PCI Compliance IT Support in Snellville, GA

PCI Compliance IT Support for Snellville, GA Businesses

If your Snellville business accepts credit or debit card payments, the Payment Card Industry Data Security Standard (PCI DSS) applies to you. Version 4.0 of PCI DSS became the only active standard as of March 31, 2024, raising the bar on encryption, access control, and continuous monitoring. COMNEXIA, headquartered in Roswell, GA since 1991, provides PCI compliance IT support that maps directly to those requirements for businesses across Gwinnett County, including retailers, medical offices, and auto dealerships operating in and around Snellville.

What PCI DSS Actually Requires from Your IT Environment

PCI DSS 4.0 organizes its controls across twelve requirements covering network segmentation, cardholder data protection, vulnerability management, access control, and logging. The standard is not met by signing a self-assessment questionnaire once a year. It requires ongoing technical controls that your IT environment must enforce continuously. Specific gaps that routinely cause Snellville businesses to fail a PCI assessment include unpatched operating systems on point-of-sale endpoints, shared administrator credentials, absent multi-factor authentication on remote access, and flat (unsegmented) networks where card data traffic is visible to general workstations.

How COMNEXIA Addresses Each Control Layer

COMNEXIA builds PCI compliance IT support around named, auditable controls rather than generic promises. Here is what that looks like in practice for a Snellville cardholder environment:

• Endpoint detection and response: COMNEXIA deploys SentinelOne EDR on every endpoint in scope. SentinelOne provides real-time behavioral detection, automated threat rollback, and a tamper-resistant activity log, directly satisfying PCI DSS Requirement 5 (malware protection) and supporting Requirement 10 (audit log integrity).
• Multi-factor authentication and conditional access: Microsoft Entra ID conditional access policies enforce MFA for every remote and administrative login touching cardholder data systems. Policies can restrict access by device compliance state and geographic location, addressing PCI DSS Requirement 8.4 and 8.6.
• Patch management: Using NinjaOne RMM, COMNEXIA automates patch deployment for operating systems and third-party applications across in-scope endpoints, with documented patch cycles and exception reporting delivered in monthly compliance reports. This directly addresses PCI DSS Requirement 6.
• Network segmentation documentation: COMNEXIA maps your cardholder data environment (CDE), documents firewall rules that isolate payment traffic from general business networks, and produces the network diagrams that a Qualified Security Assessor (QSA) will ask to see under Requirement 1.
• 24/7 SOC monitoring: Microsoft Defender for Cloud and SentinelOne feed into a 24/7 SOC that monitors for anomalous activity in your CDE around the clock, satisfying Requirement 10's log review obligations without requiring your staff to manually audit event logs.
• Immutable, off-site backups: COMNEXIA configures a 3-2-1 backup architecture with immutable off-site copies, ensuring cardholder data systems can be restored to a clean state without paying a ransom or losing transaction records required under PCI DSS Requirement 9 and 12.
• Security awareness training with phishing simulation: PCI DSS Requirement 12.6 mandates a formal security awareness program. COMNEXIA delivers recurring phishing simulations and tracked training modules so you have completion records to show an assessor.

Auto Dealerships in Snellville and the FTC Safeguards Rule

Auto dealerships operating in the Snellville and Gwinnett County market face a compliance overlay that most generic IT vendors miss. Dealerships running CDK Global, Reynolds and Reynolds, or Dealertrack as their dealer management system (DMS) process payment card data AND non-public personal financial information (NPI), triggering both PCI DSS and the FTC Safeguards Rule (16 CFR Part 314). The FTC Safeguards Rule, fully enforced since June 9, 2023, requires a written information security program, designated security coordinator, annual risk assessment, and multi-factor authentication for any system accessing customer financial data. COMNEXIA builds a single control set that satisfies both frameworks simultaneously, rather than running separate compliance projects. Microsoft Entra ID conditional access policies, for example, satisfy MFA requirements under PCI DSS Requirement 8 and the Safeguards Rule's access-control mandate at the same time, and those policies apply uniformly whether a service advisor is logging into Dealertrack or a billing workstation.

What Snellville Businesses Receive Each Month

COMNEXIA provides monthly reporting that maps patch status, endpoint protection coverage, SOC alert summaries, and backup verification results to specific PCI DSS requirement numbers. When your QSA or acquiring bank requests evidence of ongoing compliance activity, those reports serve as the audit trail. Help-desk support is delivered through a ticketed system with documented escalation paths, so every change to an in-scope system is recorded and attributable, satisfying PCI DSS change-management requirements under Requirement 6.5.
