PCI DSS Compliance & Payment Security Solutions
Protect payment environments. Reduce exposure. Strengthen payment data protection.
Payment environments are high-value targets. Weak network boundaries, excessive privileges, insecure configurations and inadequate monitoring can expose cardholder data and disrupt payment operations.
NS3TechSolutions strengthens the technical controls protecting payment infrastructure, whether you are securing a payment environment, reviewing existing controls or preparing for a Payment Card Industry Data Security Standard (PCI DSS) assessment.
“Every payment transaction depends on a secure environment behind it.”
Strengthen the Security of Your Cardholder Data Environment
PCI DSS applies to entities that store, process or transmit cardholder data or sensitive authentication data, and to systems that can affect the security of the cardholder data environment (CDE).
Protecting it takes coordinated controls across the areas below. We strengthen them with security solutions aligned to your existing architecture, risk profile and implementation requirements.
Control areas
- Network infrastructure
- User access
- System configurations
- Vulnerability management
- Security monitoring
