A Point-of-Sale (POS) system combines hardware and software to process transactions, manage inventory, and capture sales data for businesses such as retail stores, restaurants, and hotels. These systems handle highly sensitive cardholder data and are frequent targets for cyber attackers aiming to steal payment information.
A compromised POS device can silently capture card data or act as a launchpad for malware that spreads throughout your network, leading to costly data breaches, non-compliance penalties, and reputational damage. Our PCI POS Penetration Testing service evaluates the security of your POS devices, software, network segmentation, and supporting infrastructure to identify weaknesses that could expose cardholder data or allow unauthorized access.

Compliance & Hardening
Define in-scope locations, objectives, rules of engagement, and safety protocols for POS testing activities.
Identify all POS terminals, supporting infrastructure, and connected devices including servers, firewalls, and payment gateways.
Verify network isolation and firewall configurations in line with PCI DSS requirements to ensure proper segmentation from corporate and guest environments.
Assess POS hardware, firmware, and application software for misconfigurations, vulnerabilities, and insecure communication channels.
Map how cardholder data is captured, transmitted, and stored to detect potential leakage or exposure to non-secure systems.
Test authentication mechanisms, remote access policies, and privilege management to identify weak or shared credentials and unauthorized access paths.
Validate anti-malware coverage, detection effectiveness, and update mechanisms. Review endpoint telemetry and behavioral analytics for anomalies.
Produce a detailed report including an executive summary, scope, methodology, prioritized findings with PoCs, business impact, risk ratings, and actionable remediation. Present results during a restitution meeting.
POS systems are frequent targets for attackers aiming to steal payment card data. A compromised POS device can lead to data theft, PCI DSS violations, and severe financial losses. This assessment helps identify exploitable weaknesses, validate PCI DSS segmentation, and strengthen overall POS environment security.
Typically around 5 business days, depending on the environment’s size, number of POS devices, and network complexity.
All testing is conducted safely and non-destructively. For production systems, test windows are coordinated to avoid service disruption. Any potentially intrusive actions are performed only after explicit approval.
