CMMC Penetration Testing

Why it matters

CMMC compliance is now a contract-eligibility gate for the defense industrial base — losing certification means losing eligibility for DoD contracts, and once a C3PAO assessment is scheduled, the window for remediation closes fast. Going in with current, documented testing evidence and a clean SSP/POA&M is the difference between a smooth assessment and a costly one.

What we test

• CUI enclave & connected-system penetration testing
• NIST 800-171 control gap analysis
• Vulnerability scanning & assessment (RA.L2-3.11.2 evidence)
• Access control & least-privilege testing
• Incident response readiness validation
• SSP / POA&M evidence preparation

Common vulnerabilities we uncover

• CUI reachable through an inadequately scoped enclave boundary
• Missing or outdated System Security Plan documentation
• Unassessed subcontractor or supply-chain access to CUI
• No documented vulnerability scanning cadence
• An incident response plan that has never been tested
• Findings with no evidence structured for a C3PAO assessor

Our methodology

1. Scoping & rules of engagement. We agree objectives, targets and boundaries for your cmmc penetration testing, so testing is safe, authorized and focused on what matters to your business.
2. Reconnaissance & mapping. We enumerate the full attack surface in scope, building a complete picture before any exploitation begins.
3. Manual exploitation. Our senior testers chain vulnerabilities by hand — going far beyond automated scanners — to prove real, demonstrable impact.
4. Analysis & reporting. Every finding is triaged, risk-rated with CVSS and written up with a copy-paste reproduction and clear remediation.
5. Remediation support & free retest. We support your team through the fixes and retest the remediated issues to confirm they are genuinely closed.

Tools & techniques

We test the CUI enclave and connected systems by hand, mapped explicitly to NIST 800-171 control families — access control, incident response, risk assessment, and system and communications protection — and structure every finding to feed directly into your SSP and POA&M rather than sitting as a standalone technical report.

When you need this engagement

• You are a DoD contractor or subcontractor handling CUI
• You are preparing for a CMMC Level 2 C3PAO assessment
• Your SSP or POA&M needs current technical testing evidence
• You are a subcontractor being asked to prove compliance by a prime
• You have self-attested but never had independent, manual validation

What you receive

• NIST 800-171 control gap analysis
• Manual penetration test report across the CUI enclave
• SSP & POA&M supporting evidence
• Vulnerability scanning & assessment documentation
• Prioritised, assessment-ready remediation roadmap
• Free retest before your assessment window

What’s included in your report

Every cmmc penetration testing engagement concludes with a comprehensive, board-ready report and a working session to walk your team through it. Your report includes:

• An executive summary with overall risk posture for non-technical stakeholders
• Detailed technical findings, each with a step-by-step, copy-paste reproduction
• CVSS v3.1 severity ratings and business-impact context for every issue
• Prioritized, actionable remediation guidance your engineers can apply directly
• A complimentary retest to confirm fixes and update finding status
• A formal attestation letter for customers, auditors and compliance programs

Standards & frameworks

Outcomes you can expect

After your cmmc penetration testing, you will have clear, evidence-based visibility into your real security risk — not a scanner’s guesswork. You will know exactly which weaknesses an attacker could exploit, what the business impact would be, and the precise steps to fix them in priority order. Teams use our findings to close critical gaps, satisfy customer and regulator security requirements, and demonstrate due diligence to their board. With a complimentary retest included, you also get documented proof that the issues are genuinely resolved.

Engagement details & logistics

Every cmmc penetration testing starts with a short, no-obligation scoping call to understand your goals, environment and constraints, followed by a fixed-price proposal and a clear statement of work. Most engagements are delivered fully remotely, with on-site work arranged where it genuinely adds value. Throughout testing we maintain an agreed communication cadence and escalate any critical, high-impact finding to you immediately rather than waiting for the final report. All work is performed under a signed NDA with strict data-handling controls, using safe, non-disruptive techniques and carefully coordinated rules of engagement to protect your production systems. On completion you receive your report and a walkthrough session, followed by a complimentary retest once your fixes are in place. Typical engagements are booked one to three weeks in advance, and urgent or pre-deadline testing can often be accommodated — just ask at hi@agentoffense.com.

Why organizations choose AgentOffense

Our cmmc penetration testing is delivered by senior offensive-security engineers who test the way real attackers do — manually, creatively and with a relentless focus on proving genuine, demonstrable impact. Here is what sets our engagements apart:

• Manual, exploit-driven testing that chains vulnerabilities the way a real attacker would, going far beyond what automated scanners can find.
• Reproducible proof for every finding, with copy-paste reproduction steps your engineers can follow and independently verify.
• Honest severity calibration so you invest in fixing what genuinely matters and avoid wasting effort on false positives and noise.
• Clear, business-focused reporting that speaks to engineers and executives alike, tying every issue to real-world impact.
• A complimentary retest included, so you get documented proof that your fixes actually close the attack path.
• Responsible, collaborative delivery with a named point of contact and secure handling of all data throughout the engagement.

How much does CMMC Penetration Testing cost?

Every cmmc penetration testing is scoped and priced individually, so you pay for exactly the coverage you need — with no hidden extras. After a short, no-obligation scoping call we send a fixed-price quote, usually within one business day, with clear deliverables, a firm timeline and a complimentary retest included. The price of your cmmc penetration testing depends on the size and complexity of the target and the depth of testing required, so you always know the cost up front before any work begins.
