PCI Compliance IT Support in Roswell, GA

PCI Compliance IT Support in Roswell, GA

If your Roswell business accepts credit or debit card payments, the Payment Card Industry Data Security Standard (PCI DSS) is not optional. Failing an annual assessment, storing cardholder data in an unsecured system, or running unpatched point-of-sale software can result in fines from your acquiring bank, mandatory forensic audits, and loss of card-processing privileges. COMNEXIA has supported businesses in Roswell and across metro Atlanta since 1991, and PCI compliance is a concrete, documented process we walk clients through step by step, not a checkbox we hand off to a form.

What PCI DSS Actually Requires from Your IT Environment

PCI DSS v4.0 (effective March 2024) requires controls across twelve requirement domains, including network segmentation, access control, encryption of cardholder data in transit and at rest, vulnerability management, and logged monitoring of all access to card data. For most small and mid-size Roswell businesses qualifying under SAQ-B or SAQ-D, the practical IT work includes firewall configuration, MFA enforcement on every account that can reach the cardholder data environment (CDE), endpoint detection, and at least quarterly vulnerability scans by an Approved Scanning Vendor (ASV). COMNEXIA manages each of those layers directly.

How COMNEXIA Delivers PCI Compliance IT Support

Our process begins with a scoping call to identify every system, network segment, and user account that touches payment card data. We document the CDE boundary, then build the controls required to meet or exceed each applicable PCI DSS requirement:

• Network segmentation and firewall rule review. We isolate the CDE from general corporate traffic using VLAN separation and firewall ACLs. Point-of-sale terminals and payment applications sit on a dedicated network segment that cannot communicate laterally with workstations running email or web browsing.
• MFA and conditional access via Microsoft Entra ID. Every administrator and any user with access to payment systems is enrolled in Microsoft Entra ID conditional access policies that enforce phishing-resistant MFA (FIDO2 or Microsoft Authenticator) and block authentication from non-compliant or unmanaged devices.
• Endpoint detection and response with SentinelOne. SentinelOne EDR is deployed on all endpoints in or adjacent to the CDE. Its behavioral AI detects process injection, lateral movement, and memory-based attacks in real time. Alerts feed into our 24/7 SOC for triage, so a suspicious process on a POS workstation at 2 a.m. on a Saturday generates an immediate response, not a Monday morning ticket.
• Patch management via NinjaOne RMM. Operating system and third-party application patches are tested and deployed on a documented cadence. PCI DSS Requirement 6.3 mandates that critical patches be applied within one month. NinjaOne gives us patch-status reporting per device that we include in your monthly compliance report.
• Vulnerability scanning. We coordinate quarterly ASV scans against all external-facing IP addresses in scope and remediate findings before the scan window closes. Internal authenticated scans run monthly.
• Immutable, off-site backups (3-2-1). Cardholder data environments require data availability and integrity controls. We configure three copies of critical data on two different media types, with one copy stored off-site in an encrypted cloud vault, and we test restoration quarterly.
• Phishing-simulation and security-awareness training. PCI DSS Requirement 12.6 mandates a formal security-awareness program. We run monthly phishing simulations and track click rates by department, with follow-up training assigned automatically to anyone who engages a simulated lure.

PCI Compliance for Roswell Auto Dealerships

Auto dealerships in the greater Atlanta area face a layered compliance environment. The FTC Safeguards Rule (16 CFR Part 314) already requires dealerships to implement an information-security program protecting customer financial data, and that program overlaps significantly with PCI DSS controls when the dealership processes card payments for vehicle purchases, service-department transactions, or parts sales. Dealer management systems from CDK Global, Reynolds and Reynolds, and Dealertrack each have specific network and authentication requirements that our technicians know from direct experience. We configure firewall rules and Entra ID conditional access policies that work alongside those DMS platforms without disrupting service-writer or F&I workflows. If your Roswell dealership is preparing for an FTC Safeguards Rule assessment and an annual PCI self-assessment questionnaire simultaneously, COMNEXIA can map the overlapping controls so you are not running two parallel programs.

Monthly Reporting and Ongoing Documentation

PCI DSS compliance is not a one-time project. COMNEXIA delivers a monthly report covering patch compliance percentages by device, open vulnerability findings and remediation status, SOC alert summaries, backup test results, and MFA enrollment rates. That documentation is exactly what an assessor or acquiring bank asks for when reviewing your compliance posture.
