Compliance & GRC Platforms We Support
A few of the popular compliance platforms we work with — among many others.
CMMC 2.0 and NIST 800-171: What Defense Contractors Need to Know
The Cybersecurity Maturity Model Certification 2.0 (CMMC 2.0) became effective November 10, 2025, and it is changing the compliance landscape for every business in the DoD supply chain. CMMC 2.0 establishes three certification levels: Level 1 covers 17 basic safeguarding practices for contractors handling Federal Contract Information (FCI); Level 2 aligns directly with NIST SP 800-171's 110 security controls across 14 families and applies to contractors handling Controlled Unclassified Information (CUI); Level 3 adds NIST SP 800-172 enhanced controls for the most sensitive defense programs. Third-party assessment requirements become mandatory by November 2026, with full enforcement expected by 2028. If you hold DoD contracts today and haven't started your CMMC journey, the window for proactive preparation is closing.
NIST SP 800-171 is the compliance backbone for most government contractors. Its 110 controls span 14 families: 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. DFARS clause 252.204-7012 — included in virtually every DoD contract involving CUI — requires contractors to implement all 110 controls, report cyber incidents to DoD within 72 hours, and maintain a System Security Plan (SSP) documenting how each control is addressed. Contractors must also report their SPRS (Supplier Performance Risk System) score, which is calculated from their SSP assessment. Getting this right requires more than good intentions — it requires an experienced IT partner who understands the control families, knows how to scope CUI properly, and can build a defensible compliance posture.
Sonic Systems works with Southern California defense contractors and subcontractors to navigate CMMC and NIST 800-171 compliance without the chaos. We bring a structured methodology: CUI scoping first, then gap analysis against the 110 controls, then remediation prioritized by risk and deadline. We help clients build SSPs that reflect real controls, not aspirational ones, and POA&Ms that demonstrate genuine progress toward closing gaps. Our compliant cloud architecture work includes Microsoft GCC and GCC High environments — the government-authorized cloud platforms that satisfy FedRAMP and CMMC requirements for CUI handling. Whether you're a first-time government contractor trying to understand what applies to you, or an established subcontractor preparing for your first C3PAO assessment, we have the experience to guide you through.
Who This Is For
- Defense subcontractors handling Controlled Unclassified Information (CUI) for prime contractors or the DoD.
- DoD supply chain companies needing CMMC 2.0 certification to maintain or win government contracts.
- Aerospace and defense manufacturers subject to DFARS 252.204-7012 and ITAR requirements.
- Professional services firms with federal contracts handling sensitive government data.
- Small businesses pursuing their first government contract and navigating compliance for the first time.
Common IT Challenges in This Industry
- CMMC 2.0 certification confusion — understanding which level applies, what assessments are required, and when the deadlines hit.
- NIST SP 800-171's 110 security controls across 14 families feel overwhelming without a structured roadmap and experienced guide.
- CUI scoping is unclear — many contractors don't know exactly which data qualifies as CUI or where it flows through their systems.
- SPRS score requirements: contractors must self-attest a score in the Supplier Performance Risk System, but most don't know how to calculate or document it.
- Cost of compliance for small businesses — implementing 110 controls and maintaining a System Security Plan feels like an enterprise burden.
- Finding IT partners who actually understand CMMC, NIST 800-171, and DFARS — not just general cybersecurity.
What Sonic Systems Delivers for Government Contractor
- CMMC 2.0 readiness assessment — mapping your current environment against the applicable level's requirements and defining the path to certification.
- NIST SP 800-171 gap analysis and remediation across all 14 control families: from Access Control and Audit & Accountability to System & Communications Protection.
- CUI scoping and data flow mapping — identifying exactly what data qualifies as CUI, where it lives, and how it moves through your systems.
- SPRS score preparation and documentation to support accurate self-attestation in the Supplier Performance Risk System.
- System Security Plan (SSP) development — the foundational document that describes your environment, controls, and how you protect CUI.
- Plan of Action & Milestones (POA&M) development — structured remediation tracking that shows auditors your gaps are being addressed.
- Compliant cloud architecture using Microsoft GCC or GCC High — the government cloud environments that meet FedRAMP and CMMC requirements.
- Ongoing monitoring and evidence collection to maintain compliance posture and support third-party assessment when required.
Business Outcomes
- CMMC certification readiness with documentation that supports Level 1, 2, or 3 assessment.
- Accurate SPRS scores backed by documented evidence — no guessing, no inflated self-assessments.
- A completed System Security Plan that satisfies DFARS 252.204-7012 and CMMC requirements.
