RFPs expect, such as SOC 2 Type II and ISO 27001. When a questionnaire asks about audited controls, your SOC 2 compliance response should reference the pen test as one of the controls auditors reviewed. Likewise, ISO 27001 documentation often requires evidence of regular technical testing under Annex A controls, so the two reinforce each other.

A Practical Layering Approach

1. Lead with certifications — they show maturity and recurring oversight.
2. Back them with a pen test attestation — proof of active technical validation.
3. Offer the full report under NDA — for buyers who escalate to security review.
4. Keep a remediation summary ready — closing the loop on findings is what most teams forget.

Common Mistakes Proposal Writers Make

Most teams get one of these wrong:

• Sharing the full report by default. This leaks your weaknesses and violates your own data handling policy. Don't do it.
• Citing a stale test. A pen test from three years ago signals neglect. If yours is old, schedule a new one before the next major RFP cycle.
• Confusing vulnerability scans with pen tests. Automated scans aren't penetration tests. Buyers know the difference, and misrepresenting it damages credibility.
• No remediation evidence. Reporting findings without showing they were fixed is worse than saying nothing.
• Generic boilerplate. Reusing the same vague security paragraph across every proposal. Maintain a vetted, current answer in your content library instead.

Keep Security Answers Current and Reusable

Security sections appear in nearly every enterprise RFP, so accuracy at scale matters. Store your attestation letters, remediation summaries, and certification references in a managed content library with expiration dates. When a pen test renews, update the source once and every proposal pulls the current version. That discipline also helps reduce proposal turnaround time because writers aren't chasing the security team for the latest evidence on every deadline.

For guidance on independent testing standards, the OWASP Testing Guide is a widely cited reference that many firms scope their tests against—worth naming if your buyer asks about methodology.

Key Takeaways

• Reference, don't dump. Include an attestation letter and remediation summary, not the full report.
• Gate sensitive detail behind an NDA and only after shortlisting.
• Name scope, date, firm, and remediation SLA for maximum credibility.
• Pair pen tests with SOC 2 and ISO 27001 to show both point-in-time and ongoing assurance.
• Keep evidence current in a reusable library so security answers stay accurate across every proposal.

Done right, your penetration testing evidence becomes a trust accelerator—not a liability you accidentally published to competitors.
