Real World Security Testing for Cardholder Data Environments and Payment Infrastructure
Orasec delivers results driven PCI DSS penetration testing services, identifying vulnerabilities that expose cardholder data environments, compromise payment infrastructure, and undermine the security controls required for Payment Card Industry Data Security Standard compliance. We go beyond surface level assessments by combining certified penetration testers, advanced methodologies, and real world attack simulation to uncover security weaknesses that genuinely impact organisations processing, storing, and transmitting payment card data.
PCI DSS penetration testing is not optional. Requirement 11.4 of PCI DSS v4.0 mandates penetration testing of cardholder data environments at least annually and after any significant infrastructure or application changes making structured, methodology driven penetration testing a direct compliance obligation for every organisation in scope.
Cardholder data environments concentrate high value financial data across payment applications, network segments, and supporting infrastructure. Attackers target payment environments for their direct financial value, exploiting network segmentation failures, application vulnerabilities, and access control weaknesses to reach cardholder data and payment processing systems.
Orasec's PCI DSS penetration testing methodology tests every layer of your cardholder data environment from network segmentation and payment application security to internal access controls and segmentation validation ensuring your security posture meets PCI DSS requirements and is resilient against the real world threats targeting payment environments today.
The cardholder data environment encompasses all systems, networks, and components that store, process, or transmit cardholder data. Poorly defined scope, inadequate segmentation, and undocumented data flows create compliance gaps and exploitable attack paths into payment data infrastructure.
PCI DSS requires effective network segmentation isolating cardholder data environments from out of-scope systems. Segmentation failures, misconfigured firewalls, and inadequate network controls allow attackers to reach cardholder data environments from lower security network segments.
Web applications, APIs, and payment processing systems handling cardholder data are primary attack targets. Injection vulnerabilities, broken authentication, insecure data transmission, and application logic flaws create direct paths to cardholder data theft and payment system compromise.
Internal systems, privileged accounts, and administrative interfaces within cardholder data environments require strong access controls. Weak credentials, excessive privileges, and misconfigured internal systems create lateral movement paths to payment processing infrastructure and cardholder data stores.
Payment gateways, processors, and third party service providers connect to cardholder data environments through APIs and network integrations. Insecure integrations, excessive third party permissions, and weak API authentication create indirect attack paths into payment infrastructure.
Wireless networks and remote access solutions connecting to or within cardholder data environments require specific security controls. Insecure wireless implementations and weak remote access controls create exploitable entry points into payment infrastructure.
We assess external network boundaries of cardholder data environments for vulnerabilities allowing unauthorised access from outside the organisation. Testing covers perimeter controls, externally exposed services, and attack paths into payment infrastructure from external network positions.
Our testers assess internal network controls, lateral movement paths, and access control effectiveness within and around cardholder data environments. Testing simulates an attacker who has gained initial internal network access attempting to reach payment systems and cardholder data.
We validate the effectiveness of network segmentation controls isolating cardholder data environments from out of-scope systems. Testing confirms whether segmentation controls prevent unauthorised access from connected network segments as required by PCI DSS Requirement 11.4.
Our testing evaluates web applications, APIs, and payment processing systems handling cardholder data for injection vulnerabilities, broken authentication, insecure data transmission, access control failures, and application logic weaknesses that create paths to cardholder data exposure.
We assess wireless networks operating within or connecting to cardholder data environments for insecure configurations, rogue access points, and authentication weaknesses that create unauthorised entry points into payment infrastructure.
Payment environment staff are targets of phishing and social engineering attacks seeking credentials and access to cardholder data systems. Orasec simulates real world social engineering campaigns to assess staff awareness and human targeted attack resilience across payment operations.
Cardholder data environment boundaries, data flows, connected systems, and segmentation controls are reviewed and confirmed to ensure penetration testing coverage aligns with PCI DSS scope requirements.
External attack surfaces are assessed for vulnerabilities allowing unauthorised access to cardholder data environments from outside organisational network boundaries.
Internal network controls, lateral movement paths, privilege escalation opportunities, and access control effectiveness are assessed from positions within and adjacent to cardholder data environments.
Network segmentation controls are actively tested to confirm effective isolation of cardholder data environments from out of-scope systems as required by PCI DSS v4.0 Requirement 11.4.
Payment applications, APIs, and cardholder data processing systems are assessed for application layer vulnerabilities using techniques aligned with OWASP testing methodologies and PCI DSS application security requirements.
Identified vulnerabilities are exploited to confirm real world impact, simulate lateral movement across cardholder data environment boundaries, and demonstrate paths to cardholder data and payment system compromise.
Findings are delivered in a detailed report structured to support PCI DSS compliance documentation requirements, with risk ranked vulnerabilities, exploitation evidence, segmentation validation results, and prioritised remediation guidance.
Connect with Orasec's certified testers to assess your cardholder data environment, payment applications, network segmentation, or internal access controls. Meet PCI DSS Requirement 11.4 obligations and identify real vulnerabilities before attackers exploit them.
