CMMC Compliance in Charleston, SC
CMMC Level 1, Level 2, and Level 3 readiness for Charleston-area defense, aerospace, and naval-engineering contractors. Gap assessments, scope reduction, SSP authoring, technical remediation, and C3PAO audit preparation by Petronella Technology Group, a Cyber AB Registered Provider Organization (RPO #1449) headquartered in Raleigh, North Carolina.
ITAR, EAR, and CMMC: The Three-Way Overlap for Charleston Cyber Subs
Charleston cyber-engineering and aerospace subs almost always face three overlapping export and security regimes at once: the International Traffic in Arms Regulations (ITAR) administered by the State Department, the Export Administration Regulations (EAR) administered by Commerce, and the CMMC framework layered on top of DFARS 252.204-7012. The frameworks are not redundant. Each protects a different slice of the same body of technical data, and each carries its own civil and criminal penalty profile. Petronella Technology Group's CMMC engagements always map the three regimes side by side so the Charleston contractor does not pay twice for the same control and does not leave gaps between them.
ITAR Technical Data
ITAR governs defense articles and defense services on the U.S. Munitions List. Charleston defense subs building or supporting weapons systems, naval combat platforms, or military electronics will see ITAR technical data flowing into their environment. ITAR technical data is automatically Controlled Unclassified Information when it touches a DoD contract, which means the same artifact has to satisfy both the ITAR export-control regime and the CMMC protection regime simultaneously.
EAR Dual-Use Technology
EAR governs dual-use commercial and military technology on the Commerce Control List. Many Charleston aerospace and electronics subs operate primarily under EAR rather than ITAR, but specific component drawings, encryption modules, and avionics specifications may still be classified as CUI when associated with a DoD program. Petronella Technology Group helps the Charleston contractor distinguish what is EAR alone, what is ITAR, and what crosses into CMMC scope.
CMMC as the Wrapping Layer
CMMC under 32 CFR Part 170 sits on top of the existing export-control regimes and enforces the technical and procedural controls that protect the data itself. The 110 NIST 800-171 practices govern how the data is stored, transmitted, accessed, monitored, and disposed of. A Charleston sub already running an ITAR-compliant facility has covered much of the physical-security control surface. The remaining work is information-system maturity, identity, monitoring, and the documentation engineering a C3PAO will demand.
Deemed Export and Foreign-National Access
Deemed exports happen when ITAR or EAR controlled technology is shared with a foreign national inside the United States. Charleston subs with international engineering staff, exchange students, or H-1B visa holders need access controls that prevent unauthorized exposure of controlled technology to non-U.S. persons. NIST 800-171 control AC.L2-3.1.1 and AC.L2-3.1.2 line up directly with this obligation, and Petronella's policy set documents both regimes in a single artifact set.
The Charleston Defense, Aerospace, and Naval-Engineering Cluster
Charleston is one of the densest defense ecosystems on the East Coast. Joint Base Charleston anchors a regional supplier base that handles Controlled Unclassified Information across air mobility, naval weapons, aerospace assembly, and command-and-control engineering. Almost every tier of that supplier base must now prove CMMC compliance to keep its contracts.
Joint Base Charleston (JBC)
Joint Base Charleston combines Charleston Air Force Base and Naval Weapons Station Charleston into a single installation. The Air Force side hosts the 437th Airlift Wing and the C-17 Globemaster III mission supporting Air Mobility Command. The Navy side operates as a strategic weapons storage and logistics hub. Suppliers serving either side routinely receive specifications, drawings, and operational data that fall under Covered Defense Information and trigger DFARS 252.204-7012 obligations.
Boeing South Carolina
Boeing's South Carolina campus in North Charleston performs final assembly of the 787 Dreamliner and supports commercial and government aerospace programs. The supplier ecosystem feeding Boeing South Carolina includes composites fabricators, avionics integrators, machine shops, and engineering-services firms across the tri-county region. When those suppliers touch DoD-adjacent specifications or defense-derived aerospace data, they inherit CUI handling obligations and a path toward CMMC Level 2 assessment.
NIWC Atlantic (SPAWAR Successor)
Naval Information Warfare Center Atlantic, in North Charleston, is the Navy's primary C4ISR engineering command on the East Coast. NIWC Atlantic develops, integrates, and sustains command, control, communications, computers, intelligence, surveillance, and reconnaissance systems for the Department of the Navy. Charleston-area contractors supporting NIWC Atlantic build software, hardware, and cybersecurity capabilities that move CUI across the supply chain at every tier.
Port of Charleston and Defense Logistics
The Port of Charleston is one of the busiest container ports in the United States and a critical node in DoD strategic mobility. Logistics, freight-forwarding, and maritime-engineering firms serving defense cargo movements routinely process shipping data, vessel schedules, and routing instructions that qualify as CUI when associated with active military operations. The Charleston Defense Contractors Association supports a growing community of suppliers tracking these obligations.
Deeper Look: How CUI Flows Through Each Cluster
Joint Base Charleston CUI Patterns
The 437th Airlift Wing operates 50+ C-17 Globemaster III aircraft from Charleston AFB, supporting strategic and tactical airlift missions worldwide. Suppliers servicing the C-17 fleet (aircraft maintenance, parts manufacturing, ground-support equipment, mission-planning software) receive technical orders, flight test data, and maintenance specifications that fall under CUI. The Naval Weapons Station side processes ordnance handling procedures, vessel arrival schedules, and storage facility specifications, all of which carry CUI obligations when associated with active operational planning. Each tier of supplier inherits the obligation independently.
Boeing 787 Supply Chain CUI Depth
Boeing South Carolina's North Charleston campus performs final assembly of the 787-8, 787-9, and 787-10 Dreamliner variants. The 787 supply chain stretches across hundreds of tier-2 and tier-3 suppliers including composites fabricators, precision-machine shops, avionics integrators, interior systems vendors, and engineering-services firms. While the commercial 787 itself is not a DoD program, the same Boeing South Carolina supplier base also feeds Boeing Defense, Space & Security programs and supports DoD-derived modifications. When a Charleston-area supplier touches a defense-derived drawing, a government-furnished specification, or a flow-down CUI clause, the entire engineering environment that processes that data falls into CMMC scope.
NIWC Atlantic Engineering Depth
NIWC Atlantic, in North Charleston, is the largest Navy systems-engineering command on the East Coast and a primary node for Department of the Navy C4ISR, cybersecurity, and platform integration work. The command supports surface, subsurface, air, and shore-based Navy and Marine Corps systems including command and control, communications, intelligence, surveillance, reconnaissance, and information operations. Subcontractors supporting NIWC Atlantic build software, hardware, and cybersecurity capabilities that touch CUI at every tier. The supplier base spans large defense primes with Charleston offices, small specialized engineering firms, and an emerging community of cybersecurity boutiques that have grown specifically around the NIWC Atlantic mission.
Charleston Defense Contractors Association
The Charleston Defense Contractors Association is an active local community of defense suppliers serving Joint Base Charleston, NIWC Atlantic, and the broader Lowcountry defense ecosystem. CMMC readiness has become one of the most-discussed topics inside the association as primes flow down DFARS 252.204-7012 and CMMC requirements through their tier-2 and tier-3 supplier networks. Petronella Technology Group's Raleigh-headquartered CMMC practice supports Charleston-area members of that community with the same fixed-fee, fixed-scope engagement model used across the Carolinas defense corridor.
DFARS 7012 and NIST 800-171 for South Carolina Defense Subs
DFARS clause 252.204-7012 has applied to every DoD contractor handling Covered Defense Information since 2017. CMMC under 32 CFR Part 170 (effective December 16, 2024) adds third-party C3PAO assessment to that baseline obligation. Charleston-area subcontractors should treat the two as one continuous compliance program rather than two separate efforts. The clause applies regardless of whether the contractor is a prime, a tier-one supplier, or a sub-tier vendor that only sees CUI through pass-through specifications.
What 252.204-7012 Requires
- Implement the 110 security requirements of NIST SP 800-171 Rev. 2 across every covered contractor information system that processes, stores, or transmits CUI.
- Report cyber incidents affecting Covered Defense Information to DoD via the DIBNet portal within 72 hours of discovery.
- Preserve and protect forensic images of affected systems for at least 90 days so DoD investigators can review the evidence.
- Flow the same protection obligations down to any subcontractor that also receives or generates Covered Defense Information.
What CMMC Adds On Top
- Third-party C3PAO certification of all 110 NIST 800-171 practices for Level 2 contractors with CUI exposure, refreshed every three years.
- Annual affirmation of continued compliance, signed by a senior company official under the False Claims Act risk profile.
- SPRS score posted in the DoD Supplier Performance Risk System on a scale from minus 203 to positive 110.
- Level 3 contractors layer an additional 24 enhanced practices from NIST SP 800-172 for advanced persistent threat resilience.
All Three CMMC Levels for Charleston Contractors
Level 1 (17 practices)
For contractors handling only Federal Contract Information (FCI). Annual self-assessment with SPRS submission. A natural fit for smaller Charleston suppliers, freight-forwarders, and service vendors with limited DoD CUI exposure.
Level 2 (110 controls)
For contractors handling CUI. Triennial C3PAO certification with full SSP, POA&M, and the complete NIST 800-171 body of evidence. The default path for most Charleston defense, aerospace, and NIWC Atlantic subcontractors.
Level 3 (134 controls)
For contractors supporting the most sensitive DoD programs. Adds 24 enhanced controls from NIST SP 800-172 targeting advanced persistent threat resilience, organization-wide threat hunting, and defense-in-depth architecture. Relevant to selected Charleston C4ISR and naval-engineering primes.
Not Sure Which Level?
Your contract specifies it. If the solicitation language is unclear, Petronella Technology Group reads the contract with you during the free initial assessment and maps it to the exact level and scope you have to carry. See our flagship CMMC compliance pillar for the full delivery model across all three levels.
CMMC Level 2 Readiness for Charleston-Area Contractors
Most Charleston-area contractors arriving without an existing 800-171 program need 12 to 18 months from gap assessment to a clean C3PAO Level 2 result. The total investment depends on three variables: the size of the CUI-handling workforce, the maturity of the existing IT environment, and how aggressively the boundary is scoped. Petronella Technology Group quotes every phase as a fixed-fee statement of work after the free initial assessment so there is no open meter and no surprise invoice.
Phase 1: Gap Assessment
From $7,500 for a comprehensive 110-control gap assessment, CUI scoping workshop, and prioritized remediation roadmap. Most Charleston engagements close this phase in 4 to 6 weeks. The deliverable is an SSP outline, a POA&M with owner and milestone assignments, and a SPRS pre-score so leadership knows the exact starting position before a single dollar of remediation work is committed.
Phase 2: Remediation and Documentation
From $35,000 to $150,000 depending on workforce size and the depth of technical remediation required. This phase covers SSP authoring, the 14-family policy set, procedure documents, MFA rollout, logging and SIEM integration, encryption posture, vulnerability management, and CUI-segmented file and identity infrastructure such as Microsoft 365 GCC High or Azure Government. Typical Charleston engagements run 4 to 9 months in this phase.
Phase 3: Mock C3PAO Audit
From $12,500 for a full mock assessment that mirrors the official C3PAO scoring rubric exactly. Petronella's CMMC-RP practitioners walk every control, score each as Met, Not Met, or Partial, and stand up a remediation sprint for any gaps the mock surfaces. Charleston clients typically schedule mock audits 60 to 90 days before the formal C3PAO engagement so corrective work has runway.
Phase 4: Ongoing Maintenance and Affirmation
Custom-scoped retainer (from $30,000 to $90,000 annually) for continuous control monitoring, evidence refresh, POA&M updates, and annual affirmation support. CMMC certification is triennial but the practices must operate continuously, and the annual affirmation is signed under the False Claims Act exposure profile. Petronella Technology Group treats that obligation as a structured engineering discipline, not an annual fire drill.

The 14 NIST 800-171 Control Families a Charleston C3PAO Will Test
Level 2 aligns to the 110 security requirements of NIST SP 800-171 Rev. 2, organized into 14 control families. Petronella Technology Group guides Charleston contractors through each family with documented artifacts, demonstrated practices, and evidence that will survive C3PAO scrutiny. Every control gets a policy that references the requirement, a procedure that implements the policy, and an artifact that proves the procedure actually runs.
Foundation Families
- Access Control (AC): 22 controls governing user authorization, session handling, remote access, and wireless connectivity.
- Identification and Authentication (IA): 11 controls for multifactor authentication, password management, and device identity.
- Audit and Accountability (AU): 9 controls for log generation, retention, review, and protection from tampering.
- Configuration Management (CM): 9 controls for baselines, change control, and least-functionality enforcement.
- Maintenance (MA): 6 controls for safe servicing of in-scope information systems, including remote and offsite work.
- Media Protection (MP): 9 controls for protection, marking, transport, and sanitization of media containing CUI.
- Personnel Security (PS): 2 controls for screening and post-termination access removal.
Program Families
- Awareness and Training (AT): 3 controls for workforce security awareness and role-based training.
- Incident Response (IR): 3 controls including a tested IR plan and 72-hour DIBNet reporting flow.
- Physical Protection (PE): 6 controls for visitor logs, escort, badge access, and protected-area perimeter.
- Risk Assessment (RA): 3 controls including periodic vulnerability scanning and remediation cadence.
- Security Assessment (CA): 4 controls for periodic self-assessment, POA&M maintenance, and continuous monitoring.
- System and Communications Protection (SC): 16 controls for encryption, boundary defense, DNS, and FIPS-validated cryptography.
- System and Information Integrity (SI): 7 controls for flaw remediation, malicious code protection, and security monitoring.
Shrinking the CUI Boundary to Cut Charleston Audit Cost
The single biggest cost lever in a CMMC engagement is the size of the CUI boundary. A Charleston aerospace sub with 400 employees and 30 engineers actually touching CUI does not need 400 people inside a CMMC-scoped environment. A 30-seat CMMC enclave around the in-scope engineers can cut the annual cost of compliance by two-thirds and dramatically shrink the audit footprint a C3PAO has to walk.
The Enclave Approach
- Dedicated Microsoft 365 GCC High tenant or Azure Government landing zone for the CUI-handling workforce only.
- Virtual desktop infrastructure for CUI work, isolating physical endpoints outside the boundary from assessment scope.
- Segmented file shares, SharePoint, and Teams sites with conditional-access policies and data-loss prevention rules.
- FIPS-validated encryption in transit and at rest for every CUI-bearing object inside the enclave.
- Centralized identity provider with conditional access, MFA, privileged access management, and audit log forwarding.
What Stays Out of Scope
- General commercial productivity tools: payroll, HR, marketing, sales CRM, accounting platforms.
- Guest and contractor networks with no CUI routing, isolated behind their own firewall segment.
- Non-CUI engineering data, OEM product literature, and public marketing content.
- Manufacturing-floor operational technology that does not process contract drawings, when properly segmented from the CUI network.
- Personal devices used only for commercial calendar and email, blocked from CUI resources by conditional-access policy.
A common Charleston engagement pattern: a 300-seat aerospace or naval-engineering sub with 25 engineers actively touching CUI ends up with a 25-seat CMMC enclave rather than a 300-seat enterprise certification. The scope reduction typically cuts the annual cost of compliance by two-thirds and dramatically shrinks the audit footprint a C3PAO has to walk during the formal engagement.
The Documentation Your Charleston Assessor Will Ask For
A CMMC assessment is a documentation exercise before it is a technical one. Every control needs a policy that references the control, a procedure that implements the policy, and an artifact that proves the procedure runs. Petronella Technology Group builds and maintains the full body of evidence so the Charleston C3PAO assessor never has to guess.
System Security Plan (SSP)
The SSP describes the system boundary, the 110 controls, and how each is implemented. It references other documents rather than duplicating them. Petronella SSPs read like engineering drawings, not marketing brochures, and are delivered as editable Word documents the Charleston team can maintain after certification.
Plan of Action and Milestones (POA&M)
Every control with a gap gets a POA&M entry with owner, milestone date, evidence link, and closure description. The POA&M is a living artifact, reviewed monthly during the engagement and closed when evidence proves the control is operating to the assessment objective.
14-Family Policy Set
Access control, awareness and training, audit and accountability, configuration management, identification and authentication, incident response, maintenance, media protection, personnel security, physical protection, risk assessment, security assessment, system and communications protection, and system and information integrity. Fourteen policies, one per control family.
Procedure Documents
Each policy references one or more procedures. Procedures describe the actual steps: how to enroll in MFA, how to review audit logs, how to handle an incident, how to onboard and offboard users. These become the artifacts the Charleston team actually uses day to day, not just compliance theater.
Artifact Repository
Screenshots, log excerpts, configuration exports, training records, phishing simulation reports, vulnerability scan reports, patch compliance reports, access reviews, change-management approvals. Each artifact tagged to the specific control it evidences and indexed for assessor walkthrough.
SPRS Submission Package
Supplier Performance Risk System score submission with cryptographic validation. The score ranges from minus 203 to positive 110, where a fully implemented 800-171 environment scores 110. Every missing or partial control costs points. Petronella Technology Group coaches the designated official through the SPRS submission step.
ComplianceArmor: The Tool That Accelerates the Charleston Engagement
Most Charleston contractors do not realize how much of the CMMC engagement is documentation engineering. SSP authoring, POA&M tracking, evidence tagging, control-by-control mapping, and annual affirmation packet assembly together can consume 60 percent of the total engagement hours. Petronella Technology Group built ComplianceArmor as the production tooling that compresses that workload without compromising assessor traceability.
What ComplianceArmor Does
- Generates and maintains the SSP across all 110 NIST 800-171 controls with diff-tracked revisions.
- Tracks POA&M entries with owner, milestone date, evidence link, and closure history per control.
- Tags every artifact (screenshot, log excerpt, config export, training record) to the specific control it evidences.
- Pre-calculates the SPRS score so the designated official knows the posting value before it goes live.
- Assembles the annual affirmation packet with the underlying body of evidence in a single export.
How Charleston Contractors Use It
- Subscription tooling bundled with the Phase 2 remediation engagement so the SSP and POA&M never drift between consulting visits.
- Carries forward into Phase 4 ongoing maintenance so the body of evidence stays current between annual affirmations.
- Available standalone for Charleston organizations already mid-engagement with another consultant who need stronger evidence tooling.
- Reduces engagement hours typically devoted to documentation engineering, freeing CMMC-RP practitioner time for technical remediation and assessor preparation.
ComplianceArmor is a documentation accelerator, not a substitute for the CMMC-RP practitioner work. The platform produces the artifacts. Petronella's human practitioners review every artifact, sign off on the SSP, and stand between the Charleston contractor and the C3PAO assessor. The result is faster delivery without losing the traceability a C3PAO will demand.
AI-Assisted Compliance for Defense Subs
2-minute look at how Petronella's private AI infrastructure accelerates CMMC documentation for Lowcountry defense subs.
C4ISR, Cyber Engineering Subs, and Petronella's Private AI Infrastructure
Naval Information Warfare Center Atlantic is the central node of the Charleston cyber-engineering ecosystem. Subcontractors building C4ISR capabilities, cybersecurity tooling, software-defined networking, and signal-processing systems for NIWC Atlantic handle CUI at every phase of the engineering lifecycle. The same supply chain increasingly relies on AI-augmented compliance workflows, and that is where the data-sovereignty question gets sharp.
What NIWC Atlantic Subs Build
- C4ISR systems engineering, integration, and lifecycle sustainment for Department of the Navy programs.
- Cybersecurity engineering, including boundary defense, identity, and continuous monitoring for naval information networks.
- Software development, DevSecOps pipelines, and software factories supporting fleet readiness.
- Signal-processing, RF, and electronic-warfare research and prototyping for naval applications.
Why Private AI Infrastructure Matters
- CUI does not belong inside a public hyperscaler chatbot endpoint, regardless of how convenient the workflow looks.
- Petronella Technology Group operates an enterprise private AI cluster designed for CUI-aware policy generation, evidence tagging, and control mapping.
- Output throughput per engagement improves significantly, but every artifact still gets a human practitioner sign-off before it lands in the SSP.
- Data sovereignty stays aligned with CMMC, DFARS, HIPAA, and the broader federal data-handling envelope. See AI-augmented compliance for the full architecture.
The Charleston Engagement Model: Remote-First with Onsite Milestones

Charleston CMMC Frequently Asked Questions
What is CMMC and who needs it in Charleston?
The Cybersecurity Maturity Model Certification (CMMC) is the Department of Defense's standard for protecting Federal Contract Information and Controlled Unclassified Information across the Defense Industrial Base. The CMMC Program Rule under 32 CFR Part 170 became effective December 16, 2024. Charleston-area defense, aerospace, and naval-engineering subcontractors handling CUI must achieve Level 2 certification from an accredited C3PAO before award of a covered contract. Subcontractors handling only FCI may qualify for Level 1 self-assessment, and contractors supporting DoD's most sensitive programs may carry the additional Level 3 obligations.
Do you serve Joint Base Charleston suppliers onsite or remote?
Both. Petronella Technology Group runs a hybrid engagement model. Documentation, SSP authoring, technical remediation, and evidence collection happen remotely from our Raleigh, North Carolina headquarters. CUI boundary walks, physical-security inspections, workforce CUI training, incident-response tabletop exercises, and mock C3PAO audits happen onsite at the supplier's Charleston facility. The travel cadence (Raleigh to Charleston is roughly 5 hours by car) is included in every fixed-fee statement of work.
Are Boeing South Carolina subcontractors in scope for CMMC?
It depends on whether the supplier touches DoD-derived specifications. Pure commercial 787 work is governed by commercial export-control and ITAR frameworks rather than CMMC, but when a Boeing South Carolina subcontractor receives DoD-adjacent specifications, defense-program drawings, or government-furnished information, CUI handling obligations apply. Petronella Technology Group reads the flow-down clauses with you during the free initial assessment so you know exactly what scope you have to carry.
What is a realistic CMMC Level 2 timeline for a Charleston-area contractor?
Most Charleston-area contractors without an existing 800-171 program need 12 to 18 months from gap assessment to a clean C3PAO Level 2 result. Contractors who already operate a mature ITAR or NIST CSF program can compress that to 6 to 9 months. The most common cause of delay is CUI boundary disputes inside the company itself; identifying who actually touches CUI is harder than it sounds, particularly inside large aerospace and naval-engineering supply chains.
What does CMMC compliance cost a Charleston contractor?
From $7,500 for the gap assessment, from $35,000 to $150,000 for remediation depending on workforce size and scope complexity, from $12,500 for a mock C3PAO audit, and from $30,000 to $90,000 annually for ongoing maintenance and annual affirmation support on a custom-scoped retainer. Every Charleston engagement is custom-scoped after the free initial assessment because no two CUI environments look the same.
Do you work with NIWC Atlantic C4ISR subcontractors in North Charleston?
Yes. NIWC Atlantic is a primary node in the Charleston cyber-engineering ecosystem, and the subcontractor base supporting it routinely handles CUI across C4ISR systems engineering, cybersecurity tooling, software factories, and signal-processing prototyping. Petronella Technology Group's CMMC practice supports these subs with full SSP and POA&M authoring, technical remediation, and mock C3PAO preparation, plus AI-augmented evidence drafting on our private AI infrastructure so CUI never leaves a sovereign environment.
Can you handle Port of Charleston logistics and freight-forwarding firms?
Yes. Port of Charleston logistics, freight-forwarding, and maritime-engineering firms supporting defense cargo movements process shipping data, vessel schedules, and routing instructions that can qualify as CUI when associated with active military operations. We scope the CUI boundary tightly around those data flows so the broader commercial logistics business stays out of CMMC scope and out of the audit footprint.
Does Petronella Technology Group also support DOE contractors near Savannah River Site?
Yes. The Savannah River Site sits within a few hours of Charleston and supports a network of defense-adjacent contractors handling nuclear materials, environmental remediation data, and DOE-classified information. Many of those contractors carry dual DoD obligations and a CMMC path. Petronella Technology Group consults across both the DoD CMMC envelope and adjacent federal data-handling frameworks for contractors operating across the broader South Carolina defense corridor.
Is your team CMMC certified?
Yes. Petronella Technology Group is a Cyber AB Registered Provider Organization, RPO #1449, verified on the public Cyber AB marketplace. Every consultant on the team holds the CMMC Registered Practitioner (CMMC-RP) credential. Founder Craig Petronella holds CMMC-RP, CCNA, CWNE, Digital Forensics Examiner #604180, and is MIT-Certified in AI and Blockchain. We are a North Carolina firm with statewide reach and a defined Charleston engagement model for South Carolina defense suppliers.
Do you support CMMC Level 3 for advanced Charleston defense programs?
Yes. Level 3 adds 24 enhanced practices from NIST SP 800-172 on top of the 110 Level 2 controls. The enhanced practices target advanced persistent threat resilience and include organization-wide threat hunting, supply-chain risk management, and defense-in-depth architecture requirements. Petronella Technology Group consults on all three CMMC levels (Level 1, Level 2, and Level 3) for South Carolina contractors supporting the most sensitive Charleston-area programs. See our CMMC practice overview for the full delivery model.
How do ITAR and EAR overlap with CMMC for a Charleston cyber sub?
ITAR and EAR are export-control regimes governing what can leave the United States, who can see controlled technology, and how it must be marked. CMMC is the information-security regime governing how the same controlled data is stored, accessed, and monitored on the contractor's own systems. ITAR technical data flowing into a DoD-funded engagement becomes CUI by definition, which means the artifact has to satisfy both regimes at once. Petronella Technology Group maps ITAR, EAR, and NIST 800-171 controls side by side in the SSP so the Charleston cyber sub does not duplicate effort or miss the gaps between the three frameworks.
Does ComplianceArmor work for Charleston organizations not engaged with Petronella for consulting?
Yes. ComplianceArmor is available standalone for Charleston organizations already mid-engagement with another consultant who need stronger documentation tooling. The platform handles SSP generation, POA&M tracking, evidence tagging, SPRS pre-calculation, and the annual affirmation packet. Pricing starts from $497/month. See /compliancearmor/ for the full feature set, or call (919) 348-4912 to discuss bundling with a Phase 2 remediation engagement.
