CMMC Compliance in Alpharetta, GA

CMMC Compliance Services for Alpharetta, GA Businesses

If your Alpharetta company holds, processes, or transmits Controlled Unclassified Information (CUI) for a federal agency or Department of Defense contractor, you are subject to the Cybersecurity Maturity Model Certification (CMMC) 2.0 framework. Under CMMC 2.0, contracts at Level 2 require alignment with all 110 practices in NIST SP 800-171, and third-party assessment organizations (C3PAOs) will verify that alignment before you can bid or retain DoD work. COMNEXIA, headquartered in Roswell, GA since 1991, helps Alpharetta-area organizations map their current environment to those 110 controls, close the gaps, and maintain the documented evidence that auditors require.

What CMMC 2.0 Actually Requires from Your IT Environment

CMMC Level 2 maps directly to NIST SP 800-171 control families including Access Control (AC), Incident Response (IR), System and Communications Protection (SC), and Configuration Management (CM). These are not checkbox items. Access Control, for example, requires enforced least-privilege, multi-factor authentication for all remote and privileged access, and documented session-termination policies. COMNEXIA implements those controls using Microsoft Entra ID conditional access policies that block legacy authentication protocols, enforce phishing-resistant MFA (Microsoft Authenticator or FIDO2 keys), and restrict access by device compliance state. This is a named configuration your auditor can verify in the Entra ID portal, not a general statement about "strong authentication."

Incident Response under NIST 800-171 requires a written IR plan, defined roles, tested procedures, and the ability to detect and contain incidents within a documented timeframe. COMNEXIA addresses this through 24/7 SOC monitoring backed by SentinelOne EDR deployed on every endpoint. SentinelOne's Singularity platform provides real-time behavioral detection, automated threat containment (Storyline-based rollback), and forensic telemetry that satisfies the audit trail requirements in IR.3.098 through IR.3.102.

The Controls COMNEXIA Configures for CMMC Readiness

• Endpoint Detection and Response: SentinelOne EDR deployed and policy-locked on every workstation and server, replacing or layering over native AV to satisfy Media Protection and System Integrity controls.
• Identity and Access Management: Microsoft Entra ID conditional access with MFA enforcement, named-user accounts for all CUI-system access, and Privileged Identity Management (PIM) for admin roles, satisfying AC.1.001 through AC.2.006.
• Cloud Security Posture: Microsoft Defender for Cloud configured to assess your Azure or Microsoft 365 tenant against the NIST 800-171 regulatory compliance benchmark, producing scored control reports you can hand to a C3PAO assessor.
• Patch and Configuration Management: NinjaOne RMM enforcing monthly OS and third-party patch cycles, with documented patch reports retained for six months to satisfy CM.2.061 and CM.3.068.
• Backup and Data Protection: Immutable, off-site backups following the 3-2-1 rule (three copies, two media types, one off-site), with tested restore procedures documented to satisfy Media Protection controls requiring CUI recoverability.
• Security Awareness Training: Quarterly phishing simulations and role-based training targeting CUI-handling employees, satisfying Awareness and Training controls AT.2.056 and AT.3.058.
• System Security Plan (SSP) and Plan of Action and Milestones (POA&M): COMNEXIA produces and maintains the SSP and POA&M documentation that CMMC assessors review, including your CUI boundary diagram, asset inventory, and control narratives.

Alpharetta Automotive Dealerships: CMMC Meets FTC Safeguards

Alpharetta's North Point corridor includes several high-volume franchise dealerships whose F&I departments interact with lenders and service departments that may touch government fleet or GSA contracts. These dealerships already face FTC Safeguards Rule (16 CFR Part 314) requirements covering their DMS platforms (CDK Global, Reynolds and Reynolds, Dealertrack). COMNEXIA's CMMC readiness work overlaps substantially with Safeguards compliance: the MFA enforcement in Microsoft Entra ID, the SentinelOne EDR deployment, the patch cadence in NinjaOne, and the written incident response plan satisfy obligations under both frameworks simultaneously. If your dealership holds or may hold fleet contracts with federal agencies, COMNEXIA will assess whether your CDK or Reynolds environment creates a CUI boundary and document it accordingly, rather than leaving that question open for an auditor to resolve against you.

How COMNEXIA's Engagement Works

COMNEXIA begins every CMMC engagement with a gap assessment against all 110 NIST 800-171 practices, scored against your current environment using documented evidence rather than verbal attestation. You receive a written gap report with prioritized remediation steps, effort estimates, and a draft POA&M within 30 days. Remediation follows a defined project plan, with each control closure documented in your SSP. After remediation, COMNEXIA provides monthly reporting through NinjaOne dashboards and Microsoft Defender for Cloud compliance scores so your SPRS (Supplier Performance Risk System) self-assessment score reflects your real posture. We are not a certification body and do not grant CMMC certificates, but we prepare your environment and documentation so that when a C3PAO assessor arrives, your evidence package is complete.
