PCI DSS Security Assessments

Overview

Any organization that stores, processes, or transmits payment cardholder data is required to comply with the Payment Card Industry Data Security Standard (PCI DSS). Compliance is not optional. Failing to meet PCI DSS requirements exposes your organization to financial penalties, increased transaction fees, loss of card processing privileges, and significant reputational damage in the event of a breach.

PCI DSS mandates require businesses to perform periodic security assessments to protect cardholder data. These requirements, including network segmentation tests, must be conducted at least annually under PCI DSS Requirements 11.3, 11.1, and 6.6. Additional rounds of security assessments are mandatory following any significant changes to an organization's internal or external network and application architectures.

Poorly designed network configurations, weak access controls, and insecure coding practices remain the most common causes of cardholder data exposure. Organizations that store, process, and manage access to cardholder data must regularly verify the security of those environments through rigorous network and application monitoring and testing.

Redfox Cybersecurity delivers comprehensive PCI DSS security assessments that evaluate your compliance posture, identify vulnerabilities across your cardholder data environment, and provide the actionable evidence your auditors and regulators require.

What is a PCI DSS Security Assessment?

A PCI DSS security assessment evaluates your organization's adherence to the PCI DSS requirements designed to protect cardholder data and ensure the secure processing of payment transactions. The assessment covers the full scope of your payment card environment, including network infrastructure, segmentation controls, web applications, and wireless networks.

By conducting a PCI DSS security assessment, Redfox Cybersecurity helps you identify and address security vulnerabilities across your cardholder data environment, validate that your security controls meet PCI DSS requirements, and produce the documentation needed to support your compliance program.

We offer the following PCI DSS security assessments:

• PCI DSS Network Penetration Tests
• PCI DSS Segmentation Control Tests
• PCI DSS Web Application Penetration Tests
• PCI DSS Wireless Network Penetration Tests

How We Carry Out PCI DSS Security Assessments

Our PCI DSS security assessment service covers each required assessment type with a rigorous, structured methodology aligned to PCI DSS requirements and industry best practices.

PCI DSS Network Penetration Tests

We conduct thorough network penetration tests to identify vulnerabilities across your payment card network infrastructure. This includes assessing network devices, firewalls, routers, and switches for security weaknesses that attackers could exploit to gain unauthorized access to cardholder data. Our findings are documented to meet PCI DSS evidence requirements and provide your team with a clear remediation roadmap.

PCI DSS Segmentation Control Tests

PCI DSS requires proper network segmentation to isolate the cardholder data environment from other networks. We assess your segmentation controls by reviewing your network architecture, firewall rules, and access controls to verify that appropriate isolation measures are in place and that no unauthorized pathways exist between in-scope and out-of-scope systems. Effective segmentation both strengthens security and reduces the overall scope of your PCI DSS compliance program.

PCI DSS Web Application Penetration Tests

Web applications that process payment card transactions are a prime target for attackers. We conduct web application penetration tests aligned to PCI DSS requirements and the OWASP Top 10, identifying vulnerabilities including input validation flaws, injection attacks, authentication weaknesses, and insecure configurations. Our assessments help ensure the integrity and confidentiality of cardholder data across all payment-processing web applications.

PCI DSS Wireless Network Penetration Tests

Wireless networks present significant risk if not properly secured, particularly in environments connected to or present within the cardholder data environment. We perform wireless network penetration tests to identify security weaknesses across encryption protocols, authentication mechanisms, and access controls. Our assessments help you secure your wireless infrastructure and prevent unauthorized access to cardholder data.
