IT services to implement PCI-DSS technical controls for Lawton, Oklahoma businesses.
Network segmentation keeping payment systems separate from general business systems
Technical controls for secure handling of payment card information
Secure network architecture isolating payment processing systems
Implementation of encryption for cardholder data in transit and at rest
Regular patching and updates for payment-related systems
Implementation of PCI-DSS required technical safeguards
PCI-DSS (Payment Card Industry Data Security Standard) applies to any business that accepts, processes, stores, or transmits credit card data — regardless of size or transaction volume. A Lawton restaurant, retail store, or medical office taking card payments faces the same core technical requirements as a large enterprise.
The technical requirements cover six major areas: building and maintaining a secure network (firewalls, no vendor default passwords), protecting cardholder data (encryption), maintaining a vulnerability management program (security updates, anti-malware), implementing strong access controls, monitoring networks, and maintaining an information security policy.
DNS handles the IT infrastructure side of these requirements. We configure network segmentation to keep your payment systems isolated from general business traffic, set up firewalls with proper rule sets, implement encryption for cardholder data in transit, manage security patching schedules, and configure access controls so only authorized staff can access payment systems. We also set up logging and monitoring so your environment stays visible.
Formal PCI compliance validation — completing the Self-Assessment Questionnaire (SAQ) or working with a Qualified Security Assessor (QSA) — is handled through your payment processor or an independent QSA. We implement the technical controls; they validate and certify compliance.
DNS implements PCI-required technical IT controls. We do not perform PCI audits, complete SAQs on your behalf, or issue compliance certifications. For formal compliance validation, work with your payment processor or a Qualified Security Assessor (QSA).
The single most impactful PCI control for most small businesses is proper network segmentation — keeping payment systems separated from everything else.
Your point-of-sale terminals and payment processing systems live on a separate network segment. If general office computers get infected with malware, it cannot reach your payment environment.
Proper segmentation shrinks the number of systems that fall under PCI requirements. Fewer in-scope systems means a simpler, less expensive compliance process with your payment processor or QSA.
We set up logging and alerts so any unusual activity on payment-adjacent systems is flagged immediately — meeting PCI's requirement for continuous network monitoring and audit trail maintenance.
We implement the IT infrastructure and security controls that PCI-DSS requires.
We implement the technical controls required by PCI-DSS: network segmentation, firewall configuration, encryption, access controls, and secure WiFi. We handle the technology side of PCI compliance. Note: For official PCI assessments, SAQ completion, and compliance validation, you'll need to work with a Qualified Security Assessor (QSA) or your payment processor.
If your business accepts credit cards, debit cards, or any payment cards, you need to be PCI compliant. This applies to all businesses regardless of size or transaction volume. We can help implement the technical controls, but compliance validation must come from your payment processor or a QSA.
We implement network segmentation (separating payment systems from other business systems), firewalls, encryption for cardholder data, access controls, secure WiFi configurations, and regular security updates. These are the technical foundations that PCI-DSS requires.
We implement the technical controls that PCI-DSS requires, which is a significant part of compliance. However, we do not perform PCI assessments or audits ourselves. For official compliance validation, work with your payment processor or a Qualified Security Assessor (QSA).
