The AICPA never wrote the words penetration test required into SOC 2. Yet a service organization that walks into a Type II audit without one is almost guaranteed to leave with findings, follow-up questions, or a delayed report. That gap, between what the standard technically demands and what auditors operationally expect, is where most companies trip. This article breaks down the real SOC 2 penetration testing requirements: where they sit in the Trust Services Criteria, what auditors look for during Type I and Type II engagements, how often you should test, and what a good pen test report needs to contain to satisfy your auditor without inflating your budget. Understanding SOC 2 and Its Security Expectations What Is SOC 2? SOC 2 is an attestation framework developed by the American Institute of Certified Public Accountants (AICPA) for service organizations that handle customer data. Unlike a certification, SOC 2 is an opinion: a licensed CPA firm reviews your security controls and issues a report stating whether those controls are designed (Type I) or operating (Type II) effectively. SOC 2 reports are read by enterprise procurement teams, security reviewers, and risk officers. Most B2B SaaS contracts in 2026 require one before signing. What Controls Does SOC 2 Require? Rather than dictating specific technologies, SOC 2 requires that you design and operate controls that demonstrably meet each criterion under the Trust Services Criteria (TSC). That gives you flexibility, and it also gives auditors latitude to ask hard questions. Does SOC 2 Require Penetration Testing? The Official SOC 2 Position on Penetration Testing The phrase penetration test appears in the AICPA’s 2017 Trust Services Criteria publication (with 2022 revisions) inside a single Point of Focus under CC7.1, the Common Criterion that requires entities to use detection and monitoring procedures to identify changes to configurations that introduce new vulnerabilities and susceptibilities to newly discovered vulnerabilities. The Point of Focus suggests management uses a variety of ongoing and separate risk and control evaluations to determine whether controls function. Penetration testing is named as one option. That is the entire textual basis. There is no clause that mandates an annual external pentest, no specification of scope, no required methodology. Short Answer: There Are No Mandatory SOC 2 Pen Test Requirements You can technically obtain a SOC 2 report without a penetration test, provided you can show your auditor that you use alternative evaluations to satisfy CC4.1 (ongoing monitoring) and CC7.1 (vulnerability identification). In practice, almost nobody does this successfully. Long Answer: You Still Need SOC 2 Penetration Testing Auditors view penetration testing as the strongest available evidence that your controls work against a determined adversary, not just on paper. CC4.1 asks the entity to perform ongoing monitoring to ascertain whether internal controls are present and functioning; a pen test is the most direct way to evaluate that. CC6.1 asks whether logical access controls can be bypassed; a pen test answers that question directly. CC7.1 ties this together by requiring you to detect newly introduced vulnerabilities. If you skip pen testing, you carry the burden of proving your alternative evidence is at least as good. That is a steeper hill than most organizations realize. What Auditors Expect During Type I and Type II Engagements A SOC 2 Type I report assesses control design at a single point in time. A Type II report assesses operating effectiveness over a defined audit period, typically six to twelve months. Both increasingly assume a recent penetration test exists. For Type II especially, auditors expect the test to fall within the audit window, with documented remediation of any critical or high findings before the period closes. Auditors rarely refuse a Type II report over a missing pentest outright, but they will issue a finding or qualified opinion if they cannot validate CC4.1 evidence. That qualification will be read by every customer reviewing your report. Most CISOs would rather budget $15,000 for a pentest than try to explain a qualified opinion to a procurement team. What Are the Actual SOC 2 Penetration Testing Requirements? Alignment with Trust Services Criteria A pen test that supports a SOC 2 audit must map its findings to specific criteria. Most reputable pentest firms now produce a Trust Services Criteria mapping appendix that ties identified vulnerabilities back to CC4.1, CC6.1, CC7.1, and where relevant CC7.2 through CC7.4. Without that mapping, your auditor has to do the interpretive work themselves, which typically means a follow-up request and a slower report. Scope Definition Requirements Scope should match your SOC 2 system boundary, not your entire infrastructure. If your audit covers a single SaaS product, its API, and its AWS account, that is what should be tested. Auditors look for evidence that the pen test scope was derived from the system description in your SOC 2 report. A mismatch between the two is one of the most common causes of fieldwork delays. Testing Frequency and Timing Requirements SOC 2 does not specify a frequency. Annual testing has become the de facto standard, with additional testing after material changes to architecture, authentication, or hosting. For organizations on continuous deployment, some auditors now accept a combination of annual deep-dive testing and continuous automated assessment as sufficient coverage, but this should be confirmed with your auditor before you rely on it. Remediation Evidence Requirements Findings without remediation are findings against you. Auditors expect documented remediation plans for every critical and high-severity issue, with closed tickets, retest results, or compensating controls recorded before the audit period ends. A finding sitting open in a backlog at audit time is treated almost identically to a finding that was never addressed. Penetration Testing vs. Vulnerability Scans for SOC 2 Both belong in your control set, but they answer fundamentally different questions. Vulnerability scanning is automated and broad, it identifies known CVEs and misconfigurations across your environment quickly and consistently. Penetration testing is manual and adversarial, it simulates what a real attacker would do with the access and information they can obtain. CC7.1 explicitly references both, and your auditor

The CMMC program turned from advisory framework to binding contract requirement on November 10, 2025, when the DoD’s Title 48 acquisition rule took effect.  That single date changed the market for CMMC advisory services overnight, and the Cyber AB Registered Practitioner credential moved from a useful business card to a genuine signal of competence.  Over 80,000 companies in the Defense Industrial Base now need help interpreting the rule, and the RP is the formal entry-level role in the ecosystem authorized to provide it. This guide explains what a CMMC Registered Practitioner is, how the role fits alongside CCPs, CCAs, RPOs, and C3PAOs, what it takes to earn the designation, and how Organizations Seeking Certification (OSCs) should think about engaging one. What Is a CMMC Registered Practitioner (RP)? A CMMC Registered Practitioner is an individual authorized by the Cyber AB, the official accreditation body for the CMMC ecosystem, to provide non-certified advisory and consulting services to Organizations Seeking Certification.  RPs help defense contractors interpret the CMMC model, scope their environments, build documentation, remediate gaps against NIST SP 800-171, and prepare for the formal assessment they will eventually undergo. The credential exists because the CMMC framework is genuinely dense. CMMC Level 2 maps to all 110 controls in NIST SP 800-171, and Level 3 layers on 24 selected requirements from NIST SP 800-172. Most contractors do not have the in-house expertise to implement these controls cleanly, and the Cyber AB needed a way to identify advisors who had at least demonstrated baseline knowledge of the program. An RP does not perform official assessments. That work is reserved for Certified CMMC Assessors (CCAs) operating under a C3PAO. The RP role is strictly advisory, and the Code of Professional Conduct that every RP must sign makes the boundary explicit. How RPs Fit Into the Broader CMMC Ecosystem The Cyber AB structures the ecosystem into two distinct lanes: consulting and implementation on one side, assessment and certification on the other. RPs sit on the consulting side. CCPs, CCAs, and C3PAOs sit on the assessment side. The two are kept deliberately separate so that no firm can audit work it helped configure, a separation that preserves the integrity of the certification process. Registered Practitioners vs. Certified CMMC Professionals (CCPs) The CCP is a more rigorous credential. CCP candidates must complete formal Cyber AB training delivered by a Licensed Training Provider, pass a commercial background check, and sit a proctored exam administered by CAICO. CCPs can participate in actual assessments as part of a C3PAO assessment team, though they cannot lead them. RPs cannot participate in assessments at all. In practical terms, the RP credential is the right starting point for consultants, MSPs, and internal compliance staff who want to demonstrate baseline CMMC fluency. The CCP is the right credential for professionals planning a career in CMMC assessment work. Registered Practitioners vs. C3PAOs A C3PAO (Certified Third-Party Assessment Organization) is the entity authorized to conduct official Level 2 certification assessments and issue formal CMMC status determinations. Fewer than 100 firms held C3PAO authorization as of early 2026, serving an ecosystem of more than 80,000 contractors. C3PAOs are companies. RPs are individuals. They do completely different jobs: the RP prepares the contractor, the C3PAO certifies them. Important: A C3PAO that helps a client implement controls is barred from later assessing that same client. This is a hard line in the Code of Professional Conduct. If you engage a firm for both readiness and certification work, you will end up paying two different organizations regardless, so plan accordingly from the start. What Does a CMMC Registered Practitioner Do? The work of an RP is the work of getting an organization to the starting line of a formal assessment without surprises. That includes interpreting which CMMC level applies to a given contract, scoping the CUI and FCI environments, identifying gaps against NIST SP 800-171, drafting the System Security Plan (SSP) and Plan of Action and Milestones (POA&M), advising on technical remediation, and coaching the OSC through mock assessments before the real one. Who Can a CMMC RP Help? RPs serve any organization in the Defense Industrial Base that needs to achieve a CMMC status. That includes prime contractors, subcontractors at any tier, MSPs, and MSSPs that handle CUI on behalf of defense clients, manufacturers, research universities, and civilian agency contractors whose departments have adopted CMMC-aligned clauses. The flow-down requirements in 32 CFR §170.23 mean that even small subcontractors who process Federal Contract Information (FCI) must hit Level 1, which keeps RP work relevant well past the first wave of large primes. What Services Does a CMMC RP Provide? The core service menu looks consistent across the market: gap assessments against NIST SP 800-171, scope definition, SSP and POA&M drafting, policy and procedure development, technical advisory on encryption, access control and incident response, and pre-assessment readiness reviews. Strong RPs also help clients interpret recent guidance changes, manage their SPRS score, and prepare evidence packages that will survive scrutiny from a C3PAO assessment team. Pro Tip: Evaluating a Registered Practitioner When evaluating an RP, ask whether they have walked a client through a full C3PAO assessment cycle, not just a gap assessment. There is a significant difference between consultants who write SSPs and consultants who have watched assessors actually challenge one. How to Become a CMMC Registered Practitioner The path is straightforward but not trivial. The Cyber AB controls the registration process end-to-end, and every step must be completed in order. Step 1: Complete the Required CMMC Registered Practitioner Training The RP training is delivered online through the Cyber AB’s learning management system. It covers the CMMC model document, the structure of the ecosystem, scoping methodology, FCI and CUI definitions, prime and subcontractor information flow, the assessment process, and the relationship between CMMC and existing DFARS clauses. The course typically takes around eight hours. Candidates should plan for roughly $500 to $600 in combined training and annual registration costs. Step 2: Register with the Cyber AB After training, candidates submit a
